Question

Please use c# and write a console application

Part 1) A small airline has just purchased a computer for its newly automated reservations system. You have been asked to develop a new system. You are to write an application to assign seats on each flight of the airline’s only plane. The plane has ten rows and each row has 2 seats (total capacity: 20 seats). The first five rows are for first class passengers, while the remaining rows are for economy passengers. The application is used by an airline employee who is given the task of assigning all seats to passengers (one passenger at a time). Your application should display the following alternatives: Please type 1 for First Class and Please type 2 for Economy or type 3 to see the status of all seats. If the user types 1, your application should assign a seat in the first-class section (rows 1–5). If the user types 2, your application should assign a seat in the economy section (rows 6–10).
If the user types 3, the application will display the status of all seats (“A” for available and “X” for booked) as shown below. The application will continue to ask for the user’s input until the flight is full or the user suggests that they do not want to assign anymore seats.
Availability Status:
X   X
X   X
X   A
A   A
A   A

X   X
X   X
X   X
X   X
A   A

Your application should never assign a seat that has already been assigned. When the economy section is full, your application should ask the person if it is acceptable to be placed in the first-class section (and vice versa). If yes, make the appropriate seat assignment. If no, display the message "Next flight leaves in 3 hours." You will need to use a multi-dimensional array to solve this problem. 

Part 2) Use a one-dimensional array to solve the following problem: A company pays its salespeople on a commission basis. The salespeople receive $200 per week plus 9% of their gross sales for that week. For example, a salesperson who grosses $5000 in sales in a week receives $200 plus 9% of $5000, or a total of $650. Write an application (using an array of counters) that determines how many of the salespeople earned salaries in each of the following ranges (assume that each salesperson’s salary is truncated to an integer amount):
a) $200–299
b) $300–399
c) $400–499
d) $500–599
e) $600–699
f) $700–799
g) $800–899
h) $900–999
i) $1000 and over
The application will accept sales amount until the user enters -1 to end (as shown in figure 2.1 below). At this point, the application calculates the salary and updates the appropriate counter of the array. For instance, if the salesperson gets a total salary of $565, you will update the counter that is counting totals between the $500-$599 range.

Figure 2.1. Receiving input from user

Note that you do NOT need to store the individual salary of the salesperson. Summarize the results in tabular format Use only a for loop to display the output.

Final output showing all ranges and the number of agents that received commission in that range
