Multiply every member by k using class
Write a C++ Program to Multiply every member by k using class. Here’s a Simple Program to Multiply every member by k using class in C++ Programming Language.
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.

Thanks for reading the post….
wrong progran
please write correct program in comment!
#include <stdio.h>
#include <iostream>
#include <string>
#include <vector>
#include <cmath>
using namespace std;
class Array{
private:
int arr[100];
int size;
public:
void input();
void mult();
};
void Array::input(){
int i;
cout<<“Enter the size of the array: “;
cin>>size;
for(i=0;i<size;i++){
cout<<“Enter the arr[“<<i<<“] element : “;
cin>>arr[i];
}
}
void Array::mult(){
int k;
cout<<“Enter the number you wish to multiply the element with : “;
cin>>k;
int i, temp[100];
for(i=0;i<size;i++){
temp[i]=arr[i]*k;
}
for(i=0;i<size;i++){
cout<<“The new array is :”<<temp[i]<<endl;
}
}
int main()
{
Array mul;
mul.input();
mul.mult();
return 0;
}
Enter the size of the array: 3
Enter the arr[0] element : 2
Enter the arr[1] element : 3
Enter the arr[2] element : 1
Enter the number you wish to multiply the element with : 2
The new array is :4
The new array is :6
The new array is :2
