Display Multiples of Both 3 and 5 in C#

In this exercise, you'll create a C# program that displays all numbers between 1 and 500 that are divisible by both 3 and 5. This task helps practice the use of loops and the modulo operator (%), which checks whether a number is divisible by another without a remainder. The program will iterate through the range from 1 to 500, checking each number to see if it meets the divisibility condition, and display only the numbers that satisfy the criteria.

Objective

The objective of this exercise is to write a C# program to display on the screen the numbers from 1 to 500 that are multiples of both 3 and 5. (Hint: Use the modulo operator to check for divisibility by both 3 and 5.)

Example C# Exercise

 Copy C# Code 
// First and Last Name: John Doe

using System;

namespace MultiplesOfThreeAndFive
{
    class Program
    {
        // Main method to execute the program
        static void Main(string[] args)
        {
            // Iterate through numbers from 1 to 500
            for (int i = 1; i <= 500; i++)
            {
                // Check if the number is divisible by both 3 and 5
                if (i % 3 == 0 && i % 5 == 0)
                {
                    // If divisible by both, display the number
                    Console.WriteLine(i);
                }
            }
        }
    }
}
