In 2, define a used to represent a class called the Month, specific requirements are as follows:
(1) private data members:
Int mon: used to represent in value (in February said in January 1, 2, and so on)
(2) public member functions:
In the Month (string Mon) : use English name (the first three letters) to set the value in the
The Month (int n) : with the integer n to set the value in the
Void the show () : output function, according to the data members mon output value (integer) in the English words
The Month next () : returns the next Month
(3) in the main function in the validation of all the members of the class function,
And (the related. H file. CPP file into ex2 folder)
Thank you very much!

The Month Month: : next () {
Int m=mon + 1;
If (m> 12) m=1;
Return the Month (m);
}
Can't directly to mon, otherwise itself is changed,

Also, changing between integer and string, a writing is easy to appear problem, should make a an array to do
String up [12]={" Jan ", "Feb",... }.//short
