The Right-Left Rule
The Algorithm
Examples
Multi-Dimensional Arrays
Three Approaches
I. Fixed-Size ("Static") Arrays
Element Access Formula
II. Semi-Dynamic Arrays: int arr[4]
Don't Forget to Free!
II-b. Alternative: int (arr)[8]
III. Fully-Dynamic Arrays: int arr
Freeing Fully-Dynamic Arrays
Memory Leak Example
Correct Cleanup
argc and argv -- Command Line Arguments
III-b. Flat Fully-Dynamic 2D Array
Pointers to Pointers to ...
Passing Multi-Dimensional Arrays to Functions
Reminder: 1D Arrays Are Passed as Pointers
2D Arrays Follow the Same Rule
sizeof() Behavior
The First Dimension Is Always a Pointer
