program to demonstrate Call by Value and Call by Reference (C++)

Aim: Write a program to demonstrate Call by Value and Call by Reference

Ans.

#include<iostream.h>

Void<<”Initial Value\nA=”<<a<<”& B=”<<endl;

a=a+b;

b=a-b;

a=a-b;

cout<<”Final Value\nA =”<<a<<”& B = “<<b<<endl;

}

Void main()

{

Int m=8, n=12;

Cout<<”Initial value\nM=”<<m<<”& N=”<<n<<endl;

Swap(m,n);

Cout<<”\nFinal Value\nM = “<<m<<” & N= “<<n<<endl;

}
