C Program to Swap Two Numbers

In this article, we will discuss how to write a C program to swap two number using a temporary variable and also without using a temporary or third variable.

For this C Program to Swap Two Numbers purpose, we are going to use Pointers, Functions, Arithmetic Operators, Bitwise Operators, Call By Reference in C concepts.

This C program allows the user to enter two integer values. Using the third variable, this C program Swap two numbers.

Source Code:

/* C Program to Swap Two Numbers */

#include 

int main()
{
  int a, b, Temp;
 
  printf("\nPlease Enter the value of a and b\n");
  scanf("%d %d", &a, &b);
 
  printf("\nBefore Swap: a = %d and b = %d\n", a, b);
 
  Temp = a;
  a    = b;
  b    = Temp;
 
  printf("\nAfter Swapping: a = %d and b = %d\n", a, b);
 
  return 0;
}

Output Console:

Analysis:

Within this C Program to Swap Two Numbers, we assigned a = 6 and b = 13

Temp = a – it means assigning the a value to the Temp variable
Temp = 6

a = b – it means assigning the b value to the variable a
a = 13

b = Temp – it means assigning the Temp value to the variable b
b = 6
Last Printf statement will print the a, b values as output.
