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.
