Question

running UNIX through putty, and using vi and gcc.
I am attempting to read in a line of a file and using a ragged array store the lines.
I won’t provide the whole code because it is unnecessary,

main(){
   char func[51];
   char * functions[201];
   FILE * inf;
   if (( inf = fopen("test.txt", "r")) == NULL){
       printf("can't open so exiting\n");
       exit(EXIT_SUCCESS)


   int i;
   i = 0;
   while( fscanf(inf, "%s", func) != EOF){
        functions[i] = func;
        i++;
   }
   printf("%s\n", *functions); /* this is just for me to check if its working*/

   }

incldues stdio.h, stdlib.h and string.h

SO the code works in that it runs through the file and during the while loop it stores the line but I want it so that functions[0] stores a pointer leading to the first line and functions[1] stores a pointer leading to the second line and so on. I’m not sure how to do this, any help would be appreciated thanks 🙂

You need to assign a copy of func to functions[i], as in functions[i] = strdup(func), if you have strdup.
