Question

I have this block of code:

int myFunc( std::string &value )
{
    char buffer[fileSize];
    ....
    buffer[bytesRead] = NULL;
    value = buffer;
    return 0;
}

The line – buffer[bytes] = NULL is giving me a warning: converting to non-pointer type ‘char’ from NULL. How do I get rid of this warning?

Don’t use NULL? It’s generally reserved for pointers, and you don’t have a pointer, only a simple char. Just use \0 (null-terminator) or a simple 0.
