Im trying to get a sample source code, that will tell me how to read a files 3rd line, save it to a string, and then cut off the last 4 characters of that string. Thanks for any help!

#include <stdio.h>
main(){
       char string[1000];
        int i;
        fgets (string, 999, stdin);
        fgets (string, 999, stdin);
        fgets (string, 999, stdin);
      if( (i = strlen(string)) >= 4 ){ string[i-4] = '\0'; };
      printf("'%s'\n",string);
}
