Need help trying to loop the complex seating chart

Task 1 - Empty Classroom Write a program that prints a seating chart (similar to that from the Project04 Description) for an empty classroom of size specified by the user. Have the user enter in both the number of rows in the classroom and the number of seats per row in the classroom. 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 is not greater than 25, and that both are greater than 0. 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 user-input prompts and Seating Chart titles must match the sample output precisely to pass the test cases. The format of your seating chart must match the sample output precisely in order to pass the test cases... o Capital letters. o Two digits for all numbers (eg. A05, K14, W24, etc.). o 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 Arrangement 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 not taken, but A02 is taken with every other seat in row A also taken. 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 Projecto4 filled seating chart. Use the logic you developed for your Project04 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.
