I try to run my C++ code in Visual Studio 2013.
The code was running in the past the gcc 4.9
I don't know why the code is in Visual Studio not running.
I upload the code to GitHub so that everyone can take a look at it. Please help me. I really don't know why the code is not running in Visual Studio.

Answer 1

Like Praetorian wrote, Template Classes can not be easiely splited into Header (.h) and Source (.cpp) Files. The reason is that "the compiler creates a new class with the given template argument." quote
My Solution to split Template Classes into Header (.h) and Source (.cpp) Files looks like this:
// HEADER File test.h
#ifndef __TEST_FH__
#define __TEST_FH__
template<typename T>
class test {
public:
T object;
test();
~test();
};
#include "test.cpp"
#endif
// SOURCE File test.cpp
#ifdef __TEST_FH__
#ifndef __TEST_SOURCE_FH__
#define __TEST_SOURCE_FH__
template<typename T>
test::test() {
//code
}
template<typename T>
test::~test() {
//code
}
#endif
#endif
Once more thank you very much Praetorian.
