For your implementation of the divide function , i have created the
following test case (which I guess was what Mark was asking you to do).

#include <stdio.h>
#include <stdlib.h>

void divide(char search_string[], char *array[], char *delimiter){
int loop;
array[0]=strtok(search_string,delimiter);

if(array[0]==NULL)
{
printf("No test to search.\n");
exit(0);
}

for(loop=1;loop<50;loop++)
{
array[loop]=strtok(NULL,delimiter);

if(array[loop]==NULL)
break;
}

for(loop=0;loop<50;loop++)
{
if(array[loop]==NULL)
break;
//printf("\nDivide - array[%d] = %s", loop,array[loop]);
}
}

int main(void) {
int i = 0 ;
char *arr[50];

divide("this,is,comma,separated,string", arr ,",");

printf("Divided contents\n");
for(i = 0; i < 50; i++)
{
if(arr[i]==NULL)
break;

printf("%s \n", arr[i]);
}
return 0;
}

I am not sure what you want to return from divide function.

I can do that inside main. What i can't do is with divide:

char divide(char search_string[], char *array[], char *delimiter)

and return the string you printed! Can this be done?
