How does the modulus operator work?

Question

Let\'s say that I need to format the output of an array to display a fixed number of elements per line. How do I go about doing that using modulus operation?

Using C

Answer 1

Basically modulus Operator gives you remainder simple Example in maths what's left over/remainder of 11 divided by 3? answer is 2

for same thing C++ has modulus operator ('%')

Basic code for explanation

#include 
using namespace std;


int main()
{
    int num = 11;
    cout << "remainder is " << (num % 3) << endl;

    return 0;
}

Which will display

remainder is 2
