CSE 1384 - Vectors and Functions Lab 3 Objectives: Continue practicing past concepts Practice using vectors Practice using functions Assignment: Create a program that allows a user to view and alter a class schedule. To make the class schedule, you'll need to use TWO string vectors: courseCodes and courseNames. Note: Throughout the lab, you can assume the user will enter the correct data type you're expecting. So, if you're asking for an integer, assume they will correctly always enter an integer. Your program should utilize four functions:

main Parameters: none Return value: 0 Purpose: Loop through the user menu letting the user choose options until they'd wish to stop ViewSchedule Parameters: codes and class names (both by reference) Return value: none Purpose: display all the items in the vectors. Keep each course code in line with the corresponding course name addClass Parameters: codes and class names (both by reference) Return value: 0 on successful add, 1 on unsuccessful add Purpose: add a course to the vectors. Course codes should be checked for being exactly four characters long -- if it's not, return 1 and end function. If it is, add to the code vector, query for the course name and add to the name vector. Retum O

removeClass Parameters: codes and class names (both by reference) Return value: 0 on successful remove, 1 on unsuccessful remove Purpose: remove a course from the vectors. Should not display the vectors here. Ask the user which item they'd like to remove ... check to see if the number is valid (0

Exit Exit the menu View Schedule Check to see if the vector contents aren't empty Call view schedule function if they aren't Add Class Call add class function Check to see if 0 or 1 - tell the user whether a successful addition occurred or Remove Class Check to see if the vector contents aren't empty If they aren't Display vector contents Call remove class function Check to see if 0 or 1 - tell the user whether a successful removal occurred or not Incorrect menu option Display an error to the user that the menu option isn't valid Hints: For the course name, you will need to get the entire contents of the line. So, if they entered in Intermediate Programming" or "Introduction to Computer Programming", make sure you get the entire line. The string function "getline" is very useful for this, as the vectors are string type. You'll find, if you try to mix the input types

: cin>> variable getline(cin, variable) That a getine following a "cin >> variable" line will be skipped. There are two solutions to this:

Make all your variables strings (even menu option queries) and make every input a getline statement Put the line "cin.ignore(" before you run your getiline command if you've mixed "cin >> variable statements in your code Example Execution (without BONUS): lcome to the class schedule manager. - Exit Vie Schedule Add Class Remove Class ich es option would you likel 6 That's not a valid u option.
