char* test(char* path) {
    ifstream f(string(path));
    string str(istreambuf_iterator<char>(f), istreambuf_iterator<char>());
    return str.c_str();
}

This code cannot be compiled at visual studio 2012.

Error is

error C2228: left of '.c_str' must have class/struct/union

What is the problem? Any suggestion?

As a side note you're returning a pointer to a local variable which will go out of scope. – Retired Ninja Jun 24 '14 at 08:34
