Chapter 6, Problem 54PS

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 $\text{\$}$ and a digit, which shows the size. The size must be between 2 and 9. Table 6-6 shows the four patterns in size 5.

Your program displays a menu and asks the user to choose a pattern and size. But note that it must be robust; it must prompt the user to choose an option only between 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 (user responses are in color):

$\begin{array}{|l|}\hline \text{ M E N U}\hfill \\ \text{1}\text{. Pattern One}\hfill \\ \text{2}\text{. Pattern Two}\hfill \\ \begin{array}{l}\text{3}\text{. Pattern Three}\\ \text{4}\text{.}\text{Pattern Four}\\ \text{5}\text{.}\text{Quit}\\ \begin{array}{l}\text{Choose an Option }\left(\text{between 1 and 5}\right)\text{: 11}\hfill \\ \text{Your Option is incorrect}\text{. Please try again}\text{.}\hfill \\ \text{Choose an Option }\left(\text{between 1 and 5}\right)\text{: 3}\hfill \\ \text{Choose a Pattern Size }\left(\text{between 2 and 9}\right)\text{: 12}\hfill \\ \text{Your Pattern size is incorrect}\text{. Try again}\text{.}\hfill \\ \text{Choose a Pattern Size }\left(\text{between 2 and 9}\right)\text{: 4}\hfill \end{array}\end{array}\hfill \\ \hline\end{array}$

The program must consist of a main function and six other functions called $\text{getOption, getSize, patternOne, patternTwo, patternThree, and patternFour}\text{.}$

Run your program once with the options and sizes shown in Table 6-7. Note that some options and sizes are missing because either the previous option or the size is invalid.
