Answer 1

 int [] i = new int[] {1,2,3,4,5,6};
            foreach (int num in i)
            {
                if (num%2==0)
                {
                    Console.WriteLine(num);
                }
            }

why the output is = 2,4,6

 

The modulus operator % performs division but returns the remainder, not the
quotient as the division operator / does.

For the expression x % 2 any value of x which is evenly divisible by 2 will
return a remainder of zero.

Hi santosh,

You could look into the following tutorial about how modulus operation works.

What is modular arithmetic?

Modulus only returns value that is only divide by "x" (num%x), in your case 2 and remainder will be zero only to output those.

Example:

2÷2=1 and remainder is 0

4÷2=2 and remainder is 0

6÷2=3 and remainder is 0

So, you get output 2,4,6
