What is Class and Objects in C++?

  • The classes are the most important feature of C++ that leads to Object Oriented programming.
  • Class is a user defined data type, which holds its own data members and member functions, which can be accessed and used by creating instance of that class.
  • The variables inside class definition are called as data members and the functions are called member functions.
  • Class is just a blue print, which declares and defines characteristics and behavior, namely data members and member functions respectively. And all objects of this class will share these characteristics and behavior.
  • Objects are instances of class, which holds the data variables declared in class and the member functions work on these class objects.
  • Each object has different data variables. Objects are initialized using special class functions called Constructors.

Below is the source code for C++ Program to Multiply every member by k using class which is successfully compiled and run on Windows System to produce desired output as shown below :

 
 

SOURCE CODE : :

/* C++ Program to Multiply every member by k using class  */

#include<iostream>
using namespace std;

class array
{
     public:
         int n;
         void readarray();
         void multiply();
};

void array::readarray()
{
        int a[100];
        cout<<"Enter No. of elements u want :: ";
        cin>>n;
        for(int i=0;i<n;i++)
    {
        cout<<"\nEnter [ "<<i+1<<" ] element :: ";
        cin>>a[i];
    }

}

void array::multiply()
{
        int i,j,a[100],temp[100],k;

        cout<<"\nEnter the no. which u want to multiply :: ";
        cin>>k;

        for(i=0;i<n;i++)
        {
                for(j=0;j<n;j++)
                temp[i]=(a[i]*k);
        }
        cout<<"\nAfter Multiply every member by k = [ "<<k<<" ], Resultant array is :: "<<endl;
        for(int i=0;i<n;i++)
    {
        cout<<"\n [ "<<i+1<<" ] element :: "<<temp[i]<<"\n";
    }

}

int main()
{
        array mul;

        mul.readarray();
        mul.multiply();

        return 0;
}

OUTPUT : :

/* C++ Program to Multiply every member by k using class  */

Enter No. of elements u want :: 6

Enter [ 1 ] element :: 1

Enter [ 2 ] element :: 2

Enter [ 3 ] element :: 3

Enter [ 4 ] element :: 4

Enter [ 5 ] element :: 5

Enter [ 6 ] element :: 6

Enter the no. which u want to multiply :: 5

After Multiply every member by k = [ 5 ], Resultant array is ::

 [ 1 ] element :: 5

 [ 2 ] element :: 10

 [ 3 ] element :: 15

 [ 4 ] element :: 20

 [ 5 ] element :: 25

 [ 6 ] element :: 30

Process returned 0

Above is the source code and output for C++ Program to Multiply every member by k using class which is successfully compiled and run on Windows System to produce desired output.
