What is a String in C? (Character Arrays & The Null Character) || C Programming || Lesson 124 ||

Description:
In this class we will understand What is a String in C? (Character Arrays & The Null Character).

There is no "string" data type in C! So how do we work with text? In this foundational tutorial, we explain the concept of Strings as Character Arrays.

Learn the critical role of the Null Character (`\0`) in terminating a string, and visualize exactly how text is stored in memory. We'll also cover the key difference between single quotes ('A') and double quotes ("A").
