Programming Assignment 3

Assignment Date: Tuesday, March 12
Due Date: Thursday, April 4
DDD: Thursday, April 11

Instructions

• C++ operators +=, -=, *=, /=, %=, ++, --, <<, >>, &, |, ^, and ~ in addition to those covered earlier in the course. .
• Creating and using functions including void and value returning functions and functions whose parameters include incoming, outgoing, and incoming/outgoing types.
• One-dimensional and two-dimensional arrays.

1. Create a new project in Visual Studio. You may call the program anything you wish. Many students like to keep it simple and just call the project something like Program_3 or ProgAssignment_3.
   
   
2. Add a .CPP source code file to the project. You can name the source file something like Prog3Main.cpp. Place your main() function in this file.
   
   
3. When you have completed writing the code, compile the program. If the program does not compile look carefully at the errors listed by the compiler and fix those errors. Also pay attention to the warnings the compiler gives you.
   
   
4. When your program compiles, run it and test it thoroughly to make sure it is working correctly. Do not turn in your program till it is fully tested and you know the output is correct based on the inputs. Just because you get an output does NOT mean the program is working correctly. The instructor will compare your program's output to the known correct output. If it does not match you will get no credit.
   
   
5. When you are sure the program is working correctly e-mail your program file (the .cpp file) to the instructor. Make sure you are sending the .cpp file and not another file. See the Submit Projects link on the web page for details.

1. The International Civil Aviation Organization Alphabet is a series of words which are used to represent each letter of the alphabet. These are used in critical radio communications between airplanes and ground, and between airplanes in flight to avoid misunderstanding. The code words are given in the list below:
   

   Letter	Word	Letter	Word
   A	Alpha	N	November
   B	Bravo	O	Oscar
   C	Charlie	P	Papa
   D	Delta	Q	Quebec
   E	Echo	R	Romeo
   F	Foxtrot	S	Sierra
   G	Golf	T	Tango
   H	Hotel	U	Uniform
   I	India	V	Victor
   J	Juliet	W	Whiskey
   K	Kilo	X	X-ray
   L	Lima	Y	Yankee
   M	Mike	Z	Zulu

   
   Write a C++ program that inputs a string and output a series of ICAO words that would be used to spell it out. For example:
   
   Enter string: Program Test.
   Phonetic version is: Papa Romeo Oscar Golf Romeo Alpha Mike Tango Echo Sierra Tango
   
   Note that there is a space in the string being translated and letters can be entered either upper or lower case. Any characters other than alphabet or the space should be ignored.
   
   You should create a function called BuildCodeArray to build an array of strings of the ICAO words.
   
   You should create a second function called TranslateString that takes a string and translates it into the ICAO spelling.
   
   After printing the ICAO words the application should ask the user if they want to translate another string and continue looping until the user indicates they do not want to translate another string.
   
   Be sure to use proper formatting and appropriate comments in your code. Provide appropriate prompts to the user. The output should be clearly labeled and neatly formatted.

2. Write a number-guessing game in which the computer selects a random number in the range 1 to 100, and users get a maximum of 20 attempts to guess it.
   
   After each guess there should be some hint given to the player as to how close that guess was. If the guess was only 1 away print a hint like "That guess was hot". If the guess was within 5 points (high or low) print a hint like "You're getting warm". If the guess was within 10 points print a hint like "Your guess is still cool". If the guess was more than 10 points away print a hint like "You're guess is cold".
   
   At the end of each game, users should be told whether they won or lost, and how many guesses it took if they got it correct. To make the game more interesting, the program should vary the wording of the messages that it outputs for winning, for losing, and for asking for another game. Create as many as 5 different messages for each of these cases and use random numbers to choose among them. You should put this functionality in two functions called SayYouWon and SayYouLost
   
   At the end of each game the player should then be asked if they want to play again. The user should be allowed to play as many games as desired. When the user quits, the program should output the total number of wins and losses.
   
   You should ceate a third function called CheckGuess that takes the player's current guess and the number selected by the computer and prints an appropriate response as described above. It might be useful to have the function return a boolean value; true if the player guessed the number and false if not.
   
   You should create a fourth function called GetRandomNumber that generates and returns a random number when passed the range in which to select the random number.
   
   To generate a random number you must include one header file:
   

       	#include <stdlib.h>
   	

   You will also need the time header file if you want to use time to seed the random number generator.

       	#include <time.h>
   	

   Somewhere at the beginning of the program you will need to make one and only one call to the srand function to seed the random number generator. It requires an unsigned int value to be passed to it. The easiest way to insure that this is a relatively random seed number is to pass in the current time in seconds.

       	srand((unsigned int)(time(NULL)));
   	

   To generate a random number between a 1 and 100 use the following. Assume that value is an int. The rand() function generates values between zero and RANDMAX.

         value = rand() % 100 + 1;   // Generate random numbers from 1 to 100
                                      // FYI:  A more generic function will find a random number in
                                      //    a range from low to high with: rand() % (high - low + 1) + low;   
   	

   This application should provide a good opportunity for you to use a do...while statement and switch statements. Write your C++ code using good style and documenting comments, and have fun thinking up some messages that will surprise the player.

3. You are working for a company that lays ceramic floor tile, and its employees need a program that estimates the number of boxes of tiles need for a job.
   
   A job is estimated by taking the dimensions of each room in feet and inches, and converting those dimensions into a multiple of the tile size (rounding up any partial multiple) before multiplying to get the number of tiles for the room.
   
   A box contains 20 tiles, so the total number needed should be divided by 20 and rounded up to get the number of boxes. The tiles are assumed to be square.
   
   The program should initially prompt the user for the size of the tiles in inches and the number of rooms to be covered with tile. It should then input the dimensions for each room in feet and inches.
   
   After the dimensions for each room have been input then calculate and output the number of tiles needed for each room, the total number of tiles needed for all rooms, the number of boxes of tiles needed, and how many extra tiles will be left over.
   
   You should create a function called TilesInRoom that will take the size of one tile, and the width and length of a room and return the number of tiles it will take to cover that room. The number of tiles should be rounded up to the nearest whole number.
   
   Here is an example of how a run might appear:
   
   Enter the number of rooms in the job:  2
   Enter the size of each tile in inches:  12
   Enter room 1 width (feet and inches, separated by a space):   17 4
   Enter room 1 length (feet and inches, separated by a space):   9 3
   Room 1 requires 161 tiles.
   Enter room 2 width (feet and inches, separated by a space):   11 6
   Enter room 2 length (feet and inches, separated by a space):   11 9
   Room 2 requires 136 tiles.
   The 2 rooms in this job will require 297 tiles.
   The number of boxes of tiles needed is 15.
   There will be 3 extra tiles left over.
   
   Note: Do not assume that the instructor will enter only 2 rooms when testing your program.
   
   

A word of caution:
