Resolved Question:

You may use a Case statement or an If/Then construct

Design an algorithm that will read two numbers and an integer code (1 – 4) from the user.
1- add
2- subtract (be sure the difference is positive)
3- multiply
4- divide (Do not find the quotient if the second number is XXXXX If the second number is XXXXX display an error message)
Any integer code number higher than 4 will also result in an error message (assume they will not input a code lower than 1).

Output: Display the selected code and the problem in equation form.

Ex: Please input the first value: 2
Please input the second value: 4
(Show the menu)
Please input a code from 1 to 4: 1

Output:
Selected code: 1
2 + 4 = 6

Please input the first value: 2
Please input the second value: 4
(Show the menu)
Please input a code from 1 to 4: 2

Output:
Selected code: 2
4 - 2 = 2

Use a For/Next loop to run the program 6 times. See page 7 of the VB notes.

Test data: values: code:
2, 4 5 Display an error message (“Please select 1-4 only”)
2, 4 1
2, 4 2
2, 4 3
2, 0 4 Display an error message (“Cannot divide by 0”)
2, 4 4

Run the program, copy the output to the bottom of the code, print out and call me over to check. Be sure to copy the program to your “G” drive location, and to your flash drive.

Be sure to use remarks for documentation; use proper spacing in code and on the screen.

Note: use the data type of Decimal for the answer so that the division problem will show a decimal answer. You may do the math and display the answer in the same block of code.
