Data types are used everywhere in a programming language like C#. Because it's a strongly typed language, you are required to inform the compiler about which data types you wish to use every time you declare a variable, as you will see in the chapter about variables. In this chapter we will take a look at some of the most used data types and how they work.

bool is one of the simplest data types. It can contain only 2 values - false or true. The bool type is important to understand when using logical operators like the if statement.

int is short for integer, a data type for storing numbers without decimals. When working with numbers, int is the most commonly used data type. Integers have several data types within C#, depending on the size of the number they are supposed to store.

string is used for storing text, that is, a number of chars. In C#, strings are immutable, which means that strings are never changed after they have been created. When using methods which changes a string, the actual string is not changed - a new string is returned instead.

char is used for storing a single character.

float is one of the data types used to store numbers which may or may not contain decimals.
