}

Here is the template function that works
#include <iostream>
#include <string>

using namespace std;

template <class Any>
void Add(Any a, Any b)
{
cout << a + b << endl;
}

void PauseIt()
{
cout << "enter any character and press Enter to exit"
<<endl;
char c;
cin >> c;
}

int main()
{
int a=3,b=5;
Add(a,b);
double c=2.3, d=4.3;
Add(c,d);
cout << " enter the first word ";

string x, y;
getline(cin,x);
cout << endl;
cout << "Enter the second word ";
getline(cin, y);
Add(x,y);
PauseIt();
}
