Modulus understand even more.

[Love236]

Hello, i know how to use modulus but i dont understand what a part of this code means:

a % 2 == 0

what does 2 == 0 means? why is there a zero over there? and why is there a == there?

Thanks!

It checks if the remainder returned by a%2 is equal to 0. In particular this identifies even numbers.

Dont exactly understand, can you give me an example? thanks!

[Return 0]

The modulus operator returns the remainder of the division. So for example if a = 8; 8 / 2 = 4 with no remainder. So 8 % 2 = 0. So your condition:

if ( a % 2 == 0 )
     cout << a << " is an even number. " << endl;

'==' checks if the things on either side of it are equal. If they are it returns true, else it returns false.
