Thread: l-value? (Pointer)

Please help me resolve this. What did I do wrong?

Code:

char *findC (char const *source, char const *obj)
{
    int i;

    for (i = 0; i < 6; i++) {
        if (*(source + i) == *obj) {
            return &(source + i); //l-value error here
        }
    };

    return NULL;
}

You can't take the address of an expression, only of a variable. Even if you could, you'd be returning a char** instead of a char*. Get rid of the & and you should be fine.

I got this error when the & is removed:

error C2440: 'return' : cannot convert from 'const char *' to 'char *'|

Right. Since source is a const char *, and the return value is based on that, you need to return a const char *.

How do I do that? It keeps giving me a syntax error. Do I need to introduce a new const pointer?

EDIT: Nope, doesn't work. I have no idea what to do.

The return value of your function is "char *". Change it to "const char *".

Many thanks!
