Creating Seating Charts I NEED THE PROGRAM WRITTEN IN C! Introduction to computing and Engineering!

Description of Programming Tasks

Task 1 - Empty Classroom Seating Chart

Write a program that prints a seating chart (similar to that from the Project 1a Description) for an empty classroom of size specified by the user. Have the user enter in both the number of rows and the number of seats per row. Make sure the user input is reasonable, by checking that the number of rows is 26 or less, that the number of seats per row not greater than 30, and that both are at least 1. Then, print to screen a carefully formatted seating chart where each row is represented with a letter, and every seat in each row is uniquely identified with a letter and a number (see the sample output section below for examples).

Some important considerations:

• The format of your seating chart must match the sample output precisely (including whitespaces) in order to pass the test cases
  • Capital letters.
  • Two digits for all numbers (e.g. A05, K14, W24, etc.).
  • Single space after each seat (including the last seat per row, before the new line character " "), which means each seat uses a total of 4 characters.
• The first row is at the bottom of the seating chart, and thus must be printed last.
• To achieve this task for general input from the user, a nested loop must be used. However, arrays and/or structs must not be used as they are beyond the scope of the course to this point.

Task 2 - Every-Other Seating Chart

Extend your program to also print out a seating chart where every other seat is taken by a student. Represent a taken seat as an "X". To keep the formatting neat, make sure to still reserve 4 total characters for each seat, i.e. if seat B12 is taken, replace it with an "X" that has one space before the "X" and two spaces after (again, see the sample output section below for examples). Additionally, report the number of students that can be seated using this arrangement.

One important consideration: The first seat, A01, is taken, in addition to every other seat in row A. Then, the taken seats in row B are offset from row A, and the pattern repeats for all the rows.

Task 3 - More-Complicated Seating Chart

Extend your program to also print out a seating chart that matches the pattern from the Project 1a filled seating chart. Use the logic you developed for your Project 1a program, wrap it into appropriate loop(s), and modify the functionality for general user input for number of rows and seats per row (again, see the sample output section below for examples). Additionally, report the number of students that can be seated using this arrangement.

Sample Input/Output

The following are sample executions of the program with mixed input and output. Recall: the program should only take in two integer inputs for the number of rows and number of seats per row.
