I need to write a C program to fetch data from one file and write it to another file, without using user defined functions. My requirements are to:
Search customer details by Name.
Store the transaction data (paid amount) in another text file.
I did the code to search by name. But its not working,
#include <stdio.h>
#include <stdlib.h>
int main () {
char name[10], nic[10], mobile[10];
char fname[10], fnic[10], fmobile[10];
char choice;
int amount;
FILE *cfptr;
printf("Enter search type - \n 1. NAME \n 2. NIC \n 3.MOBILE \n ----> ");
scanf("%c", &choice);
printf("Enter search text : ");
scanf("%s", &name);
cfptr = fopen ("customer.dat", "r");
while (!feof(cfptr)){
fscanf(cfptr, "%s %s %s", fname, fnic, fmobile);
printf("Read Name |%s|\n", fname );
printf("Read NIC |%s|\n", fnic );
printf("Read Mobile |%s|\n", fmobile );
}
fclose(cfptr);
scanf("%d", &amount);
return(0);
}
customer.dat File
Shan 100012 200202
Marsh 121213 667675
Kim 126573 663412
This code is not complete asI cant filter the single name assigning
if(name == fname)
as am getting
assignment to expression with array type error
Can any one complete me the code to search and save to another file so I can do the amount calculation part?
int Search_in_File(char *fname, char *str) {
FILE *fp;
int line_num = 1;
int find_result = 0;
char temp[512];
//gcc users
//if((fp = fopen(fname, "r")) == NULL) {
// return(-1);
//}
//Visual Studio users
if((fopen_s(&fp, fname, "r")) != NULL) {
return(-1);
}
while(fgets(temp, 512, fp) != NULL) {
if((strstr(temp, str)) != NULL) {
printf("A match found on line: %d\n", line_num);
printf("\n%s\n", temp);
find_result++;
}
line_num++;
}
if(find_result == 0) {
printf("\nSorry, couldn't find a match.\n");
}
//Close the file if still open.
if(fp) {
fclose(fp);
}
return(0);
}
few comments:
when scanning the choice, read it as an integer and not as a character.
scanf("%c", &choice); // change to scanf("%d", &choice);
single '=' is an assigment, you meant comparison which is double '=='
if(name = fname) // comparison is if(name == fname)
in order to compare string, do not use '==' operator. use strcmp or implement an equivalent of strcmp.
Thanks for the effort, As with changes, I have changed my code as below and its working. Without checking with the name, I alternately checked with the nic.
#include <stdio.h>
int main(void){
int nic, n, mobile;
char name[30];
FILE *aPtr;
aPtr = fopen("Details.txt","w");
if(aPtr == NULL){
printf("File cannot be opened");
return -1;
}
printf("Enter nic to search - ");
scanf("%d", &n);
fscanf(aPtr, "%d %-s %d", &nic, name, &mobile);
while(!feof(aPtr)){
if(nic == n){
Printf("%d %s %d \n", nic, name, mobile);
}
fscanf(aPtr, "%d %s %d", &nic, name, &mobile);
}
fclose(aPtr);
return 0;

I am working on code for s blood donation system. I'm currently struggling with the delete donor record function.
The delete record function is to delete the record of a donor with a given name. If there are two or more records with the same name in the file then the program asks for mobile number. While there may be more than one person with the same name, each person has a unique mobile number.
My problem is that when the same name is used for several records, the wrong record is deleted.
If there's only one record with that name, the program deletes the record in the manner that's required.
(The variable i is declared globally as int i)
Here's the delete function
void delete(struct blood *b,int n)
{
char name[50];
int phone;
int found=0;
int c=0;
FILE *fp = fopen("bloodrecord.txt", "r");
FILE *fp1 = fopen("temp.txt", "w");
printf("\nEnter Name: ");
scanf("%s", name);
printf("---------------------------------------------\n");
while(fread(&b[i],sizeof(struct blood),1,fp))
{
if(strcmpi(b[i].name,name)==0)
{
c=c+1;
printf("\nName: %s\n",b[i].name);
printf("Age: %d\n", b[i].age);
printf("Mobile no.: %d\n", b[i].phone);
printf("Blood group: %s\n", b[i].bg );
printf("Weight: %d\n", b[i].weight);
printf("Sex: %s\n",b[i].sex);
printf("Address: %s\n",b[i].add);
printf("\n");
if (c==1)
{
found=1;
}
else if(c>1)
{
printf("\nThere are more than one occurences of this name in the records\n");
printf("\nPlease enter the mobile number of the donor: ");
scanf("%d", &phone);
if (b[i].phone == phone)
{
found=1;
}
}
}
else
fwrite(&b[i],sizeof(struct blood),1,fp1);
}
fclose(fp);
fclose(fp1);
if (found==1)
{
fp1 = fopen("temp.txt", "r");
fp = fopen("bloodrecord.txt", "w");
while(fread(&b[i],sizeof(struct blood),1,fp1))
{
fwrite(&b[i],sizeof(struct blood),1,fp);
}
fclose(fp);
fclose(fp1);
}
else
{
printf("\n\aRECORD DOES NOT EXIST.\n");
}
printf("RECORD SUCCESSFULLY DELETED");
getchar();
getchar();
}
I suggest that to make the program simpler, you request both the donor's name and the donor's mobile number at the beginning.
Then you process the input file and look for both name and mobile number in a single pass.
I started with your code and made a few changes. See comments.
Please note that I have not tested this code nor compiled it. It should be essentially correct however there may be a compiler error if I made a syntax mistake.
I assume that the you are using the struct blood correctly in your code since you did not provide the code defining that struct.
I assume that an int is sufficiently large to hold the mobile number. Since the size of an int can vary and is determined by the compiler, it may or may not be large enough for a mobile number. See Range of values in C Int and Long 32 - 64 bits
One thing I do not understand is why you are using the b[i] syntax and where is the variable i defined? You could instead use a local variable in the delete() function.
I also have the delete() function returning a value indicating if it found a match or not. This may or may not be useful.
int delete()
{
struct blood b;
char name[50] = {0};
int phone;
int found = 0;
FILE *fp = fopen("bloodrecord.txt", "r");
FILE *fp1 = fopen("temp.txt", "w");
// Ask for the donor's mobile number along with their name
// at the beginning to make the search easier and be able to
// do this in a single pass.
printf("\nEnter Name of the donor: ");
scanf("%49s", name); // Oka's comments about scanf().
printf("\nPlease enter the mobile number of the donor: ");
scanf("%d", &phone);
printf("---------------------------------------------\n");
while(fread(&b, sizeof(struct blood), 1, fp))
{
// check both donor's name and donor's mobile number.
if(strcmpi(b.name, name) == 0 && b.phone == phone)
{
// print out the donor data and indicate we are deleting
// this donor record.
printf("Deleting donor record\n");
printf(" Name: %s\n", b.name);
printf(" Age: %d\n", b.age);
printf(" Mobile no.: %d\n", b.phone);
printf(" Blood group: %s\n", b.bg );
printf(" Weight: %d\n", b.weight);
printf(" Sex: %s\n", b.sex);
printf(" Address: %s\n", b.add);
printf("\n");
found = 1;
}
else {
// we are keeping this donor record so write it to the
// temp file.
fwrite(&b, sizeof(struct blood), 1, fp1);
}
}
fclose(fp);
fclose(fp1);
if (found == 1)
{
// file temp.txt has deleted donors so lets updated
// the original file, bloodrecord.txt, with the updated
// list of donors.
fp1 = fopen("temp.txt", "r");
fp = fopen("bloodrecord.txt", "w");
while(fread(&b, sizeof(struct blood), 1, fp1))
{
fwrite(&b, sizeof(struct blood), 1, fp);
}
fclose(fp);
fclose(fp1);
printf("RECORD SUCCESSFULLY DELETED");
}
else
{
printf("\n\aRECORD DOES NOT EXIST.\n");
}
getchar();
getchar();
return found; // indicate if we found a match or not.
}
I reused most of your code, and added a second pass to handle the actual delete (first pass searches for matching records).
void delete(struct blood *b,int n)
{
const int MOBILE_SIZE = 16;
char name[50];
int phone = 0;
int found=0;
int c=0;
FILE *fp = fopen("bloodrecord.txt", "r");
FILE *fp1 = fopen("temp.txt", "w");
printf("\nEnter Name: ");
scanf("%s", name);
printf("---------------------------------------------\n");
while(fread(&b[i],sizeof(struct blood),1,fp))
{
if(strcmpi(b[i].name,name)==0)
{
c=c+1;
printf("\nName: %s\n",b[i].name);
printf("Age: %d\n", b[i].age);
printf("Mobile no.: %d\n", b[i].phone);
printf("Blood group: %s\n", b[i].bg );
printf("Weight: %d\n", b[i].weight);
printf("Sex: %s\n",b[i].sex);
printf("Address: %s\n",b[i].add);
printf("\n");
found = 1;
}
}
/* Finished the first pass. Now, start again */
rewind(fp)
if (c > 1) {
printf("There are multiple records for the name %s\n", name);
printf("\nEnter Mobile Number: ");
scanf("%d", &phone);
}
while(fread(&b[i],sizeof(struct blood),1,fp))
{
if((c == 1 && strcmpi(b[i].name,name)==0)
|| (c > 1 && strcmpi(b[i].name,name) == 0 && b[i].mobile == mobile))
continue; /* skip this record */
}
else
fwrite(&b[i],sizeof(struct blood),1,fp1);
}
fclose(fp);
fclose(fp1);
if (found==1)
{
fp1 = fopen("temp.txt", "r");
fp = fopen("bloodrecord.txt", "w");
while(fread(&b[i],sizeof(struct blood),1,fp1))
{
fwrite(&b[i],sizeof(struct blood),1,fp);

I created a file and filled it with some entries. However, I want to read this file and show it on the screen. Also, after showing the entries, I want it to be deleted with my permission. But I am stuck at this point please help me.
EDIT: Code is updated but still couldn't figure it out how to do :/
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
char name[20], surname[20], city[30], country[30], gender[15];
int count = 0;
int main() {
FILE *f1;
f1 = fopen("C:\\FurkanArslan.txt", "r+");
while (count < 10) { // every step provides 5 new data, so 5*10 will provide 50 data in total.
printf("\n*Please enter required information: \n");
printf("Name :"); scanf("%s", name);
printf("Surname:"); scanf("%s", surname);
printf("Country:"); scanf("%s", country);
printf("City :"); scanf("%s", city);
printf("Gender :"); scanf("%s", gender);
fprintf(f1, " %s | %s | %s | %s | %s\n\n", name, surname, gender, city, country);
count++;
}
fclose(f1);
printf("\n<<<<<%d data has been successfully saved!>>>> \n", count * 5);
printf("-------------------------------------\n");
f1 = fopen("C:\\FurkanArslan.txt", "r");
char c, answer;
while ((c = fgetc(f1)) != EOF)
putchar(c); // In this part I displayed file on the screen.
printf("\n\n <<<< %d entries are displayed on the screen! >>>>", count * 5);
printf("\n\nWould you like to remove your file [Y/N] ?");
scanf(" %c", &answer);
if (answer == 'y' || answer == 'Y') {
remove("f1");
printf("\n\n***File successfully removed!");
}
return 0;
}
In order to show the content of a file you have to open it and read it letter by letter, after that, you can use the putchar function to output the current character
FILE *fp = fopen("path/to/file.txt","r");
char c;
while((c=fgetc(fp))!=EOF)
putchar(c);
fclose(fp);
after that to remove a file you need to use the remove function, which receives the name of the file as paramter.
remove("my_file.txt");
There are multiple issues in your code:
there is no need to make the variables and arrays global, just define them in the body of the main() function.
you should tell scanf() the maximum number of characters to store in the destination array with a length specifier in the format string (eg: "%19s") and check for conversion success.
the variable c used in the reading loop must have type int for proper detection of EOF. fgetc() returns a positive byte value if successful and the special negative value EOF at end of file.
you do not need to reopen the file after writing to it. Sine you opened it for update mode, you can just seek back to the beginning of the file with rewind(f1) or fseek(f1, 0L, SEEK_SET).
the file is open for read and update mode ("r+"): it will fail if the file does not exist. You should open it in write and update mode with "w+" to create or truncate it.
you should check that fopen succeeds at opening the file, otherwise you invoke undefined behavior passing a null stream pointer to fprintf.
to remove the file, remove() takes the filename as its argument. You must close the file before attempting to remove it.
Here is a modified version:
#include <errno.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main() {
const char *filename = "C:\\FurkanArslan.txt";
char name[20], surname[20], city[30], country[30], gender[15];
int count = 0;
FILE *f1 = fopen(filename, "w+");
if (f1 == NULL) {
printf("Cannot open file %s.\n", filename);
return 1;
}
while (count < 10) { // every step provides 5 new data, so 5*10 will provide 50 data in total.
printf("\n*Please enter required information: \n");
printf("Name :"); if (scanf("%19s", name) != 1) break;
printf("Surname:"); if (scanf("%19s", surname) != 1) break;
printf("Country:"); if (scanf("%29s", country) != 1) break;
printf("City :"); if (scanf("%29s", city) != 1) break;
printf("Gender :"); if (scanf("%14s", gender) != 1) break;
fprintf(f1, " %s | %s | %s | %s | %s\n\n", name, surname, gender, city, country);
count++;
}
printf("\n<<<<< %d data has been successfully saved to %s! >>>>\n",
count * 5, filename);
printf("-------------------------------------\n");
rewind(f1);
int c;
while ((c = fgetc(f1)) != EOF)
putchar(c);
printf("\n\n <<<< %d entries are displayed on the screen! >>>>\n", count);
fclose(f1);
printf("\nWould you like to remove your file [Y/N] ?");
char answer;
if (scanf(" %c", &answer) == 1 && (answer == 'y' || answer == 'Y')) {
if (remove(filename)) {
printf("\n\n***Error removing file %s: %s\n",
filename, strerror(errno));
} else {
printf("\n\n***File %s successfully removed!\n", filename);
}
}
return 0;
}
I'm able to write data into a file but when I read it, it prints an empty file. I tried to make 2 programs one to write to file using permission "w" and one to read using "r" but when I combined both programs and changed permission to "w+" printing the files gives lots of empty spaces.
#include <stdio.h>
#include <stdlib.h>
void main()
{
char name[20];
char roll_no[15];
char class[10];
char semester[10];
char course[20];
FILE *file_pointer;
file_pointer = fopen("StudentRecords.txt", "w+");
if (file_pointer == NULL)
{
printf("\nError Opening File StudentRecords.txt\nCreate File Manually and Try Again.");
exit(1);
}
printf("\nENTER DETAILS FOR 5 STUDENTS\n");
//TAKE 5 RECORDS FROM USERS AND SAVE THEM IN FILE-
for (int i = 1; i <= 5; i++)
{
printf("\nStudent %d", i);
fprintf(file_pointer, "Student %d", i);
printf("\nName : ");
scanf("%s", &name);
fprintf(file_pointer, "\nName : %s", name);
printf("Roll No : ");
scanf("%s", &roll_no);
fprintf(file_pointer, "\nRoll No : %s", roll_no);
printf("Class : ");
scanf("%s", &class);
fprintf(file_pointer, "\nClass : %s", class);
printf("Semester : ");
scanf("%s", &semester);
fprintf(file_pointer, "\nSemester : %s", semester);
printf("Course : ");
scanf("%s", course);
fprintf(file_pointer, "\nCourse : %s", course);
printf("\n");
fprintf(file_pointer, "\n\n");
}
//READ ENTIRE FILE WORD BY WORD
char c;
c = fgetc(file_pointer);
while (c != EOF)
{
printf("%c", c);
c = fgetc(file_pointer);
}
fclose(file_pointer);
}
When you write/read in a file you use a stream (FILE*) that stores where in the file you are (position).
When you finished writting that was the last stream position.
You need to go back to the begin of the file if you want to read it entirely.
You can use fseek for this.
int fseek(FILE *stream, long int offset, int whence);
1 SEEK_SET : Beginning of file
2 SEEK_CUR : Current position of the file pointer
3 SEEK_END : End of file
...
//READ ENTIRE FILE WORD BY WORD
char c;
fseek(file_pointer, 0, SEEK_SET);
c = fgetc(file_pointer);
while (c != EOF)
{
printf("%c", c);
c = fgetc(file_pointer);
}
For the read section do this instead. This will reset the position indicator to the beginning of the file so you can read from the beginning.
if ( fseek(file_pointer, 0L, SEEK_SET) == 0 ) {
char c;
c = fgetc(file_pointer);
while (c != EOF)
{
printf("%c", c);
c = fgetc(file_pointer);
}
}
I am a complete beginner of C. My problem is to modify a content in a file.
I am writing two files and then merge the contents of the two files in a another file. This another file is the one I need to modify.
what to modify?
The myfile1.txt values are 199112345671273 and the myfile2.txt values are 24AUS2024MED712.
The merging file (myfile3.txt) has 19911234567127324AUS2024MED712
The thing that I need to modify is the values of myfile2.txt. I want to hide its values in asterisk so when reading myfile3.txt,I get the following
199112345671273****************
my logic is messed up. I just want to stores both values of myfile1 and myfile2. then display myfile3 in condition that myfile2 has to be hidden in asterisk when reading.

My issue is my logic on how to solve this simple program. I am literally stuck.
Any help/clarification would be much appreciated.
In this case you need to create a program which should know the content/size of 'myfile1.txt' or 'myfile2.txt' so as to show * for the second content while reading 'myfile3.txt'.
I prefer not to create separate c programs for each task but to use it as a function in one single program.
Coming to the logic : Masking is what you are searching for. Basically it is used as a password masking. ( You might have seen * while typing password in any sites. ). In your case you want to display a content as * without actually changing the content in file.
Get an idea of how masking is done for password in the below document :
https://www.geeksforgeeks.org/print-in-place-of-characters-for-reading-passwords-in-c/
Hope you have tried all possible way out. Please check the solution below :
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char **argv) {
char c1[1000];
char c3[1000];
FILE *fptr, *anotherfptr;

// reads text until newline

exit(1);
}
// reads text until newline

//to show data of myfile2.txt in astrisk

for ( int i=0 ; i<=lengthc3 ; i++)

I was under the impression that to open binary files using strings, you could simply create the string, and then implement it as the name of the file where it will read the string. This is what my lecture notes state. However I'm obveously missing something. I've used &name, name, &name[SIZE] within the fopen and each time i've gotten inBinFile == NULL unless I use the commented line. My string is correct. What's wrong? Help is much appreciated. Thanks in advance.
