C/C++ Program to write a function that will interchange the value of two variable, Program to interchange values of  2 variables

Program

#include<stdio.h>

#include<conio.h>

void interchange(int, int);

void main()

{

int x,y;

clrscr();

printf("Enter two Numbers:\n");

scanf("%d %d", &x, &y);

printf("\nOriginal value is:%d %d", x,y);

interchange(x,y);

getch();

}

void interchange(int m,int n)

{

int temp;

temp=m;

m=n;

n=temp;

printf("\nThe value after interchange is: %d %d",m,n);

}

Changes for C++

If you want to write the same program in c++ apply the following changes to the program.

1.) change the header file from "#include<stdio.h>" to "#include<iostream>.h" 

2.)  for input & output use "cout<<" & "cin>>" instead of "printf" & "scanf".

3.) don't use "% "symbol and "&" sign in "cin>>" statement.
