Memory Is Numbered Boxes
The one picture every C++ programmer needs: memory is a long row of numbered boxes. We build up arrays, pointers, pointer arithmetic, walking a string with count_x, the null pointer, and copying pointers, using real addresses measured on a Mac.
You will learn
- Picture memory as numbered byte boxes with addresses
- Use arrays, pointers, & and * correctly
- Predict pointer arithmetic for different types
- Handle the null pointer safely
