Understanding control statements

Control statements allow us to control the flow of execution of a program. They also allow us to execute a particular block of code based on a certain condition. C# defines three categories of control statements, as mentioned here:

• Selection statements: if and switch
• Iteration statements: for, while, do-while, and foreach
• Jump statements: break, continue, goto, return, and yield

We will explore each of these statements in detail in the following sections.

The following snippet shows the syntax of an if statement:
