I got this paragraph from a Programming Language book:
Understanding selection statements:
Every application needs to be able to select from choices and branch along different code paths. The two selection statements in C# are if and switch. You can use if for all your code, but switch can simplify your code in some common scenarios such as when there is a single variable that can have multiple values that each require different processing.
Would anybody explain it to me that what does exactly the bold section say?
