delimiter in C without built-in string functions - c

Question

in today task i had to implement the function "my_split" that is based on pointers and accessing addresses, I'm having a little bit of trouble with "catching" all of the content from the file into the output.
this is my function:
void my_split(const char *source, char *first, char *second, const char delim){
int ree = 1;
while(*source != '\n'){
if(*source == delim){
ree = 0;
*source++;
}
else{
if(ree == 1){
*first++ = *source++;
}
else {
*second++ = *source++;
}
}
}
*first = '\0';
*second = '\0';
}
Main function:
int main(void){
int max_n = 200;
char source[max_n];
char strA[max_n];
char strB[max_n];
int T;
scanf("%d%*c", &T);
for(int i = 0; i < T; i++){
fgets (source, max_n, stdin);
my_split(source, strA, strB, ';');
printf("First: %s\n", strA);
printf("Second: %s\n", strB);
}
}
^^^ teacher gave us this one.
TXT FILE:
2
2345.454;6737.98
this is the line;splitted by semicolon
My output is:
First:
Second:
First: 2345.454
Second: 6737.98
The desired output is:
First: 2345.454
Second: 6737.98
First: this is the line
Second: splitted by semicolon
I'm trying to make above function, but It didn't workout, well it works half-succesfull

Your function seem to work. Try it like this...
#include <stdio.h>
void my_split(const char *, char *, char *, const char);
int main() {
FILE* fp;
fp = fopen("data.txt", "r");
if (NULL == fp) {
printf("file can't be opened \n");
return 0;
}
char source[100];
while (fgets(source, 100, fp) != NULL) {
char first[100] = "", second[100] = "";
my_split(source, first, second, ';');
printf("First: %s\n", first);
printf("Second: %s\n", second);
}
// Closing the file
fclose(fp);
return 0;
}
void my_split(const char *source, char *first, char *second, const char delim){
int ree = 1;
while(*source != '\n'){
if(*source == delim){
ree = 0;
*source++;
}
else{
if(ree == 1){
*first++ = *source++;
}
else {
*second++ = *source++;
}
}
}
*first = '\0';
*second = '\0';
}
It outputs:
First: 2
Second:
First: 2345.454
Second: 6737.98
First: this is the line
Second: splitted by semicolon
