easy way to add 1 month to a time_t in C/C++

Question

I have some code that uses the Oracle function add_months to increment a Date by X number of months.

I now need to re-implement the same logic in a C / C++ function.

Answer 1

You can use Boost.GregorianDate for this.

More specifically, determine the month by adding the correct date_duration, and then use end_of_month_day() from the date algorithms
