Data Types

C# data types define the type of data a variable can store, such as integers, floating-point numbers, characters, or Boolean values. The data types are essential to declare specific variables to store the related value, memory optimization, performance improvements, and code readability.

In this chapter, you will learn:

• Different C# data types.
• Declaring and assigning the variable with the use of specific data types.
• Best practices about C# data types to write efficient code.
• Common mistakes to avoid while declaring and using the data types.

The variables in C#, are categorized into the following types −

• Value types
• Reference types
• Pointer types
