Function Exercise#1

1. First copy the program DrawCirc.C from my public directory.
2. Make a function called draw_circle() so that main looks like so:

       int main()
       {
         draw_circle();
         draw_circle();
         draw_circle();
         return 0;
       }
   

3. Now change your main() so that it prompts the user once to allow them to enter their own character for the circles. NO global variables!

Function Exercise#2

1. Copy circle.C out of my public directory
2. Your mission, since I'm forcing you to accept it, is to integrate the circle.C program with the square function that we just went over.
3. In the circle.C program we find the area by using pi * radius * radius.
   Replace radius * radius with the square function.
4. Something you must decide : which version of square are you going to use? The one from square1.C, square2.C, or square3.C? Is there only one that will work? Will all of them work?
   NO globals!

Switch/Function Exercise#3

• Time to make your first HUGE program!
• First make a new program called my_proj.C
• This program will run the exercise you just did and Project#1 and Project#2. (if you deleted them use projects #3 and #4)
• Cut and Paste each project and the above exercise to your my_proj.C
• Turn each project and the exercise into functions.
• In main() ask the user which project or exercise he/she wants to see:

       My list of projects and exercises:
          1 : Project 1
          2 : Project 2
          d : Draw Circle exercise
  
       Which project or exercise do you want to run? (1-2, or d)
  

• Then create a switch statement to take the input and run the appropriate function.
