1). Simple Class Example Program In C++

Definition

The C++ programming language allows programmers to separate program-specific datatypes through the use of classes. Classes define types of data structures and the functions that operate on those data structures. Instances of these datatypes are known as objects and can contain member variables, constants, member functions, and overloaded operators defined by the programmer. 

Syntactically, classes are extensions of the C struct, which cannot contain functions or overloaded operators.

Class Syntax:

class classname {
Access - Specifier:
Member Varibale Declaration;
Member Function Declaration;
}

Example Program:

    Coded By:THIYAGARAAJ MP                             */

// Header Files
#include <iostream>
#include<conio.h>
using namespace std;

// Class Declaration
class person
{
//Access - Specifier
public:

//Varibale Declaration
  string name;
  int number;
};

//Main Function
int main()
{
    // Object Creation For Class
    person obj;

    //Get Input Values For Object Varibales
    cout<<"Enter the Name :";
    cin>>obj.name;

    cout<<"Enter the Number :";
    cin>>obj.number;

    //Show the Output
    cout << obj.name << ": " << obj.number << endl;

    getch();
    return 0;
}

Sample Output:

Enter the Name :Byron
Enter the Number :100
Byron: 100
