So I was reading about auto and other C++11 std feature and made this program:
#include<iostream>
#include<tuple>
using namespace std;
template<typename T1, typename T2>
auto create_pair(const T1 &a, const T2 &b)
{
pair<T1, T2> p(a, b);
return p;
}
int main()
{
auto p1 = create_pair(4, 5.6);
pair<int, float> p(p1);
cout << get<0>(p);
cout << endl;
cout << get<1>(p);
return 0;
}
My question is whether auto
can be used in the way prescribed here in the create_pair()
function or there exists some other workaround this to achieve the same result.
The error message when compiled with gcc is this:
create_pair function uses auto type specifier without return type.
