If this is your first exposure to pointers, you may want to reflect on what you have learned before reading the next chapter. This chapter has explained the basic uses of pointers, and you can write a great many useful programs using only these techniques. If you're not comfortable with all these ideas, you may want to experiment with them before reading more about pointers.
The next chapter, “Advanced Pointers,” examines further uses of pointers, including multiple indirection and pointers to structures.
