provide some relevant stuff with some examples as well

Well, let's say you have -5 % 3;
Java and C would give -2. (Negative remainder of 5/3)
Python, on the other hand, would give 1. (Python adds 3 until the answer is positive).
Let's say 13 % -2, on the other hand.
Java and C would give you 1 (13 % 2. They ignore negative denominators.)
Python, however, would give you -1. (Negative remainder of 13 / 2. Basically, Python keeps subtracting 2 until the number is negative.)
Hope this is clear and it helped. 😉
(No idea why I talked about Java here, but just in case anyone wants to know. 😉)

The modulo operator takes the remainder of a division between two numbers.
For example, 11 % 3 = 2, because the remainder of 11/3 is 2.
(Or at least, I assume the % operator is the modulo operator in C, because I don't know C. 😉 But that's the way it operates in literally every programming language I know, so it should be that way.)

Actually, % in C(++) and python are different
For example, take -8 % 5
In python this would print 2,
in C(++) this would print -3.
In python % is implemented as mod,
meaning -8 + 5 * 2 = 2
in C(++) % is implemented as the remainder
-8 / 5 = -1 with a remainder of -3
For positive numbers these don't make a difference, but you should be aware of this when dealing with negative numbers.
Edit:
Wrote this before the actual negative question popped up ^^

guys what if either numerator or denominator is negative? will c or python gives the same answer or different. just check it once.
example:
2%3=2
what if numerator or denominator is negative
