Requirements

• Write a C program that can create four different patterns of different sizes. The size of each pattern is determined by the number of columns or rows. For example, a pattern of size 5 has 5 columns and 5 rows. Each pattern is made of character $ and a digit, which shows the size. The size must be between 2 and 9. The following shows the four patterns in size 5.

  Pattern 1              Pattern 2              Pattern 3             Pattern 4 
  5$$$$                  $$$$5                   $$$$$                 $$$$$ 
  $5$$$                  $$$5$                  $$$$5                 5$$$$ 
  $$5$$                  $$5$$                  $$$55                 55$$$ 
  $$$5$                  $5$$$                  $$555                 555$$ 
  $$$$5                  5$$$$                  $5555                 5555$ 
             

  Your program displays a menu and asks the user to choose a pattern and size. note that it must be robust; it must prompt the user to choose an option only ieen 1 and 5, and a pattern size only between 2 and 9. You are to print the menu and the user's response. The following example shows all user menu responses, including potential errors:

  
                           M E N U
  
                       1.  Pattern One
                       2.  Pattern Two
                       3.  Patten Three
                       4.  Pattern Four
                       5.  Quit
  	
  Choose an Option (between 1 and 5): 11 
  Your option is incorrect. Please try again.
  Choose an Option (between 1 and 5): 3 
  Choose a Pattern Size (between 2 and 9): 12 
  Your Pattern size is incorrect. Try again. 
  Choose a Pattern Size (between 2 and 9): 4 
        

  The program must consist of one main function and six other functions called GetOption, GetSize, PatternOne, PatternTwo, PatternThree, and PatternFour.
