I don't understand why (==) is use instead of (!=) And why is (%) is used instead. Please explain it for me. Code in description

Question

#include <iostream>
using namespace std;

int main() {
int number;
cin>>number;
// your code goes here
if (number %2==0){
cout << "even";
}
else {
cout <<"odd";
}
return 0;
}

Answer 1

This is the definition of an even number. If a number is divisible by 2 without a remainder, it is an even number. % is a division operator with a remainder.

Answer 2

Just to add a bit more Alexey's statement..

% is a modulo operator. The result is the remainder from the division.

ie:

15 % 12 = 3

15 / 12 = 1.25

15 % 12 is derived by:
15 / 12 = 1 with 3 left over from long division.

Answer 3

Thank you
