��� Lab # CIS CIS170C-A5

��� Lab 5 of 7: Arrays and Strings

��� Lab Overview – Scenario/Summary

You will code, build, and execute two programs requiring arrays and strings.

First program (Video Game Player Program): Determine the average score for a group of players and then determine who scored below average.

Second program (Pig Latin): Convert words in a phrase to pig latin.

Learning outcomes:

��� Be able to explain the need for arrays in a program.
��� Be able to determine the appropriate array data type to use in a given program.
��� Be able to write a program that implements arrays.
��� Be able to explain��the way memory is allocated for arrays in a program.
��� Be able to explain the fact that arrays are objects in C++.
��� Be able to write a program that implements strings.

��� Lab Steps

Preparation:
If you are using the Citrix remote lab, follow the login instructions located on the iLab tab in Course Home.

Locate the Visual Studio 2010 icon and launch the application.

Lab:

Part A: Video Game Player Program
Step 1: Requirements
Write a program to do the following:

In main, declare a PlayerName Array and a Score Array. Declare the size of the arrays to be 100.

In the InputData function, input the player name and score into the arrays for an unknown number of players up to 100.

In the DisplayPlayerData function, display the name and score of each player.

In the CalculateAverageScore function, calculate the average score and return it by value.

In the DisplayBelowAverage function, display the name and score for any player who scored below the average. Do not use global variables.

Output from Program:

Enter Player Name (Q to quit): Bob
Enter score for Bob: 3245
Enter Player Name (Q to quit): Sue
Enter score for Sue: 1098
Enter Player Name (Q to quit): Dave
Enter score for Dave: 8219
Enter Player Name (Q to quit): Pat
Enter score for Pat: 3217
Enter Player Name (Q to quit): Q

Name Score
Bob 3245
Sue 1098
Dave 8219
Pat 3217

Average Score: 3944.75

Players who scored below average
Name Score
Bob 3245
Sue 1098
Pat 3217
Press any key to continue . . .

Step 2: Processing Logic
Using the pseudocode below, write the code that will meet the requirements.

Main Function
Declare the player name and score arrays, number of players, and average score.

Call the InputData function
Call the DisplayPlayerData function
Call the CalculateAverageScore function and assign the returned value in average score
Call the DisplayBelowAverage function

InputData function
While the number of players is less than the length of the array
Prompt for the player’s name
If the user entered Q, break out of the loop
Prompt the user for the player’s score
Add 1 to the number of players
End-While

DisplayPlayerData function
Display the name and score of each player

CalculateAverageScore function
Add up the scores and divide by the number of scores to calculate the average score
Display the average score
Return the average score to main

DisplayBelowAverage function
Display the names and scores of all players who scored below the average score

Step 3: Create a New Project
Create a new project and name it LAB5A. Write your code using the Processing Logic in Part A, Step 2. Make sure you save your program.

Step 4: Compile and Execute
��� Compile your program. Eliminate all syntax errors.

��� Build your program and verify the results of the program. Make corrections to the program logic if necessary until the results of the program execution are

what you expect.

Step 5: Print Screen Shots and Program

��� Capture a screen print of your output. (Do a PRINT SCREEN and paste into an MS Word document.)
��� Copy your code and paste it into the same MS Word document that contains the screen print of your output.
��� Save the Word document as Lab05A_LastName_FirstInitial.

END OF PART A

Part B: Pig Latin
Step 1: Requirements
Write a program that will input a phrase and convert it to pig latin. Put each word in a separate element of a string array. Remove the first letter from each word and

concatenate it to the end of the word followed by ���ay.���

Sample Output from Program:
*****************************************************
* You will be prompted to enter a string of *
* words. The string will be converted into *
* Pig Latin and the results displayed. *
* Enter as many strings as you would like. *
******************************************************

Enter a group of words or ENTER to quit: Computer Programming is fun to learn!

Original words: Computer Programming is fun to learn!
New Words: omputercay ogrammingpray isway unfay otay earnlay!

Enter a group of words or ENTER to quit: Quit

Pig Latin Hint:
If a word begins with one or more consonants, move the consonant or consonant cluster to the end of the word. Add the letters “ay” to the end of the word. So, “pig”

would be “igpay,” and ���latin��� would be ���atinlay.���

Step 2: Processing Logic
Using the pseudocode below, write the code that will meet the requirements.

Main function
Display the heading
While the condition is true
Prompt the user for group of words or Enter to quit
Display original words
Call function pigLatinString( )
End while

pigLatinString( ) function
Declare and initialize string variables len, counter, start, begin, word and newString
While condition is true
Call find() and pass a space and start as parameters and return the returned value
to start
if start equals to string::npos
jump outside the loop permanently
call substr() function
display the word
update newString
increment start by one
assign start to begin
End While
Call substr()
Update newString
Return newString

Step 3: Create a New Project
Create a new project and name it LAB5B. Write your code using the Processing Logic in Part B, Step 2. Make sure you save your program.

Step 4: Compile and Execute
��� Compile your program. Eliminate all syntax errors.

��� Build your program and verify the results of the program. Make corrections to the program logic if necessary until the results of the program execution are

what you expect.

Step 5: Print Screen Shots and Program

��� Capture a screen print of your output. (Do a PRINT SCREEN and paste into an MS Word document.)
��� Copy your code and paste it into the same MS Word document that contains the screen print of your output.
��� Save the Word document as Lab05B_LastName_FirstInitial.
