Pick the rightmost value of 12, i.e. Some of our partners may process your data as a part of their legitimate business interest without asking for consent. step 1: include the header files to use the built in functions files into the c program. Divide a given number by 10 Create a variable to store the reversed number, say it is rev and initialized it with 0. Run code output enter an integer: 2345 reversed number = 5432 this program takes integer input from the user. Feel free to put a comment if you find any problem or bugs. Here is the answer to this question: step 2: equate rev num with the obtained result. Multiply the variable reverse by 10 and add the remainder into it. The question is, write a program in C that reverse a number using for loop. #include <iostream> using namespace std; int main () { int n, reverse=0, rem; cout<<"Enter a number: "; #include<stdio.h> int main () { int n, reverse=0, rem; printf ("Enter a number: "); scanf ("%d", &n); rev = it will hold the integer value. I love coding and I regularly tries to practice it. Change 123 to 12. C program to reverse a number using function 4. Divide given number by 10 and find modulus. // Calling out user-defined function. C++ Program to Reverse a Number Using While Loop In this program, the compiler will ask the user to enter the number which the user wants to reverse a number. C program to reverse a number and c program to reverse a number using iterative approach reverse a string using stack in this program, i'll show how to reverse a number using recursion. Using Recursion 1. For example if user enter 423 as input then 324 is printed as output. You can check them and reuse them. Divide a given number by 10 To reverse a number in C, we used modulus (%). In the program, we use the modulus operator (%) to obtain digits of the number. Algorithm to C program to reverse a number recursively. getReversedNumber(1234) = (4*1000) + getReversedNumber(123) while(num > 0) { rev = rev*10 + num%10; num = num/10; } Eventually, rev stores the reverse number of that in num and the . main.c. Also num is divided by 10 in each loop iteration. To invert the number write its digits from right to left. #include < iostream > using namespace std; int main { int n; cout << " Enter a num: "; cin >> n; int reverse = 0, lastdigit; while (n > 0) { lastdigit = n % 10; In this way, we will have a rev variable that holds the reverse of given number (1234) That is, rev=4321; Now let's move on to the programs on reversing a number. Add the modulus and reverse number. Share on: Did you find this article helpful? Using for Loop 3.

To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. Logic of Reverse Number in C++ Modulus (%) sign is used to find the reverse of the given number. The reversed number is stored in the reverse named variable. 3, and add it to reverse. In each iteration, the remainder when the value of n is divided by 10 is calculated, reversed_number is computed and the value of n is decreased 10 fold. In this method, we will use a recursive function to apply the reverse number in which the function calls itself from its definition part. Method 2: Recursive program to reverse a number. while(num > 0) { temp = num%10; store the result in temp variable rev = (rev*10) temp; num = num 10; } explanation suppose, an input number is 243. while loop condition is true, as num is 243 rev = 0 * 10 3; num = 24;. Print the result of 4th step. log10(N) + 1 returns the number of digits in N. log10(N) is logarithm of N with base 10(log10(2311) + = 4). Writing reverse a number program in C can be done using various techniques but here in this program, we show how to write a c program to reverse digits in a number using while loop in a proper way.Happy coding. There are four ways to reverse a number in C, by using for loop, while loop, recursion, or by creating a function. Run Code Output Enter an integer: 2345 Reversed number = 5432 This program takes an integer input from the user and stores it in variable n. Then the while loop is iterated until n != 0 is false. Related Programming Tutorials: what is recursion? Finally we remove right most digits from number in number = number/10 statement. then the while loop is used until n != 0 is false ( 0 ). Step 1: declare the variable number,reverse step 2: initialize reverse= 0 step 3: while number>0 (a) reverse=reverse*10 number%10; reverse = reverse*10 num%10; (b) divide number by 10 step 4: return reverse example live demo. N%10 returns the least significant digit of N(354%10 = 4).

Reversing a Number Using While loop 2. given a singly linked list, write a java code to reverse a linked list. at the end of iteration, we end up with the reversed number in the result. Let getReversedNumber(N) is a function, which returns reverse of N. Then, we can use recursion to reverse the digits if a number using below mention recursive equation. Add the modulus and reverse number. This program first take an integer as input form user, then reverse its digits using modulus(%), division(/) and multiplication(*) operator inside loop. In this program, we are getting number as input from the user and reversing that number. Learn how to write a c Program to reverse a number. step 3: accept the number from the user and store it into ' num '. The consent submitted will only be used for data processing originating from this website. This program will read an integer positive number and reverse that number. Multiply the reverse number by 10. We use the modulo operator (%) in the program to get the digits of a number. this program will ask the user to input some like, comments, share and subscribe. Reverse a number: We can userecursion to reverse the digitsif a number because it follows recursive sub-problem property. To invert number look at it and write it from opposite direction or the output of code is a number obtained by writing original number from right to left. This program first take an integer as input form user, then reverse it's digits using modulus(%), division(/) and multiplication(*) operator inside loop. Reverse a Number in C using While Loop #include <stdio.h> int main() { int reversedNbr = 0, nbr; printf("Enter a number to reverse: "); scanf("%d", &nbr); Examples : Input : num = 12345 Output: 54321 Input : num = 876 Output: 678 Flowchart: ITERATIVE WAY Algorithm: Step-3 - Now find all the possible proper divisors of the original number and calculate the sum of it. After reversing it prints the reversed number. Since there are many ways to create a C++ program to reverse a number, therefore we've used some famous method to do the task as given below: Reverse a Number using while Loop using for Loop Algorithm. c program in the following program, we read a number to n from user via console input, and reverse this number. C Program to Print Even Numbers from 1 to N .

Step 1: Multiply the rev_num with 10 and add the digit which we extracted from the input. Let's see a simple c example to reverse a given number. Inside the loop, create a variable say rem to hold the unit digit of number n. Set, rem = n%10. After 4 iterations, rev_num contains 5432 which is our required result. This program used while loop, we can similarly use for loop. Manage SettingsContinue with Recommended Cookies. For Example input number is 1234 after reversing number will be 4321. We will declare two int variables: number store the number to be reversed, and reversed number, initialized to be 0, will hold the resultant reversed number. The logic for a reverse number is as follows: Initialize a reverse number to 0. let's first understand, what is recursion. !#reversenumber #clanguage#cprogramming. Repeat this process till number is greater than zero.
