What does the '%' operator mean?

Question

I have next code

int a,b,c;
b=1;
c=36;
a=b%c;

What does \"%\" operator mean?

Answer 1

% is the remainder operator in many C-inspired languages.

3 % 2 == 1
789 % 10 = 9

It's a bit tricky with negative numbers. In e.g. Java and C#, the result has the same sign as the dividend:

-1 % 2 == -1

In e.g. C++ this is implementation defined.
