In this C program to reverse a number using function, we defined a function findReverse() which return type is int and takes an int argument. Inside the findReverse() function sum is declared and initialized with value 0.

Jul 17, 2023 · In this article, we will learn how to reverse the digits of a number in C programming language. For example, if number num = 12548, the reverse of number num is 84521. (a) Multiply rev_num by 10 and add remainder of num. divide by 10 to rev_num. rev_num = rev_num*10 + num%10; . (b) Divide num by 10.

This program takes integer input from the user. Then the while loop is used until n != 0 is false (0). In each iteration of the loop, the remainder when n is divided by 10 is calculated and the value of n is reduced by 10 times. Inside the loop, the reversed number is computed using: reverse = reverse * 10 + remainder;

Nov 7, 2021 · We use the modulo operator (%) in the program to get the digits of a number. There are four ways to reverse a number in C, by using for loop, while loop, recursion, or by creating a function. Output:

May 19, 2024 · In this article, we will learn how to write a C program to reverse a number. For example, if the given number is 1234 then program should return number 4321 as output. We will see two different ways to accomplish this. In this program, we are using a recursive function reverse_function to reverse a user entered number.

Apr 12, 2025 · C Program to Reverse a Number Using Function. Here, we will create a function in the main method and use the algorithm inside it to calculate the reverse of the number entered by the user. Example. #include <stdio.h> int rev_Int(int); int main(){ int Num, Rev = 0; printf("\nEnter the number to reverse: "); scanf("%d", &Num);

We can use functions (much like the reverse function before) in the C program to reverse a number. The function body will enclose the logic you want to use to reverse the function. You can then call the function passing the number you want to reverse as argument.

Reverse a Number in C means moving the digit at the last position to the first position and vice versa. For example, if the given number is “1234”, the reverse number will be “4321”. There are several ways to reverse a number in C language. Let’s take a detailed look at all the approaches to reverse a number.

Question: Write a program in C to find reverse of a given integer number using recursive function (recursion). result = reverse(number, 0); printf("Reverse of %d is %d.", number, result); return 0; } int reverse(int num, int rev) { if(num ==0) return rev; else return reverse (num /10, rev *10 + num %10); } Reverse of 1234 is 4321.

This article discloses how to write a C Program to Reverse a Number using the While Loop, for loop, Functions & Recursion with examples.
