This lab is due by Thursday, February 7, 2019, 11:59 PM. Part I - DevelopmentToday we're going to return to our math roots and compute some multiplication tables.
First, you must prompt the user to enter two numbers greater than 1 and less than 11. Continue to prompt them until they
enter two valid numbers.
To meet the specifications of Part II below, do not give any prompt such as "Enter a number". The user
will know to enter a number. But you must ensure the values are within the proper range and continue to receive input until the number
is valid.
Then output a multiplication table. You'll need to print out the column and row headers
so we know what two values are being multiplied. Then each cell will be the result of that product. Be sure to have the
numbers right aligned with enough space to have all our columns aligned. Fill the empty space with a period to ensure
the columns are properly aligned.
A sample run of the program is shown below:
112 5 1 7 .....1...2...3...4...5...6...7 .1...1...2...3...4...5...6...7 .2...2...4...6...8..10..12..14 .3...3...6...9..12..15..18..21 .4...4...8..12..16..20..24..28 .5...5..10..15..20..25..30..35 Note that the program uses the first two valid values entered as the multipier and multiplicand (5 & 7).
When developing your program, you should continually prompt the user until they enter a valid number. Then continually prompt them again until
they enter a second valid number. Also be aware that there is a newline after the final row of the table.
Hint: You'll need a couple of loops to accomplish this task. And recall, the
iomanip library
will help you with aligning the columns.Recall that the user can enter values within the range 2 to 10 inclusive, so be sure to allocate enough
space to handle a 10x10 multiplication table.
Part II - TestingTo ensure your program meets the required
specifications, log into the AutoGrader
- which must be accessed from the Mines network (so you'll need to use the VPN if at home). Log in with your multipass
account. Navigate to our course, Lab3B, multiplyTables. You will see
on the right hand side a text editor. Enter your code here. Then hit the
"Test" button in the lower left corner.
You'll see a colored bar at the top with each
segment denoting a single test. Each test provides a specific input to your program
and then compares your output with the expected output. If the bar is green, then
the test passed. If the bar is red, then the test failed and you can compare your output
with the expected output by hovering over the box. Additionally, if your code has a compiler error it
will display the error.
Once you have passed all of the tests, press the save icon
in the text editor to save your code and then hit the "Submit" button to submit
all your tests for grading. You must perform these TWO steps to receive full credit
for this lab.
You must press "Save" in AutoGrader and "Submit" with all tests passed to receive full credit for this lab.
Lab SubmissionYou will submit your solution to this lab with the rest of Set3. Detailed instructions for doing this are posted in Assignment 3. This lab is due by Thursday, February 7, 2019, 11:59 PM. | |
