Types 🔤

A type in C is a representation of a certain “type” of data. Every value in C has a “type.” Here are the list of the 3 common types we will be dealing with:

Name	Description	Examples
Integer	Represents an integer.	0, -10, 2, 150, -349
Float	Represents a decimal number, with at most 7-8 decimal places.	0, -10.43, 2.23420, 150.493, -349, -4230.340
Character	Represents a single symbol.	‘a’, ‘D’, ‘1’, ‘#’, ‘^’, ‘%’, ‘&’
String	Represents a sequence of characters.	“hello world!”, “the quick brown fox”

More on Strings

As you learned in Lesson 1, a sequence of characters is called a string. Although many programming languages have a dedicated string type, C does not.

Note

The name “string” comes from using the word “string” to describe lists of objects, such “a string of beads”. For the string type, it means “a string of characters”.
