Without the source code portion in question any answer can not be more than an educated guess.

However here's a snippet for guidance.

Code:
#include <stdio.h>
#include <ctype.h> /* for tolower function */

int main (void)
{
    char *word = "HolA";

   /* ignore the mechanism to bring the exercise to pass, it could be any loop */
    while (*word) {
        if (tolower(*word) == 'a') { /* here's the working bit */
            printf("Found an '%c'\n", *word);
        }
        ++word;
    }
    return 0;
}

ustrtok(3alleg4)						  Allegro manual						  ustrtok(3alleg4)

NAME
ustrtok - Retrieves tokens from a string. Allegro game programming library. SYNOPSIS
#include <allegro.h> char *ustrtok(char *s, const char *set); DESCRIPTION
This function retrieves tokens from `s' which are delimited by characters from `set'. To initiate the search, pass the string to be searched as `s'. For the remaining tokens, pass NULL instead. Warning: Since ustrtok alters the string it is parsing, you should always copy the string to a temporary buffer before parsing it. Also, this function is not re-entrant (ie. you cannot parse two strings at the same time). Example: char *word; char string[]="some-words with dashes"; char *temp = ustrdup(string); word = ustrtok(temp, " -"); while (word) { allegro_message("Found `%s' ", word); word = ustrtok(NULL, " -"); } free(temp); RETURN VALUE
Returns a pointer to the token, or NULL if no more are found. SEE ALSO
