Chapter 9, Problem 5PP
Program Plan Intro
Computer Lab Logging
Program Plan:
- Include the necessary libraries.
- Use namespace.
- Define the constants and type definition.
- Define the function prototypes.
- Define the function “createArrays()” to create the dynamic array for the lab.
- Declare the variables.
- Define the first array which is the array of labs.
- Define the second array which defines the size of the lab.
- Define the function “freeArrays()” to release the allocated memory.
- Define the function “showLabs()” to display the status of all labs.
- Define the function “login()” to simulate the user login.
- Declare the required variables.
- Get input from the keyboard, validating data ranges.
- Use a while loop to repeat operation until user requires.

- Declare the required variables.
- Get input from keyboard, validating data ranges.
- Use a while loop to repeat operation until user requires.
- Store the value and display the message.
- Use a for loop to repeat operation until the user is found out.
- Otherwise display that user is not logged in.
- Define the main method.
- Declare the variables that are required for program.
- Initialize lab sizes to those given in the problem.

To begin you will create a College python class that keeps track of the csollege's unique id number, name, address, phone number, maximum students, and average tuition cost. Once you have built the College class, you will write a program that stores College objects in a dictionary while using the College's unique id number as the key. The program should display a menu in this order that lets the user: 1) Add a new College 2) Look up a College 4) Delete an existing College 5) Change an existing College's name, address, phone number, maximum guests, and average tuition cost. 6) Exit the programarrow_forwardShow all the workarrow_forward
