CPS $200$: C$++$ Programming

Final Computer Project

It's your first day of work at Minnesota Ore Mining, Incorporated $($MOM$,$ Inc.$)$ and you have been assigned to a project to develop a semi$-$automatic ore$-$loading vehicle. Your part of the project is to design a high level program that will test the capabilities of the vehicle by simulating its operation in a single level underground cavern. It involves evaluating the ability of the vehicle to travel through a $22$ cavern and report on the amount of ore present in a visited chamber and whether or not to load the ore into the vehicle.

The testing of the vehicle's operations consists of:

reading a valid command from the keyboard

determining if the choice of direction is allowable by comparing it to the known exit from the chamber

displaying the chamber's allowable exit and an appropriate error message if the choice of direction is not allowable

asking if ore should be loaded into the vehicle

keeping a running total of how much ore was loaded from each chamber and how much is left in each chamber if loaded

The valid commands include:

$N,n$ travel north one chamber

E$,$e travel east one chamber

S$,$s travel south one chamber

$W,w$ travel west one chamber

The allowable exit from each chamber is:

East from chamber $(0,0)$

West from chamber $(1,1)$

The amount of ore in each chamber:

Chamber $(0,0)=2\mathrm{.}3$ tons

Chamber $(1,1)=1\mathrm{.}7$ tons

North from chamber $(1,0)$

South from chamber $(0,1)$

Chamber $(1,0)=4\mathrm{.}8$ tons

Chamber $(0,1)=3\mathrm{.}4$ tons

Other conditions:

Once the vehicle has gone through an allowable exit, the chamber door behind it is closed. Hence, there is only one allowable exit from each chamber.

Variables must be used to store the initial ore weight in each chamber and the other to store the allowable exit from each chamber.

The program terminates once the vehicle is back at chamber $(0,0).$

The program should ask the user if ore should be loaded onto the vehicle from that chamber. If the user enters $"y",$ the program should inform the user how much ore is in the chamber and how much of it should be loaded onto the vehicle.

Do not accept a negative number for the ore loaded and do not accept an amount of ore that is more than what is in that chamber.

The final report should display how much total ore was loaded into the vehicle.

The program's if statements should compare the user's responses to the value stored in the arrays.

The program should display a final report of the amount of ore left in each chamber after visited.

Sample Output

The vehicle is in chamber $(0,0).$

The ore in this chamber is $2\mathrm{.}3$ tons.

Load the ore? $(\frac{y}{n})$:$y$

The ore in this chamber is $2\mathrm{.}3$ tons.

Enter the amount to load: $2\mathrm{.}3$ tons.

Input one of these choices $(\frac{N}{S}\frac{?}{?}\frac{E}{W})$:$E$

That is the valid exit!

You are now in chamber $(1,0).$

The ore in this chamber is $4\mathrm{.}8$ tons.

Load the ore? $(\frac{y}{n})$:$y$

Enter the amount to load: $3\mathrm{.}5$ tons.

Input one of these choices $(\frac{N}{S}\frac{?}{?}\frac{E}{W})$:$N$

That is the valid exit!

You are now in chamber $(1,1).$

The ore in this chamber is $1\mathrm{.}7$ tons.

Load the ore? $(\frac{y}{n})$:$n$

Input one of these choices $($N$/$S$/$E$/$W$)$:W

That is the valid exit!

You are now in chamber $(0,1).$

The ore in this chamber is $3\mathrm{.}4$ tons.

Load the ore? $(\frac{y}{n})$:$y$

Enter the amount to load: $5\mathrm{.}3$ tons.

That amount is more than the ore in this chamber!

Enter the amount to load: $1\mathrm{.}4$ tons.

Input one of these choices $(\frac{N}{S}\frac{?}{?}\frac{E}{W})$:$N$

Not a valid exit for chamber $(0,1).$ The valid exit is: $S.$

Input one of these choices $(\frac{N}{S}\frac{?}{?}\frac{E}{W})$:$S$

That is the valid exit!

You are now in chamber $(0,0).$

The amount of ore in the vehicle is: $7\mathrm{.}2$ tons.
