Overview

In this chapter, you will learn how to:

• Declare (create) variables

• Use the built-in C++ data types

• Create user-defined types

• Add member variables to a class

• Use the Microsoft .NET Framework String class

• Assign values to a variable

• Create expressions using the C++ operators

• Cast (change) the type of a variable

In the previous chapter, we looked at the advantages of object-oriented programming and developed a simple program to illustrate the creation and use of classes.

In this chapter, we’ll take a closer look at how to create and use variables, the fundamental data types of C++, how to access and use classes from the .NET Framework, and how to create expressions using the C++ operators.
