Section 19.13 Summary

In this chapter we studied pointers (addresses of variables) and how they can help with writing better code. We covered:

The address of a variable
Dereferencing a pointer
Arrays and pointers
Passing arrays to functions
Arrays don’t know their own sizes
Using pointer arithmetic to access array elements

Pointers make it possible to break up a large problem into many small sub-problems. Summary of designing and testing methods discussed in this chapter:

Top-Down Design is used to break down larger problems into manageable pieces.
Bottom-Up Testing is used to test the individual pieces.
Top-Down Testing is used to check the flow of your program.
