Example that gets a month and a year from the user and finds the last day of each remaining month of that year.
int
main()
{
using namespace boost::gregorian;
greg_year year(1400);
greg_month month(1);
// get a month and a year from the user
try {
int y, m;
std::cout << " Enter Year(ex: 2002): ";
std::cin >> y;
year = greg_year(y);
std::cout << " Enter Month(1..12): ";
std::cin >> m;
month = greg_month(m);
}
catch(bad_year by) {
std::cout << "Invalid Year Entered: " << by.what() << '\n'
<< "Using minimum values for month and year." << std::endl;
}
catch(bad_month bm) {
std::cout << "Invalid Month Entered" << bm.what() << '\n'
<< "Using minimum value for month. " << std::endl;
}
date start_of_next_year(year+1, Jan, 1);
date d(year, month, 1);
// add another month to d until we enter the next year.
while (d < start_of_next_year){
std::cout << to_simple_string(d.end_of_month()) << std::endl;
d += months(1);
}
return 0;
