    Incrementing Pointers Along arrays

    Code:
    char *key;
    char blah[10];
    
    gets(blah);
    key = blah;
    
    //How would I get a specific character from key?
    Ie. blah is qwerty

    I want to go through, using key, to get, say, the third character.

    how would I go about doing that? I was thinking putchar(key[2]); but that doesn't seem to be the case.

    Any help for this n00b would be appreciated

    Why not? It's perfectly legal
    Code:
    #include <stdio.h>
    
    int main(void)
    {
        char *key;
        char blah[10];
    
        gets(blah); /* gets is never correct, use fgets */
        key = blah;
    
        putchar(key[2]);
    
        return 0;
    }
    p.s. What the alphabet would look like without q and r.

    Yeah, it does work, ignore this thread. My brain said putchar, my body put putc, my Eyes read putc, and the error message spoke of macros.... lol
