In this tutorial learn how you can input two numbers from keyboard and store it in two variable A and B and swap the values. Here the trick is so simple that we use a third variable.

First, we store the value of A to C the third variable. And then we store the value of B to A. And finally, we store the value of C to B. By this we swapped the values.

C programming is a powerful general-purpose programming language. It can be used to develop software like operating systems, databases, compilers, etc.

Write a Program to Swap the Values of Two Numbers from Keyboard

Here is the code to input two numbers from keyboard and store it in two variable A and B and swap the values in C programming.

#include <stdio.h> //WAP to input two numbers from keyboard, store it in two variable A and B . Swap the values. 
int main(){
    int A,B,C;
    printf("Enter 2 numbers:");
    scanf("%d%d",&A,&B);
    C=B;
    B=A;
    A=C;
    printf("Swapped values of A is %d and B is %d.",A,B);
    return 0;
}
