Returning pointers to strings

Let’s declare two strings in a function:

char* func()
{
    char str1[]   = "Hello";
    char str2[16] = "World";

    return str1; //return str2;
}

Both str1 and str2 are local variables of func. They get allocated when the function starts executing. Their stack frame is invalidated when the function finishes. Therefore, their memory gets marked ...
