I did not understand modulus operator. Please explain

Question

I couldn't understand how the remainder is left behind and why % sign is used

Answer 1

Modulus is kinda like division but insted of giving you have many time something can be divided, it gives you "what is left" (the remainder) after the division.

4/2 = 2
4%2 = 0

4/3 = 1,333333......
4%3 = 1

15/7 = 2,1428.........
15%7 = 1

Answer 2

How come 4%2=0

What % represent ??

Answer 3

% is the "modulus" operator, just like + - / * Are operators, and the modulus calculation result is the the "remainder"

it works just like division.
but results in what is left aften the division

5/2 = 2.xxx
5%2 = 1

6/2 = 3
6%2 = 0

4/2 = 2
4%2 = 0
