Week 1 iLab - Part 1

Follow the instructions in COMP 122_W1_iLab_Part1_instructions.docx.

COMP 122

Week 1 iLab - Part 2

Complete the following two programs:

Programming Problem 1

John wants to know the values of the area and perimeter of a rectangle. John can take measurements of the length and width of the rectangle in inches. John's measurements are expected to be accurate to within 0.1 inch.

1. Identify the inputs and outputs of the problem.

2. Identify the processing needed to convert the inputs to the outputs.

3. Design an algorithm in pseudo code to solve the problem. Make sure to include steps to get each input and to report each output.

5. Write the program to implement your algorithm. Test your program using your test cases. Did your program produce the values predicted in your test cases? Explain.

Week 2 iLab

Complete the following two programs:

Programming Problem 1

Write a program that calculates and outputs the monthly paycheck information for an employee, including all the amounts deducted from an employee’s gross pay, and the net pay that is due to the employee. The user of your program will know the employee’s name and the gross pay for the employee. Each employee has the following deductions taken from his gross pay:

Federal Income Tax: 15%

State Tax: 3.5%

Social Security + Medicare Tax: 8.5%

Health Insurance \$75

Week 3 iLab

Complete the following two programs:

Programming Problem 1

Write a program that generates all the factors of a number entered by the user. For instance, the number 12 has the factors 2 * 2 * 3. This program has the following requirements:

A. The user must enter a positive integer. If the user enters something else, your program should output an error message and let the user enter a new value. Use a do/while loop to make sure the user input is successful.

B. The factors must be output in increasing order. The lowest factor your program should report is 2.

C. Your program should output 4 factors per line, each factor in a field of 10 characters. (Hint: the number of factors output determines when to output endl!)

D. You will need a while loop to report the factors. Here are some helpful hints:

1. If (a % b == 0) then a is a factor of b.

2. When you have found a factor, output the factor and then reduce the number you are working with by dividing the number by the factor… ie) / a;

1. Design an algorithm in pseudocode to solve the problem. Make sure to include steps to get each input and to report the output. Include steps to deal with error cases as specified above.

2. Identify three test cases, one using a number with 4 factors, one using a negative number, and one using a number with more than 4 factors. For each of the three test cases show what inputs you will use and what your expected outputs should be.

3. Write the program to implement your algorithm. Test your program using your test cases.

COMP 122 Week 4 Lab Part 1

Part 1 of this week’s lab will give you an opportunity to use the debugging capabilities of Visual Studio. Part 2 will present a problem for which you will need to create a test plan and actually test an executable program to determine if it behaves correctly.

Part 1 – Using the Debugger

To begin this exercise, create a VC++ project and copy the following code into your project. Make sure that the project compiles successfully.

#include

using namespace std;

int main()

{

int input;

int , ;

int ;

cout< "enter="" which="" number="" in="" the="" fibonacci="" number="" sequence="" you="" want="" to="" find."=""><endl;="">

cout< "the="" first="" and="" second="" fibonacci="" numbers="" are="" 1."=""><endl;="">

cin>> input;

while (input < 1)="">

Week 5 iLab

Objectives

Apply structured and modular design principles to write programs that meet written specifications and requirements. Develop a pseudo-code design using appropriate program structure (sequence, selection, repetition and nesting) to solve a given programming problem. Use appropriate selection and repetition statements to implement the design. Create user-defined functions to implement a modular design. Use appropriate parameter passing mechanisms for passing data into and getting data back from functions. Use ostream and iomanip formatting manipulators to display tabulated data. Design and implement a menu-driven interface.

Problem Description

This program is to give the user the option of converting a set of temperatures either from Celsius to Fahrenheit (C to F) or vice versa, from Fahrenheit to Celsius (F to C), or to quit the program. If the user selects either C to F or F to C, the program will prompt the user to enter three integer values, a starting temperature, an ending temperature, and an increment. After these values have been entered the program will display a table of equivalent C and F (or F and C) temperatures, from the starting temperature to the ending temperature and incrementing by the increment value each row.

Week 6 iLab

You are to design a program that will allow some number of grades (up to a max of 100) to be input by the user. After the data has been collected, your program should calculate and output the mean and median of the collected data, as well as the sorted grade information.

Design Constraints

Use an integer constant of 100 to specify the number of elements in the array you will use to collect the grade information. Do not use any global variables in your program. Declare any arrays you need in your main function and pass the arrays as needed into the functions described below. The main function is the only function permitted to do any output to the console!!! Do not do cout operations inside of any other function. Your data collection loop in your main function must allow the user to enter less than 100 grades. It must also make sure that the user does not try to enter more than 100 grades. Each data value entered should be checked to make sure it is between 0 and 100. Any other value entered should be considered invalid and ignored (ie. not counted as a valid input and not stored in an array). Once the data is collected, the array and the number of grades collected must be passed to a function called mean. The mean function must loop through the values in the array, summing them together. The result of the function is the sum divided by the number of grades collected.

Week 7 iLab

The focus of this lab is on using strings. You will have an opportunity to work with both C style strings and the string data type. This lab also gives you an opportunity to use what you have learned previously, including using functions, array processing, repetition, and selection. You will also have an opportunity to work with file input and output.

You are to design and implement a program which does encryption and decryption of data from files. Encryption is the process of taking plain lines of text and performing some algorithmic transformation on the data to create an encrypted line of text which looks nothing like the original. Decryption is the process of taking an encrypted line of text and performing some algorithmic transformation on the data to recover the original line of plain text.
