Dart Program – Product of Digits in a Number

Product of Digits in a Number using Dart

In the following program, we read a number from user via console, and find the products of digits in this number.

We use for loop to iterate over the digits of the number, and accumulate the product of the digits in result.

Refer Dart For Loop tutorial.

main.dart

import 'dart:io';

void main() {
  print('Enter N');
  int N = int.parse(stdin.readLineSync()!);

  int result = 1;
  for (int i = N; i > 0; i = (i / 10).floor()) {
    result *= (i % 10);
  }

  print('Product of digits\n$result');
}

Output

Enter N
12345
Product of digits
120

Summary

In this Dart Tutorial, we have written a Dart program to find the product of digits in given number.
