I have written the following program which is working fine when I compile the program in x86 configuration but when I change the configuration of the platform to x64, my program doesn't work at all. Where is the problem:
int main(int argc, char* argv[])
{
char* cp_UserName[MAX_PATH];
char* cp_DomainName[MAX_PATH];
char* cp_HashNtlm[MAX_PATH];
char* cp_ComputerName[MAX_PATH];
DnPthIconSetup();
DnPthInitialization(TRUE);
if (argc > 4)
{
for (size_t i = 1; i <= sizeof(argv); i++)
{
if (strstr(argv[i], "user") != NULL)
{
strtok_s(argv[i], ":", cp_UserName);
}
if (strstr(argv[i], "domain") != NULL)
{
strtok_s(argv[i], ":", cp_DomainName);
}
if (strstr(argv[i], "pc") != NULL)
{
strtok_s(argv[i], ":", cp_ComputerName);
}
if (strstr(argv[i], "ntlm") != NULL)
{
strtok_s(argv[i], ":", cp_HashNtlm);
}
}
printf("%s\n", *cp_UserName);
printf("%s\n", *cp_DomainName);
printf("%s\n", *cp_ComputerName);
printf("%s\n", *cp_HashNtlm);
system("PAUSE");
// ParametricCredentialDispatcher(cp_UserName, cp_DomainName, cp_HashNtlm, cp_ComputerName);
}
else if (argc == 1)
{
InteractiveMode();
}
else
{
printf("\nUsage: ./program user:[] domain:[] pc:[] ntlm:[]\n");
system("PAUSE");
}
return 0;
}
sizeof(argv) is a size of the pointer, not number of arguments.
Your usage of strstr will result into wrong result when, for example, the arguments contains pc:computer_for_an_user.
This usage of strtok_s will store pointer to the name of configurations, not their values.
Possible fix of the parsing part:
for (size_t i = 1; i < arc; i++)
{
if (strncmp(argv[i], "user:", 5) != NULL)
{
*cp_UserName = strchr(argv[i], ':') + 1;
}
if (strncmp(argv[i], "domain:", 7) != NULL)
{
*cp_DomainName = strchr(argv[i], ':') + 1;
}
if (strncmp(argv[i], "pc:", 3) != NULL)
{
*cp_ComputerName = strchr(argv[i], ':') + 1;
}
if (strncmp(argv[i], "ntlm:", 5) != NULL)
{
*cp_HashNtlm = strchr(argv[i], ':') + 1;
}
}
The added : in the arguments of strncmp is assuming that strchr won't return NULL.
Also you should initialize the pointers and check if they are not NULL before passing them to printf.

My code traverses through command line arguments. if the command line contains "alice.txt" index zero of an empty array is filled with "alice.txt" This also applies to "anh.txt" if it is present, then index 1 is filled with "anh.txt". When i type in the command line ./wc alice.txt anh.txt it will print out words line and characters of both files. however if I just do /wc anh.txt i will get "NULL FILE" I suspect this is because of index zero being NULL, I wrote it so it would print "NULL FILE" and then exit the program. How can I modify my code so it doesn't exit, rather skips to the next index? This is what I have for code:
int main(int argc, char **argv)

I'm writing a word, character, line counter for files in C. Im using a function get_counts to get these numbers. Right now I'm trying to get these values for two files. However, when I call it twice, the values don't reset to zero. I don't understand why because I declare the array to be {0,0,0} before I do any counting when I call the function. Here is my code. Currently just trying to get the line counter to work in print_counts. i'm sending it two files, one file has 3735 lines and the other file has 21. I keep getting an output of 3756.
int *get_counts(char *filename)
{
FILE *file = fopen(filename, "r");
if (file == NULL)
{
printf("NULL FILE");
exit(1);
}
int c;
bool whitespace = true;
static int arr[3] = {0,0,0};
for(;;)
{
c = fgetc(file);
if (c == EOF)
{
break;
}
else if (c == '\n')
{
arr[0]++;
}
else if (whitespace && !isspace(c))
{
arr[1]++;
whitespace = false;
}
else if (!whitespace && isspace(c))
{
whitespace = true;
}
arr[2]++;
}
fclose(file);
return arr;
}

{
printf("%d", count[0]);
}
}
}
int main(int argc, char **argv)

{
argArray[0] = 1;
}
if (strcmp(argv[i], "-w") == 0)

print_counts(argArray, myArrayAlice, *nameArray);

return 0;
}
I don't understand why because I declare the array to be {0,0,0}
before I do any counting when I call the function.
Because is defined as static, remove the static keyword switching to int *arr = calloc(3, sizeof(int); or passing arr[3] from main and calling memset(arr, 0, 3 * sizeof(int)); in the function if you prefer to avoid dynamic memory.
I'm trying to read from a file using C and after shrinking the size using realloc I get corrupted data. I don't really see what the problem could be.
Here's the function that returns the string :
char *read_string(FILE *fichier) {
char car = 0;
size_t size = 1;
char *symbole = realloc(NULL, sizeof(char) * size);
char *s;
size_t len = 0;
if (!symbole)
return symbole;
else
s = symbole;
do {
car = getc(fichier);
} while (car != '"' && car != EOF);
if (car == EOF)
return EOFP;
else {
car = getc(fichier);
while (car != '"' ) {
s[len] = car;
car = getc(fichier);
len++;
if (len == size) {
symbole = realloc(s, sizeof(char) * (size += 1));
if (!symbole)
return symbole;
else
s = symbole;
}
}
s[len] = '\0' ;
symbole = realloc(s, sizeof(char) * len);
if (!symbole) {
printf("WTF");
return symbole;
} else
s = symbole;
return s;
}
}
My main function is:
int main(int argc, char *argv[]) {
FILE *fichier = NULL;
fichier = fopen("C:/Users/Nabila K/Documents/test.json", "r");
if ((fichier != NULL)) {
while (feof(fichier) == 0) {
char *test = read_string(fichier);
if (test == NULL) {
printf("test == NULL\n");
exit(1);
} else
if (test == EOFP) {
} else {
printf("%s\n", test);
free(test);
}
}
fclose(fichier);
} else {
exit(EXIT_FAILURE);
}
return 0;
}
UPDATE
My json file looks something like this :
{
"KARIM BENNI" : {
"2017-08-07 09:50:50" : {
"Anomalie" : {
"description" : "Test",
"theme" : "Engins mobiles"
},
"date" : "2017-08-07",
"date_now" : "2017-08-07 09:50:50",
"entite" : "USINE LAMINAGE A FROID",
"etat" : "Cree",
"nb_personne" : 2,
"temps" : 5,
"visiteur" : "KARIM BENNI",
"visite" : "AHMED RABII",
"zone" : "COUPE"
}
}
}
There are multiple issues in your code:
char car = 0; is incorrect: you must define car as int to correctly distinguish all values returned by getc(), especially EOF.
while (feof(fichier) == 0) is always wrong. Learn why there: Why is “while ( !feof (file) )” always wrong?
EOFP is not defined, you should probably use NULL instead for more clarity.
the final realloc() to shrink the allocated block is one byte too short. You must keep len+1 bytes for len characters plus the null terminator.
Here is a simplified and corrected version:
#include <stdio.h>
#include <stdlib.h>
char EOFP[1]; /* special value used to signal end of file */
char *read_string(FILE *file) {
int c;
size_t size, len;
char *symbol;
char *s;
while ((c = getc(file)) != '"') {
if (c == EOF)
return EOFP;
}
size = 16;
len = 0;
symbol = malloc(size);
if (symbol == NULL) {
/* allocation failure */
return NULL;
}
while ((c = getc(file)) != '"') {
if (c == EOF) {
/* premature end of file in the middle of a string */
free(symbol);
return EOFP;
}
if (len + 2 < size) {
size += size;
s = realloc(symbol, size);
if (s == NULL) {
/* allocation failure */
free(symbol);
return NULL;
}
symbol = s;
}
symbol[len++] = c;
}
symbol[len] = '\0';
s = realloc(symbol, len + 1);
return s ? s : symbol;
}
int main(int argc, char *argv[]) {
FILE *file = fopen("C:/Users/Nabila K/Documents/test.json", "r");
if (file != NULL)) {
char *test;
while ((test = read_string(file)) != EOFP) {
if (test == NULL) {
printf("test == NULL\n");
exit(1);
} else {
printf("%s\n", test);
free(test);
}
}
fclose(file);
} else {
exit(EXIT_FAILURE);
}
return 0;
}
Notes:
Parsing the full JSON syntax for strings would be required if the strings can contain escaped characters such as \" or \n, \\ etc.
I write program which sort numbers like 23.44 12.4223. And almost everything works fine but it does not sort correctly numbers for instance 24.321 and 24.33 i mean for my rpgoram 24.321 is greater than 24.33
Infile contains numbers like 34.5 123.55. 56. .43 564.3

In your program 24.321 is greater than 24.33 because length of 24.321 is greater than length of 24.33.
You should stop increasing length when you read ..
Fix:
//UPDATE
while(*curr1=='0') curr1++;
while(*curr2=='0') curr2++;
//END OF UPDATE
char dot1 = 0, dot2 = 0;
char err1 = 0, err2 = 0;
while(*curr1 || *curr2)
{
if(*curr1 == '.') ++dot1; //UPDATE2
if(*curr2 == '.') ++dot2; //UPDATE2
while(*curr1 == '.')
curr1++;
while(*curr2 == '.')
curr2++;
if(value == 0)
{
value = *curr1 - *curr2;
}
if(*curr1)
{
if(*curr1 < '0' || *curr1 > '9') err1 = 1;
curr1++;
if(!dot1) len1++;
}
if(*curr2)
{
if(*curr2 < '0' || *curr2 > '9') err2 = 1;
curr2++;
if(!dot2) len2++;
}
}
if(err1 || err2 || dot1 > 1 || dot2 > 1) exit(1); // UPDATE2
UPDATE:
I updated code. Now before main comparison while only zeros are skipped. Dots will be skipped at the beginning of main while and fix with dot1 and dot2 will work.
UPDATE2:
To check if numbers are correct you should count dots and check if all chars are dots or digits.
Be aware that for longer bad numbers (more than 255 dots) my code could not work correctly (because dot1 is 1 byte long). If you need to handle these cases you should check if dot1/dot2 are equal to 1 and change err1/err2 to 1 instead of increasing dot1/dot2.
Your problem is here:---
if(len1 != len2)
{
return (len1 > len2) ? 1 : -1;
}
For strings "24.321" len1 = 6 ,"24.33" len2 = 5 so the longest string wins.
I thing your algorithm will also encounter problems with 123.45 vs 23.456 as you are basically ignoring the decimal point.
You could try converting to floating point (use function atof() or strtof() ) to convert the string to a real real number then compare.
Or simply return "less than" if you encounter a '.' in the first string before you encounter it in the second string.
I am trying to fix my last problem and still, I cannot figure out how to solve it. My task was to write a program which sort numbers, but: our tutor gives us some extra points for program dealing with numbers like: 000054667 (in fact 54667) and 345_845 (in fact 345845). The first problem is already solved but I have no idea how to handle with the second one. Hence, my question is: do you have any tips/clue, which might help me? I am also sending my code:

Thank you for any help ;)
Change string accumulation and your compare routine.
String accumulation:
if(isdigit(c) || (c == '_'))
Compare. This is a bit lengthy to incorporate ignoring _ for value ratings. But it is not limited to numbers that fit in any int range.
int compare(const void *str1, const void *str2) {
const char* curr1 = *(const char**) str1;
const char* curr2 = *(const char**) str2;
// Remove leading zeros
while ((*curr1 == '0') || (*curr1 == '_'))
curr1++;
while ((*curr2 == '0') || (*curr2 == '_'))
curr2++;
int value = 0;
size_t len1 = 0;
size_t len2 = 0;
while (*curr1 || *curr2) {
while (*curr1 == '_')
curr1++;
while (*curr2 == '_')
curr2++;
// If a difference has not been found yet ...
if (value == 0) {
value = *curr1 - *curr2;
}
if (*curr1) {
curr1++;
len1++;
}
if (*curr2) {
curr2++;
len2++;
}
}
// If significant digits in string1 more than string2 ...
if (len1 != len2) {
return (len1 > len2) ? 1 : -1;
}
return value;
}
Just keep parsing the string until you get an underscore, and with parsing also convert each character into the respective number and keep adding it to a new number according to it's place value (In a nutshell i'm speaking of an algorithm to convert string to numbers). and if you encounter an underscore, just use
continue;
If you want to retain the string representation for your "numbers" but compare them according to their numerical value, don't compare them as strings inside your compare function.
Inside compare parse each arguments (str1 and str2) and convert them to numbers skipping leading zeros and underscores. Once you have two numbers (say num1 and num2) just return num1 - num2.
Instead of storing a bunch of strings, you would be better off converting the numbers to ints by stripping out any non-digit characters and calling atoi on the results. You can store those numbers directly in the array. The compare function then becomes much simpler.
chux THX. You're brilliant! I wish I would be as good as you in programming.
