Description
Artillery
Your task is to create an artillery game. There are two players, a human player and a computer
player. The game plays as follows:
● Ask for the player’s name, this may or may not include spaces.
● Ask for the desired difficulty; easy, medium, or hard.
● An enemy tank is placed at a random distance from the player, you choose a good range
for this value. It must be placed within a reasonable distance to be able to play the
game, meaning it’s always placed to the right of the player tank which is located at x = 0,
and between some limits denoted by a.) and b.) above.
● The enemy tank is placed at a random distance within [a, b] at the beginning of each
game, not each round. The tanks do not move once the game has started.
● There are three rounds
● Each round the player is asked for a velocity and an angle to shoot their artillery at the
enemy. The angle and velocity is shown in yellow above. The input from the player must
be in degrees, but the equation to calculate the projectile’s trajectory is in radians.
You
must convert from degrees to radians then plug into the equation below to find how far
the projectile traveled.
𝑑𝑖𝑠𝑡𝑎𝑛𝑐𝑒𝑇𝑟𝑎𝑣𝑒𝑙𝑒𝑑 = 𝑣𝑒𝑙𝑜𝑐𝑖𝑡𝑦 * 𝑐𝑜𝑠(𝑎𝑛𝑔𝑙𝑒 𝑖𝑛 𝑟𝑎𝑑𝑖𝑎𝑛𝑠)
𝑟𝑎𝑑𝑖𝑎𝑛𝑠 = 𝑑𝑒𝑔𝑟𝑒𝑒𝑠 *

● If the player hits the enemy, the game is over. The player wins!
● If the player misses the enemy, the game will report to the player if they undershot or
overshot and by how much.
● If the player doesn’t destroy the enemy at the end of the three rounds, the enemy wins!
● There are three difficulties: Easy, Medium, Hard
○ A “Hit” is registered if your projectile lands within the ‘width’ of the enemy tank:
■ Easy: enemy tank width = 20 units
■ Medium: enemy tank width = 10 units
■ Hard: enemy tank width = 5 units
For example: If the enemy tank is placed at x = 50, and the game mode is set to easy, then if
the player shot lands in [40, 60] it is registered as a hit. If the tank is placed at x = 75 and the
game mode is medium, a shot landing in [70, 80] will register as a hit.
● At the end of the match, print out a personalized message to the player, including their
name (which may include spaces), that says something about being defeated or
victorious. Feel free to have fun with this, if the player wins on the hardest difficulty you
could be more celebratory than if they win on easy, etc.
Notes:
● You may assume we are getting valid inputs, except for difficulty. If the player enters a
string that represents an invalid difficulty, print a message stating this and terminate the
program gracefully via a return statement.
● Print out the round number and difficulty level at the start of each round
● Print out your shot location each time you fire.
● If you hit the tank, print out the shot location and the tank location.
● Format doubles to two decimal places for output
● It would be a good idea to print a debug statement showing the location of the enemy
tank while testing, then remove the debug statement before submitting your finished
work.

Submission details:
● A .zip folder named lastname_firstname_assignment4.zip
○ Inside this folder should contain the following:
■ Artillery.cpp
■ Makefile (unchanged from what was given to you)
■ a results.txt file that contains at least 5 test runs of your program
■ a reflection.txt file that contains your answers to the following questions:
● What was the most difficult part of this assignment for you?
● What was the easiest?
● If you were to expand this idea and add more features, what would
you add and why?
● Having completed the assignment, if you were to redo it, what
would change in your approach/strategy? How would your
implementation be different from your first attempt? Would it be
easier or harder the second time?
