CSCI101A

 

Introduction to Computer Programming using C++

Spring 2005

Lab Assignment 3

 

Step 1

 

Study the following:

 

#11 on page 222 of the 4th Edition.

 

PLEASE NOTE: there is an error in the textbook (4th ed):

Question 11 on page 222 ends after the first sentence on page 223:

. . . for illegal combinations. The next sentence: In cold weather . . .

starts the next question, Question 12. 

 

#11 on page 219 of 3rd edition

 

#11 on page 213 of 2nd edition

 

Note: you do not type in the code of your program until Step 4.

 

Step 2

 

Design an algorithm (the steps to solve the problem). You should have the algorithm approved by your instructor before going on to the next step.

The following web page will help you design your algorithm and pseudocode:

Step 3

 

Development the pseudocode from your algorithm.

The following web page will help you design your algorithm and pseudocode:

Step 4

 

Using your pseudocode as a guide, implement your program in the C++ language. Use either the Borland or Dev-C++ IDE to edit and run your program.

 

 

Your program should start with a comment block that contains the following information:

 

//  File:       lab3.cpp

//  Purpose:    #11 on page 222 of the 4th Edition.

//  Purpose:    #11 on page 219 of the 3rd Edition.

//  Purpose:    #11 on page 213 of the 2nd Edition.

//  Programmer: [your name]  

//  Partner:    [your partner's name]

//  Course:     CSCI101A

//  Date:       Thursday 27th January 2005

//  Test data:

 

Please note: any lines in a C++ program that start with the // symbols are known as comments. Comments are ignored when the program runs, but are useful when we read a program, because they supply information about the program.  They are always used at the top of a program to supply information about the purpose of a program, its file name, the programmer etc, as shown above. They are also used in the body of a program to explain parts of the program which may be hard to understand. Example programs in this course will demonstrate the correct use of comments. You are expected to supply the above set of comments (updated appropriately) for all of your lab and homework programming assignments.

 

Step 5

 

Test your program by running supplying your own test data. You should test your program with at least 3 sets of test data. Show your test data and results in comments at the top of your program.

 

Step 6

 

At the end of the class, save your program file (lab3.cpp) to your folder on the network in:

 

CSCI101A\Week04\Lab03

 

 

Program points will be based on the following marking scheme:
