What will be the result of calling the h() function in the following C++ code?
const char* upwork[] = { "Freelancers", "Projects", "Fixed", "Hourly" }
const char* f(int i) { return upwork[i]; }
void g(string s){}
void h()
{
const string& r = f(0);
g(f(1));
string s = f(2);
cout << "f(3): " << f(3) << " s: " << s << " r: " << r <<
