Chapter 11 Exercise Set 1

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.
