Chapter 7, Problem 48RQE
Write a remove member function that accepts an argument for a number of units and removes that number of units of an item from inventory. If the operation is completed successfully it should return the number of units remaining in stock for that item. However, if the number of units passed to the function is less than the number of units in stock, it should not make the removal and should return - 1 as an error signal.

Moving Between Rooms - Navigation
In this assignment, you will be working with a given "rooms" dictionary and associated constants to create a simple text-based game. Your main task is to develop a function that allows the player to navigate through the rooms based on the given specifications.
You need to implement the function found in the starter code to the right
The function should take into account the following conditions:
If the direction leads to an exit, set the next room to the exit and the message to "Goodbye".
If the direction is invalid, set the next room to the current room and the message to "No such direction".
If the direction is valid, but you cannot go that way, set the next room to the current room and the message to "You bumped into a wall".
If the direction is valid and you can go that way, set the next room to the room in that direction and the message to "Empty".
To help you understand how the function will be integrated into the gameplay loop, the following…

Write a function that allows you to modify a Planet in the SolarSystem class. You can choose to pass a Planet into this function, or have the function prompt for planet information. Either way, you need to be able to specify the Planet at a specific index to be modified.
This is an example of how it could potentially look in the main:
// code that declared a SolarSystem the_system// and assigned planetsPlanet p("X", 2000, 4000);int index = 2;the_system.changePlanet(p, index);

- When the following program is executed, it terminates with an error. Which option best describes the cause of this error? Question options: The function will terminate the program due to the recursive limit being reached. The function will terminate the program due to a type mismatch when evaluating an operator. The function will terminate the program due to invalid syntax. The function will terminate the program due to an invalid type conversion. The function will terminate the program due to it accessing an invalid list index. None of these optionsarrow_forwardc++ Write a class named TestScores. The class constructor should accept an array of test scores as itsargument. The class should have a member function that returns the average of the test scores.

It has member functions that calculate the perimeter and the area of the rectangle. It has setter and getter functions for both length and width. The program should ASK THE USER TO INPUT length and width value. The set functions should verify that length and width are each floating-point numbers larger than 0.0 and less than 20.0. A sample output of your program should look like follows: length = 1.0; width = 1.0; perimeter = 4.0; area = 1.0 another example: length = 5.0; width = 4.0; perimeter = 18.0; area = 20.0 There should be three files and ONE class only. .h file contains class definition, .cpp file contains the implementation of the class in .h file and main.cpp should contain the driver code.arrow_forward
