Please help with a class construction

Hi guys,
I am a beginner in C++, but I've got to implement as simple a class as possible to pass the test case below:

Code:

#include <iostream>
#include <string>
#include <assert.h>
class cVarCont
{
public:
	template <class T>
	void manage(const std::string& name, T& varRef)
	{
	}

public:
	void setValue(const std::string& namedVariable, const std::string& value)
	{
	}
};
int main()
{
	cVarCont nvc;
	int myInt(0);
	double myDouble(0.);
	std::string myString("");

	nvc.manage("int", myInt);
	nvc.manage("dbl", myDouble);
	nvc.manage("str", myString);

	nvc.setValue("int", "43");
	nvc.setValue("dbl", "123.8");
	nvc.setValue("str", "hello");

	std::cout << myInt << std::endl;
	std::cout << myDouble << std::endl;
	std::cout << myString << std::endl;
	std::cout<<"Hello World\n";

	assert(myInt==43);
	assert(myDouble==123.8);
	assert(myString=="hello");
	return 0;
}

And do not use a void pointer.
I appreciate any hints on this.
Thanks.
