Chapter 9 Exercise Set 0: Chapter Review and Exploration

1. Make a file named swaps.cpp that includes all three versions of swap functions presented in the chapter with calling code in main. Compile and then run your program several times, observing what happens.

2. Write a function named shuffle, that takes an array as an argument and randomly “shuffles” the elements in the array. You can create two versions of this function, one that is a modifier and one that is a pure function.

3. Write a function named str_len that takes a C string as an argument and returns the number of characters in the string.

4. Read Heap vs. Stack Memory and prepare a summary presentation of the key difference between stack memory and heap memory and the times and reasons for using each.

5. Write a program named talkin_trash.cpp that illustrates the two concepts of arrays being memory unsafe and garbage in, garbage out discussed in the chapter. Be creative. The best solution to this exercise will be a program example that helps others reading your code understand these two concepts.
