Templates are the foundation of generic programming, which involves writing code in a way that is independent of any particular type.

 
 

A template is a blueprint or formula for creating a generic class or a function. The library containers like iterators and algorithms are examples of generic programming and have been developed using template concept.

There is a single definition of each container, such as vector, but we can define many different kinds of vectors for example, vector <int> or vector <string>..

Function Template :

The general form of a template function definition is shown here:

 

template <class type> ret-type func-name(parameter list)

{
// body of function
}

Class Template :

Just as we can define function templates, we can also define class templates. The general form of a generic class declaration is shown here:

template <class type> class class-name

{
.
.
.
}

Below is the source code for C++ program to find Sum of numbers using Overload template function which is successfully compiled and run on Windows System to produce desired output as shown below :

SOURCE CODE : :

/* C++ program to find Sum of numbers using Overload template function  */

#include <iostream>
using namespace std;

template<class t1>
void sum(t1 a,t1 b,t1 c)
{
    cout<<"\nTemplate function 1: Sum = "<<a+b+c<<endl;
}

template <class t1,class t2>
void sum(t1 a,t1 b,t2 c)
{
    cout<<"\nTemplate function 2: Sum = "<<a+b+c<<endl;
}

void sum(int a,int b)
{
    cout<<"\nNormal function: Sum = "<<a+b<<endl;
}

int main()
{
    int a,b;
    float x,y,z;
    cout<<"\nEnter two integer data: ";
    cin>>a>>b;
    cout<<"\nEnter three float data: ";
    cin>>x>>y>>z;
    sum(x,y,z); // calls first template function
    sum(a,b,z); // calls first template function
    sum(a,b); // calls normal function
    return 0;
}

OUTPUT : :

/* C++ program to find Sum of numbers using Overload template function  */

Enter two integer data: 4
5

Enter three float data: 3.4
2.3
6.5

Template function 1: Sum = 12.2

Template function 2: Sum = 15.5

Normal function: Sum = 9

Process returned 0

Above is the source code and output for C++ program to find Sum of numbers using Overload template function which is successfully compiled and run on Windows System to produce desired output.
