How about dynamic memory allocation!?:
        int *integerPtr = new int[10];

Or, searching for a character in a string:
    char *aString = "Hello!";
    char *ptr = aString;

    while( *ptr ) {
        if( *ptr == 'e' )
            printf("Found the letter 'e'!\n");

        ptr++;
}

I hope this is all you need to keep you from banging your head against
the monitor :)

Regards,
Chris Bill
