Homework Rules

Marked in red is what you need to figure out. Even with the omissions, someone will probably cyber-whip me for helping you this much.

Code:

---

#include <iostream>


int main ()
{
short x;

std::cout<<"enter a number";
std::cin>>x;

    short a=(x&#37;10);
    short b=(?%?)?10; 
    short c=(x/?);

std::cout<<?<<?<<?<<std::endl;
 
    std::cin.ignore();
        std::cin.get();

   
    return 0;
}

Yup, that's about as far as you can go without giving the whole game away :)
