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.
  • Store the value and display the message.
  • Finally, assign that station to the user.
• Define the function logoff() to logoff that user.
  • 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 user requires.
  • Display the message of the user logged in.
  • Otherwise display that user is not logged in.
• Define the function “search()” to search that user.
  • 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.
  • Create a ragged array structure.
  • Use a while loop to repeat operation until user requires.
  • Perform login, logoff or search function.
  • Free memory before exiting.
