void change(int a, int b)

{

int k; k=a; a=b; b=k;

cout <<“\n In function change () “;

cout<<“\n Values X=”<<a <<“ and Y= “<<b;

cout<<“\n Address X=”<<(unsigned)&a <<“ and Y= “<<(unsigned)&b;

}

OUTPUT:

Enter Values of X & Y :5 4

In function change()

Values X=4 and Y= 5

Address X=4090 and Y= 4092

In function main()

Values X=5 and Y= 4

Address X=4096 and Y= 4094

Explanation

In the above program, we are passing values of actual arguments x and y to function change(). The

formal arguments a and b of function change() receive these values. The values are exchanged

i.e., value of a is assigned to b and vice versa.
