8.8. Exercises

1. A resent research study suggests that a person's ideal weight is related to his or her height in inches. They said that a person's ideal weight can be calculated from the following equations:

   Female = 3.5 * height (in inches) - 108
   
   Male = 4.0 * height (in inches) - 128

   Write a program that has the user enter a starting and ending height, calculates a table of ideal weights for males and females, and stores the results in an array. The program should then display the table in either a listbox or listview object.

2. In what way are arrays of objects different from arrays of value types?

3. Write a program that stores 100 random values in an int array and then displays those values in a listbox. Have a Sort button that, when clicked, sorts the values and redisplays them in the listbox.

4. Modify the program you wrote for Exercise 3 so it displays a bar graph for the data, as shown in Figure 8-13.

5. Given the following statements,

   string [] str1 = new string[100];
   string[] temp;
   
   str1[0] = "Hailey";
   // Some more code
   
   temp = str1;

   What does the rvalue of temp equal?
