C Program to swap two numbers with temporary variable - My CS Tutorial

In this post we will learn how to write a C program that swap two numbers with temp variable.Given two numbers and swap these numbers in this program with using 3rd (temporary) variable.

Solution

• In this program we will use three variables as a, b and c for two numbers swapping.
• We will use integer data type in this program.
• We will use some logics as:-

         c = a;
         a = b;
         b = c;

• After it we will print the numbers using printf statements.

Example:-

Input firstnumber=35
Input secondnumber=53

After swapping

Output firstnumber=53
Output secondnumber=35

C program code

#include<stdio.h>
#include<conio.h>
void main()
{
 int a,b,c;
 printf("\n Enter the first number: ");
 scanf("%d",&a);
 printf("\n Enter the second number: ");
 scanf("%d",&b);
 printf("\n The values of a is %d 
     and b is %d before swaping\n",a,b);
 c=a;
 a=b;
 b=c;
 printf("\n The values of a is %d
       and b is %d after swaping\n",a,b);
 getch();                           
                                
}

OUTPUT 1:

OUTPUT 2:

In first output,the value of input first and second number is 35 and 53
After swapping
The value of first number 53 and second number 35

In second output,the value of input first and second number is 25 and 32
After swapping
The value of first number 32 and second number 25
