2.14 - Multiples

Objetive

Create a program to write on screen the numbers from 1 to 500 that are multiples of 3 and also multiples of 5 (hint: use the remainder of the division).

Solution


multiples 3 and 5
using System;
public class Exercise030
{
    public static void Main()
    {
        int i = 1;
        
        while ( i <= 500)
        {
            if ((i%3 == 0) && (i%5 == 0))
                Console.Write("{0} ",i);
                
            i++;
        }
    }
}

multiples 3 and 5 for
using System;
public class Exercise030
{
    public static void Main()
    {
        int i = 1;
                
        for (i=1; i <= 500; i++)
        {
            if ((i%3 == 0) && (i%5 == 0))
                Console.Write("{0} ",i);
        }
    }
}

multiples 3 and 5 for step 15
using System;
public class Exercise030
{
    public static void Main()
    {
        for (int i=15; i <= 500; i+=15)
            Console.Write("{0} ",i);
    }
}
