Answer 1

#include <iostream> template< typename T1, typename T2 > struct is_same_type { enum { result = false }; }; template< typename T> struct is_same_type<T,T> { enum { result = true }; }; int main() { std::cout << is_same_type<int,float>::result << '\n' << is_same_type<char,char>::result << '\n'; return 0; }
