reverse number Program in C

C Program to reverse number

In this Program we will using loop and arithmetic operators and make a Program to reverse Integer Numbers. First, we will getting number as input from the user and reversing that number.

Lets Understand Program Steps

1. #include<stdio.h>  
2. #include<conio.h>  
3. main()  
4. {  
5. int n, reverse=0, rem;  
6. clrscr();  
7. printf("Enter a number: ");  
8.   scanf("%d", &n);  
9.   while(n!=0)  
10.   {  
11.      rem=n%10;  
12.      reverse=reverse*10+rem;  
13.      n/=10;  
14.   }  
15.   printf("Reversed Number: %d",reverse);  
16. getch();  
17. }  

Output:

Enter a number: 123
Reversed Number: 321
