Question

I need to write a boolean expression that checks for given integer if it can be divided by 7 and 5 in the same time (without remainder) in C#.

Examples:

n	Divided by 7 and 5?
3	false
0	false
5	false
7	false
35	true
140	true

 

Answer 1

the answer:

using System;

class DivideBySevenAndFive
{
    static void Main()
    {
        Console.WriteLine("Please enter your number:");
        double n = double.Parse(Console.ReadLine());

        bool result = (n % 5 == 0) && (n % 7 == 0);
        Console.WriteLine("The number {0} can be divided by 5 and 7? ANSWER: {1}",n, result);
    }
}

Answer 2

My answer:

using System;

class DivideBy7And5
{
    static void Main()
    {
        Console.WriteLine("Enter integer number:");
        int numInt = int.Parse(Console.ReadLine());
        bool checkNum7 = (numInt % 7) == 0;
        bool checkNum5 = (numInt % 5) == 0;
        if (numInt == 0)
        {
            checkNum7 = false;
        }
        Console.WriteLine("Divided by 7 and 5? {0}", checkNum7 && checkNum5);
    }
}
