Write a program to exchange the value of two variables?

Answer 1

#include<stdio.h>

void main()

{

int a,b,t;

printf("enter the values of two varaible");

scanf("%d%d",&a,&b);

t=a;

a=b;

b=t;

printf("the exchanged values are",b,a);

}

Answer 2

Swapping variables is accomplished using a temporary variable. For example, if A and B are integers, you can swap their values using the following code:

// Initialize A and B

int A = 5;

int B = 7;

// Create our temporary variable

int temp;

// Perform the swap

temp = A;

A = B;

B = temp;

// Print the results

cout << "A: " << A << " B: " << B << endl;

#include<conio.h>

void main()

{

int a,b,temp;

clrscr();

printf("\nEnter the value for a & b");

scanf("d",&a,&b);

temp=a;

a=b;

b=temp;

printf("\na=%d",a);

printf("\nb=%d",b);

getch();

}

Answer 3

#include<stdio.h> #include<conio.h> void main() { int a,b,c; printf("Enter the value of A"); scanf("%d",&a); printf("Enter the value of B"); scanf("%d",&b); c=a; a=b; b=c; printf("The value of A is %d",a); printf("The value of B is %d",b); getch(); }
