First get the input from the user then using call by value function pass the value with three variable we performing swap process in object oriented programming .

Source code call by value swap programming algorithm in c c++

#include<iostream.h>

#include<conio.h>

void swap(int x,int y)

{

int temp;

temp=x;

x=y;

y=temp;

cout<<"\n The value of a and b in swap fun is\t "<<x<<"\t"<<y;

}

void main()

{

int a,b;

clrscr();

cout<<"\n Enter the value of a and b:\n";

cin>>a>>b;

cout<<"\n The value of a and b before the swap fun is:\t"<<a<<"\t"<<b;

swap(a,b);

cout<<"\n\n The value of a and b after the swap fun is:\t"<<a<<"\t"<<b;

getch();

}

OUTPUT swap fucniton call by value in c++ programming

Enter the value of a and b:

7

2

The value of a and b before the swap fun is: 7 2

The value of a and b in swap fun is: 2 7

The value of a and b after the swap fun is: 7
