Question

I have an assignment where I’m supposed to loop through a Character Array using a Recursive Function. I figured it would be easy since I would know the length of the array but then the prototype is give to me which I have to use:

void display(char str[])

I can’t imagine how I’m supposed to loop through this recursively without knowing the length. Can anybody give me a nudge on this please?

Answer 1

void display(char str[])
{
    if (*str) {
        putchar(*str);
        display(str+1);
    }
}
