  • Dr. Abraham Up until now you have been declaring variables of simple (atomic) data types. Suppose you want to keep inventory of things you sell. Each item you have in stock has a name (string), a price (double), and a quantity (integer). It would be nice to keep them together and give it one name. That is what “Struct” does for us. In other languages it may be called a “Record”. We can use a class as well which is covered in the next chapter. With object oriented programming it does not make sense to use struct any more. Nevertheless...

  • I have noticed over the years that students have great deal of difficulty dealing with composite and abstract data types. Therefore we are going spend an extra lab review material we have already learned. Vector data type, a variation of array, will be introduced as well. Vector data type (Vector Class) can be used when you need an array that grows dynamically. However, C++ does not allow us to declare size of an array dynamically like some other languages. It is important for you to declare the maximum size you will need. Suppose you are writing a program to keep...

  • Members that contain executable code are collectively known as the function members of the class. The function members of a class are the methods, properties, indexers, operators, constructors, and destructors of the class. A class-declaration creates a new declaration space (§3.1), and the class-member-declarations immediately contained by the class-declaration introduce new members into this declaration space. The following rules apply to class-member-declarations: • • • Constructors and destructors must have the same name as the immediately enclosing class.
