Question

Could find a similar thing for C here.

I need to break a sentence into a an char array based on occurrence of a character example: %

Example

If my sentance is my%healthy%dog then i should be able to get my, healthy and dog separately.
This could be in a loop as well.

strtok is the standard C function to achieve string tokenizing.

#include <stdio.h>
#include <string.h>

int main()
{
        char c[] = "my%healthy%dog";
        char *token = strtok(c, "%");
        while (token != NULL)
        {
                printf("%s\n", token);
                token = strtok(NULL, "%");
        }
        return 0;
}


$ ./a.exe
my
healthy
dog

Also note that strtok uses static variables internally, so it is not threadsafe. For threadsafety, you’ll have to use the strtok_r function.
