Working with variables, operators, and expressions in Microsoft Visual C#
This chapter from Microsoft Visual C# Step by Step, 8th Edition introduces you to the elements of Microsoft Visual C# syntax and semantics, including statements, keywords, and identifiers.
After completing this chapter, you will be able to:
-
- Understand statements, identifiers, and keywords.
- Use variables to store information.
- Work with primitive data types.
- Use arithmetic operators such as the plus sign (+) and the minus sign (–).
- Increment and decrement variables.
Chapter 1, “Welcome to C#,” presents how to use the Microsoft Visual Studio 2015 programming environment to build and run a console program and a graphical application. This chapter introduces you to the elements of Microsoft Visual C# syntax and semantics, including statements, keywords, and identifiers. You’ll study the primitive types that are built in to the C# language and the characteristics of the values that each type holds. You’ll also see how to declare and use local variables (variables that exist only in a method or other small section of code), learn about the arithmetic operators that C# provides, find out how to use operators to manipulate values, and learn how to control expressions containing two or more operators.
