Hello, this is my first post.

I have this function for reversing a string in C that I found.

    void reverse(char* c) {
        if (*c != 0) {
            reverse(c + 1);
        }
        printf("%c",*c);
    }

It works fine but if I replace:

reverse(c + 1);

with:

reverse(++c);

the first character of the original string is truncated. My question is why would are the statements not equivalent in this instance?

Thanks
