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 build Simple calculator using Class template which is successfully compiled and run on Windows System to produce desired output as shown below :

SOURCE CODE : :

/* C++ Program to build Simple calculator using Class template  */

#include <iostream>
using namespace std;

template <class T>
class Calculator
{
private:
        T num1, num2;
        
public:
        Calculator(T n1, T n2)
        {
                num1 = n1;
                num2 = n2;
        }
        
        void displayResult()
        {
                cout << "Numbers are: " << num1 << " and " << num2 << "." << endl;
                cout << "Addition is: " << add() << endl;
                cout << "Subtraction is: " << subtract() << endl;
                cout << "Product is: " << multiply() << endl;
                cout << "Division is: " << divide() << endl;
        }
        
        T add() { return num1 + num2; }
        
        T subtract() { return num1 - num2; }
        
        T multiply() { return num1 * num2; }
        
        T divide() { return num1 / num2; }
};

int main()
{
        Calculator<int> intCalc(2, 1);
        Calculator<float> floatCalc(2.4, 1.2);
        
        cout << "Int results:" << endl;
        intCalc.displayResult();
        
        cout << endl << "Float results:" << endl;
        floatCalc.displayResult();
        
        return 0;
}

OUTPUT : :

/* C++ Program to build Simple calculator using Class template  */

Int results:
Numbers are: 2 and 1.
Addition is: 3
Subtraction is: 1
Product is: 2
Division is: 2

Float results:
Numbers are: 2.4 and 1.2.
Addition is: 3.6
Subtraction is: 1.2
Product is: 2.88
Division is: 2
 
Exit code: 0 (normal program termination)

Above is the source code and output for C++ Program to build Simple calculator using Class template which is successfully compiled and run on Windows System to produce desired output.
