Thread: Split string in sequential file to add a tabstop between the strings...

Code:

do:
   try to read some stuff
   if there is some stuff, then:
      split the string
      display the resulting strings
while there is some stuff.

Something like this.

You have to stop RIGHT AWAY. Once you type "char *gpa=", it's too late -- that is not right away any more. You cannot try to process the data if it isn't there.

Guys I appreciate all the help. I have tried the if statement with !=NULL and ==NULL in it's current location and still getting segmentation fault. I am pulling my hair out with this one.

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define N 100

int main()
{
    FILE *fP;
    char str[N], *c;
    /*char *gpa = strchr(str, ' ');*/


    if ((fP = fopen("names.dat", "r")) == NULL)
    {
        printf("%s not opened", "names.dat");
        exit(EXIT_FAILURE);
    }
    do {
        c = fgets(str, N ,fP);
        if (c != NULL);
        char *gpa = strchr(str, ' ');
        *gpa++ = '\0';
        printf("%s\t%s\n", str, gpa);




        }
    while (c != NULL);

    fclose(fP);

    return 0;

}

I really do not know what to do here. Again, guys I truely appreciate your time with me.

          printf("%s\t%s\n", str, gpa);
        }
      }while (c != NULL);

Or more simply:

Code:

while(fgets(str, N, fP))
{
  char *gpa = strchr(str, ' ');
  *gpa++ = '\0';
  printf("%s\t%s\n", str, gpa);
}

Oh thank GAWD! or should I say all of you! Thank you very much!
