In this tutorial you will learn about the C Program to Add reversed number with Original Number and its application with practical example.
In this tutorial, we will learn to create a C program that add reversed number with Original number using C programming.
Prerequisites
Before starting with this tutorial we assume that you are best aware of the following C programming topics:
- Operators.
- loop statements.
- While loop.
- Basic input/output operations.
C Program to Add reversed number with Original Number.
In this program first of all we reverse a number and that number will be added to original number. For example, user input number 321, the reverse number will be 123.and we add 321 to 123 => 321+123 = 444. Let see the code for that.

#include <stdio.h> int main() { int no, rev = 0,sum=0,temp; // declaring variables printf("Enter a number to reverse\n"); scanf("%d", &no); // taking number from user. temp=no; while (no != 0) // iterate till number became zero { rev = rev * 10; rev = rev + no%10; //reversing the value no = no/10; } printf("Reverse of the number = %d\n",rev); //printing reverse number sum=temp+rev; // adding them printf("sum of original + rev is number = %d",sum); printing original and rev number return 0; } |
Output
In the above program, we have first declared and initialized a set variables required in the program.
- no= take number from user.
- rev = it will hold reverse value.
- temp= it will hold original .
- sum= add original and reverse number.
In the next statement user will be prompted to enter a number into variable no. In our program, we use the modulus (%)operator to obtain digits.
How reversing a number is defined by the following steps:
- 1: START.
- 2:Take a number from user.
- 3: SET temp =no, sum =0.
- 4: REPEAT while (no != 0)
- 5: rev = rev * 10
- 6:rev = rev + no%10
- 7:no = no/10
- 8: sum = no+ temp
- 9: Print Sum
- 10: END.
First of all we take a number from user in variable no. and pass this number to temp variable after that in while loop we reverse the number as show in below image.
After reversing a number we add the reverse and temp variable.
As you can see how the number is reversing in following steps after the reversing number we add original number sum=temp+rev with reverse number to get required output and print the final value stored in sum variable.
