Program to calculate product of digits of a number

Last Updated: 17-05-2019

Given a number, the task is to find the product of the digits of a number.

Examples:

Input: n = 4513 Output: 60 Input: n = 5249 Output: 360

Recommended: Please try your approach on {IDE} first, before moving on to the solution.

General Algorithm for product of digits in a given number:

Get the number

Declare a variable to store the product and set it to 1

Repeat the next two steps till the number is not 0

Get the rightmost digit of the number with help of remainder ‘%’ operator by dividing it with 10 and multiply it with product.

Divide the number by 10 with help of ‘/’ operator

Print or return the product

Below is the solution to get the product of the digits:

C++

// cpp program to compute

// product of digits in the number.

#include<bits/stdc++.h>

using namespace std;

  

/* Function to get product of digits */

int getProduct(int n)

{

    int product = 1;

  

    while (n != 0) 

    {

        product = product * (n % 10);

        n = n / 10;

    }

  

    return product;

}

  

// Driver program

int main()

{

    int n = 4513;

    cout << (getProduct(n));

}
