Question

I need help in order to get the below part right

Required! You MUST have a single function named "printMonth" that prints out ANY month, based on its parameters.  In other words, don't create 12 separate functions, one named "printJanuary", one named "printFebruary," and so on.  In addition, you must have only ONE call to this printMonth function, in a loop that calls the function 12 times.

Can somehelp me with setting it up with a switch statement or something that fits the above criteria?

#include <iostream>

    cin >> firstDay;

    cout << endl << setw(17) << currentYear << endl << endl;

    totalDays = 31;
    printMonth (firstDay, totalDays);

        totalDays = 29;
