Article Summary
C strings are null-terminated character arrays — the foundational way C stores and manipulates text. This article covers how to create, access, copy, concatenate, and compare C strings using key functions like strlen(), strcat(), and strcmp(). You'll gain a solid working understanding of how C strings behave in memory.
In C, a string is defined as an array of characters. A string array will always terminate with a special character, “ .” Strings are frequently used and manipulated in C as a way of storing and printing text. For example, a string might be a user name, a password, or an email address. This character array can be interacted with character by character.
Learning how to manipulate strings is one of the foundational skills of working with C. Strings can be collected from the user, printed to the console, and printed to files. They can be re-written in different orders (such as reversed), concatenated (added to), or cut (removed from). You can collect a string, store a string, or return a string.
