My problem is easy and I think the solution is obvious but I couldn't figure it out (even after googling).

I want to create a std::map containing many differents objects (int, char, ...) so I thought about telmplate.

#include "stdafx.h"
#include<iostream>
#include <map>

 using namespace std;


 template<typename T>
 std::map <std::string, T> myMap;
...

When I compile I have this error

error C2133: 'myMap' : unknown size
error C2998: std::map<std::string,T> myMap' : cannot be a template definition

So how to resolve that !!

Thank you

You cannot use a type placeholder in a variable definition. You always have to specify a type. – kiloalphaindia May 09 '18 at 16:40
Can you give a little more detail about, waht you are trying to achive? – kiloalphaindia May 09 '18 at 16:41
@kiloalphaindia : I want to insert into my Map let's say strings as first and sometimes integers smetimes strings as seconds – Blood-HaZaRd May 09 '18 at 16:43

`std::map` or `std::map>` ? – Jarod42 May 09 '18 at 17:12
Warning: This can turn into a book-keeping nightmare. Be honest with yourself on why you need to have this and exhaust more than a few alternatives before going with it. – user4581301 May 09 '18 at 17:14
