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

{
.
.
.
}

SOURCE CODE : :

/* C++ Program to Perform Simple Addition Function Using Templates  */

#include <iostream>
#include <stdio.h>

using namespace std;

template <class type> type add(type num1, type num2);

int main ()
{
  std::cout << "Please enter integer 1 : ";
  int num1;
  cin >> num1;

  cout << "\nPlease enter integer 2 : ";
  int num2;
  cin >> num2;

   int answer = add(num1, num2);
   cout << "\nThe sum of [ " << num1 << " + " << num2 << " ] = " << answer<<"\n";

   getchar();

    return 0;
}
template <class type> type add(type num1, type num2)
{
    type result = num1 + num2;
  return result;
}

---

OUTPUT : :

---

/* C++ Program to Perform Simple Addition Function Using Templates  */

Please enter integer 1 : 12

Please enter integer 2 : 34

The sum of [ 12 + 34 ] = 46

Process returned 0
