Template

#include <iostream>
using namespace std;
template <class T>
T add(T x, T y)
{
    T result;
    result = x+y;
    return result;
}

template <class T>
T sub(T x, T y)
{
    T result;
    result = x-y;
    return result;
}

template <class T>
T mul(T x, T y)
{
    T result;
    result = x*y;
    return result;
}

template <class T>

    T result;
    result = x/y;
    return result;
}

int main()
{
    int a,b;
    a=7;
    b=5;
    cout<<add(a,b)<<endl;
    cout<<sub(a,b)<<endl;
    cout<<mul(a,b)<<endl;
    cout<<divi(a,b)<<endl;
    system("pause");
    return 0;
