Chapter 4: Smooth Operators
In This Chapter
Performing a little arithmetic
Doing some logical arithmetic
Complicating matters with compound logical operators
Mathematicians create variables and manipulate them in various ways, adding them, multiplying them, and — here’s a toughie — even integrating them. Chapter 2 of this minibook describes how to declare and define variables. However, it says little about how to use variables to get anything done after you declare them. This chapter looks at the operations you can perform on variables to do some work. Operations require operators, such as +, –, =, <, and &. I cover arithmetic, logical, and other types of operators in this chapter.
Writing programs that get things done is good. You’ll never make it as a C# programmer if your programs don’t do something — unless, of course, you’re a consultant.
Performing Arithmetic
The set of arithmetic operators breaks down into several groups: the simple arithmetic operators, the assignment operators, and a set of special operators unique to programming. After you digest these, you also need to ...
