I am just beginning in a C++ class and I am having a hard time setting up the code for using a modulus operator. The problem assigned has user input as name and hours worked. The program is to output the name, weeks worked, days worked, and hours worked based on the hours worked input. I understand how to break it down in calculation; but our instructor wants us to a modulus operator. I am unsure of how to do this. Any hints?

thanks!

Here's what i have so far:
CODE

int main()
{
//declare constants and variables
string name = "";
const int HOURSWEEK = 40;
const int HOURSDAY = 8;
int hours = 0;
int hrsWorked = 0;
int daysWorked  = 0;
int weeksWorked = 0;

//get user's input
cout << "Enter employee's name: ";
cin >> name;
cout << "Enter employee's hours worked: ";
cin >> hours;

//calculate weeks, days and hours worked

weeksWorked = hours / HOURSWEEK

***
This is where I'm not sure how to set up the mod to get to daysWorked.

Maybe your instructor want's your output in this manner.
x Weeks Worked + 3 Days.
(that is, if the number of hours doesn't exactly correspond to an exact value of weeks_worked).

In that case you can use something like this:
CODE

days_worked = weeks_worked % 7;

This will give you the value (remainder) of the number of days left which doesn't complete a week's worth of work.

Modulus( A, B ) or A % B = A - floor( A / B ) * B


floor( ...) means always round down to the nearest integer.
