What does % as math operator in C++?

Question

Example: a = 16 % 3;

Answer 1

% 👈🏻 this is a modulus operator and we use this operator for getting the remainder when we divide two numbers

When 16 gets divided by 3 we get quotient 5 and remainder as : 1

So when we print : cout<< 16%3;

We get 1 (which is a remainder) as output

Answer 2

Hi! The operator of the remainder of the number %

(for example: 17 % 3 = 2)

1. Take the nearest number when divided by 3 would be zero. That's apparently 15
2. Subtract 15 from 17 and the result is your answer.
