Strings

This lesson is part of Intro to Programming · All levels

Summary

This lesson discusses strings as a type of data that stores text, usually a set of characters in a quotation mark. Strings support operations such as combining (concatenation), taking parts, finding positions, and changing uppercase/lowercase. Because strings are immutable in many languages, any operation always produces a new string.

Key points

String stores text and writes it with quotation marks
Concatenation combines two or more strings
Inbuilt functions of calculating length, searching, and changing letters
Strings are immutable in many languages so the operation produces a new string
