In one European country there are two types of music festivals
national and international.
All take place in one or more (sometimes random) days, but
all days are in the same calendar year.
For the national festival is significant whether or not have jury (that is giving additional prizes). For international is important if they are giving the the top prize
(Grand prix).
Create a class MusicFestival which will have function main () in which will be constructed arrays of objects from these classes (National and International).
Implement user agent through the menu with the following options:
1.Addition of Festival (National and International)
2.Changing of the data provided by code from Festival
(Change the number of participants, and in international festivals plus-change
awarding the main prize)
3.Showing festivals from a given class (National or International)
4.Computation of the number of awards granted to all festivals that are
held in a given year (which is entered from the keyboard). For each type of festival
it is known that by standard are given 3 awards from the audience.
For national matches depending on whether a jury awarded another 3 awards, and
in international competitions depending on whether it last more than a day
held for each day shall be granted one award plus eventually granted and the main
prize (if the Festival is giving award Grand Prix).
Otherwise, if the festival lasts only one day, then it is given the main prize only if
