Arrays & Strings

In this lesson:

• what an array actually is in memory (and why zero-indexing makes sense)
• declaring, initializing, and accessing array elements
• the constant trap: arrays decay to pointers when passed to functions
• C-strings: arrays of char with a hidden null terminator
• the <string.h> functions you'll use most: strlen, strcpy, strcmp
• the buffer-overflow trap and how to avoid it
