Modulus

[Hardy &&&]

I know that any number % 10 = zero.
Can any body give me the answer to C++ beginner?
what's result of:
2%500.
Thank you all.

Sure? Try out the following program:

#include <iostream>

int main()
{
std::cout << "1 % 10 == " << 1 % 10 << "\n";
return 0;
}

You can get an idea by trying out the following program.

#include <iostream>

int main()
{
std::cout << "2 % 500 == " << 2 % 500 << "\n";
return 0;
}

% operator gives remainder, so N % 10 != 0 always unless N is a
multiple of 10.

cout << "2%500=" << 2%500 << endl;

n mod 10 is not zero, contrary to what you thought.

As long as n and m are both positive, as in n % m, C obeys the rules
described in Wikipedia.

(1) Divide 2 by 500, and round your answer down to the nearest integer.

(2) Take that integer, and multiply it by 500.

(3) Subtract the result from 2.
That's your answer.

No it's not. For any positive n, n % 10 == 0 if n is a multiple of 10,
n/10 + r otherwise (r is the remainder and / is integer division). For 0
< n < 10 the remainder is simply n and for n == 0 the answer is 0 since
0/n == 0 for any n != 0. So 2 % 500 == 2. What's the problem?

I don't think that this is right. Modulo returns the remainder of
any number / 10.

For example : 19 % 10 = 9

Check wikipedia for some more math ;)
