COMP 122 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

The output from your program should be structured as is displayed below:

Bill Robinson

Gross Amount: ............ $3575.00

Federal Tax: ............. $ 536.25

State Tax: ............... $ 125.13

Social Sec / Medicare: ... $ 303.88

Health Insurance: ........ $ 75.00

Net Pay: ................. $2534.75

Your program should deal with erroneous input values. Gross salary should always be a positive number. Make sure that you deal with the possibility that the user may have entered a non-numeric input value. Have your program output appropriate error messages in these cases.

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. Include steps to deal with error cases.

4. Identify three test cases, one using a positive number, and one using a negative number, and one using incorrect input (ie. Input a letter rather than a digit for the numeric input). For each of the three test cases show what inputs you will use and what your expected outputs should be.

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

Programming Problem 2

In a right triangle, the square of the length of one side is equal to the sum of the squares of the lengths of the other two sides. Stephanie has the integer lengths of three sides of a triangle and needs to know if it is a right triangle.

Write a program to solve this problem. NOTE: The user must be allowed to input the values of the sides in ANY ORDER!

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 pseudocode to solve the problem. Make sure to include steps to get each input and to report each output.

4. Identify five significant test cases including one for incorrect input (ie. Input a letter rather than a digit for the numeric input). (Think about what impact changing the order of the input values should have on your program!) For each of the five test cases show what inputs you will use and calculate what your expected outputs should be.

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