Calendar Program Remove Modulus Help

[Redrover36]

How can I make this work without the modulus operator? Its for a calendar program...

  void printDays(int firstday, int day)
{
    for (int j = (1+firstday); j <= (day+firstday); j++)
    {
        cout << (j-firstday) <<"\t";
        
        if( j%7 == 0)
        {
            cout << endl;
        }

You can use integer division combined with a subtraction, or repeated subtraction in your very own module function.

You could also use a well designed if, eg if not between 0 and 7 inclusive then ..., in your design or even a while loop.
