What will be the output of the following C++ code?

#include <iostream>
using namespace std;
template<typename type>
class TestVirt
{
    public:
    virtual type TestFunct(type Var1)
    {
        return Var1 * 2;
    }
};
int main()
{
    TestVirt<int> Var1;
    cout << Var1.TestFunct(100) << endl;
    return 0;
}
