Digression: get the current local date and time in C++

1. time.C. The function localtime fills up a structure with information, and returns a pointer to this structure.
   (tm_sec might be a leap second.)

Create a C++ class

Pass some information down to three functions (print, next, and next) that do all the work.

2. 3ints.C. Hold the information about a date in three ints.
3. struct.C. Hold the information about a date in one struct.
4. Hold the information about a date in one object.
   1. obj1.C. An object with data members and (non-static) member functions
   2. obj2.C. Add a constructor and a static data member.
      Make the data member private.
      Exercise.
      Now that we have a constructor that throws exceptions, what would happen if the main function tried to create a

      	date d {2, 30, 2025};   //Bad date: there is no Ferbruary 30
      

      Can you catch the exception?
   3. Separate header and implementation files.
      #include with "double quotes" looks in your current directory for the header file.
      #include with <double quotes> looks in the directory /usr/include/c++/14 for the header file (on our machine storm.cis.fordham.edu).
      Compile this three-file program (consisting of date.h, date.C, main.C) with

      c++ main.C date.C
      

      1. date.h. The header file for class date.
      2. date.C. The implementation file for class date.
      3. main.C. A C++ program that uses objects of class date.
      4. main2.C. Another C++ program that uses objects of class date.
         
         Compile this three-file program (consisting of date.h, date.C, main2.C) with

         c++ main2.C date.C
         

Class stack

5. last semester’s stack example
6. An object that holds a stack of ints:
   1. stack.h
   2. stack.C
   3. main.C
7. Don’t build your own: the C++ Standard Library already has a class stack.
