Chapter 8 Exercise Set 0: Chapter Review

1. Write function named lower_right that takes a Rectangle as an argument and returns a Point with the location of the lower right hand corner.

2. Write a function named find_area that takes a Rectangle as an argument and returns the area of the rectangle.

3. Use the sizeof operator you first met back in the Values section in chapter 2 to determine the size of a Rectangle.

4. Compile and run the following program:

   #include <iostream>
   using namespace std;
   
   struct A
   {
       char a;
       char b;
   };
   
   struct B
   {
       char a;
       double b;
   };
   
   struct C
   {
       A a;
       B b;
   };
   
   int main() {
       A a = {'a', 'A'};
       B b = {'B', 3.14};
       C c = {{'c', 'C'}, {'d', 4.9}};
       cout << "sizeof(a) is: " << sizeof(a) << endl;
       cout << "sizeof(b) is: " << sizeof(b) << endl;
       cout << "sizeof(c) is: " << sizeof(c) << endl;
       return 0;
   }
   

   Can you explain the results? Do some web research to see if you can understand what you see. Try additional experiments to test your understanding.

5. Write a function with a const parameter, and then modify it in the function body. Try compiling it and note what happens on your system.

6. Rewrite the increment function from the Modifiers section without iteration using the approach introduced in the Incremental development versus planning section.
