Open notes, open internet, open VB IDE (you may try out your answer in a program before you submit it), you may ask me for clarification, you may NOT ask me for the answers, likewise you may NOT ask another student Quiz Part II - Design, write, create, test, run, and save a Visual Basic program to determine the Greatest Common Denominator between two input numbers. GCD is found by determining the highest number that divides evenly into both of the two input numbers. For instance: given num1 = 12 and num2 = 18 then gcd = 6 given num1 = 12 and num2 = 21 then gcd = 3 given num1 = 12 and num2 = 24 then gcd = 12 given num1 = 12 and num2 = 28 then gcd = 4 given num1 = 28 and num2 = 12 then gcd = 4 Run a loop. Stop when you reach the smaller number. Keep track of whenever you find a number that divides evenly into both input numbers: Call your form "frmGCD.frm" and your project "vbGCD.vbp" Think before you start What form objects will you use? What variables will you use? What processes will you use? How do you determine a denominator? How do you determine the greatest common denominator? Test frequently Save frequently When complete, copy to your "H:/VB" folder so I can grade it Grading Criteria: Form must be named Form objects (except labels) must be named You must have your name, date, and program name as comments at the top of the code You must use "Option Explicit" Variables must be named and declared Exit button must ask if I really want to exit Determine button must provide the correct answer to all test input. I will test with the numbers given above Output must echo user input so that the user can see and fix his own misteaks Output must show the correct answer Use enough text in the output to describe what the numbers mean Open online book, open notes, you may ask clarification questions but I will not code this for you, you may NOT ask your fellow students for help Take as much time as you need to get it right If we have time, we'll complete the vbStars loop practice program from yesterday on the board together HAVE A GRAND WEEKEND!!!

Use NOT to reverse the logic: NOT TRUE NOT FALSE NOT intMesRet = vbNo NOT strQuitGame = vbYes Use OR to compare two possible answers to the same variable: strDirection = "up" OR strDirection = "down" strAnswer = "YES" OR strAnswer = "yes" intAge = 17 OR intAge <> 17 strHaveCar = "Y" OR strHaveCar = "y" dtmDay = "Saturday" OR dtmDay = "Sunday" OR blnHoliday = TRUE isNumeric(txtNum1.text) OR isNumeric(txtNum2.text) strHaveCar = "Y" OR strHaveRide = "Y" OR strBusRide = "Y" strTrafficLight = "Yellow" OR strTrafficLight = "Red" or strTrafficSign = "Stop" strTrafficLight = "Red" OR blnCarInFrontOfYou = TRUE Use AND to compare two possible answers to different variables: strDirection = "up" AND strAnswer = "yes" strAnswer = "YES" OR strAnswer = "yes" intAge >= 17 AND strHaveCar = "Y" dtmDay = "Monday" AND blnHoliday = TRUE isNumeric(txtNum1.text) AND isNumeric(txtNum2.text) strTrafficLight = "Yellow" AND blnJustTurnedYellow = FALSE strTrafficLight = "Yellow" AND intTurnedYellowSeconds > 5 strTrafficLight = "Green" AND blnCarInFrontOfYou = FALSE cmdTopLeft <> "" AND cmdTopLeft = cmdTopCenter AND cmdTopCenter = cmdTopRight Use complex logic and PEMDAS to compare different combinations of answers: strHaveCar = "Y" AND strHaveLicense = "Y" OR strBusRide = "Y" blnSchoolOpen = TRUE AND strHaveRide = "Y" OR strBusRide = "Y" blnSchoolOpen = TRUE AND (strHaveRide = "Y" OR strBusRide = "Y") Lab Assignment - Finish "vbStars.vbp" from Wednesday Create a Visual Basic program to display a times table chart. Give the user the option of starting and stopping at different numbers. Give the user the choice of a multiplier. Sample output for start number 5, stop number 9, and multiplier 2: 5 times 2 is 10 6 times 2 is 12 7 times 2 is 14 8 times 2 is 16 9 times 2 is 18 Open Visual Basic and create a new executable Name the form "frmTimesTable.frm" and the project "vbTimesTable.vbp", saved to your documents VB folder Always add labels to identify any input text boxes Add variables: Option Explicit Dim intMesRet As Integer ' message box return variable Dim intStartNum As Integer ' number to start at Dim intStopNum As Integer ' number to stop at Dim intMultiplier As Integer ' number to multiply by Dim intProduct As Integer ' answer from multiply by Dim intRows As Integer ' a loop control sentinel variable Dim intCols As Integer ' another loop control sentinel variable Add a command button "cmdExit" and logic to exit Add textboxes for start number "txtStartNum", stop number "txtStopNum", and multiplier "txtMultiplier" Add a picture box for output Add a command button "cmdList" to display a times table list Double-click the command button to open the code window and a sub-routine "cmdList_Click()" Clear the output picture box Test each textbox, if numeric, change to value and assign to the correct variable Build a loop, start at the start number and stop at the stop number Inside a loop, get the product by multiplying the sentinel variable by the multiplier and display the output to the picture box Save frequently Test Modify the "vbTimesTable.vbp" Visual Basic program to draw a table in addition to a list. Use numbers across the top and down the side. Display the product of the two numbers in a table in between. For example: 1 2 3 1 1 2 3 2 2 4 6 3 2 6 9 Add a command button "cmdTable" Double-click the command button to open the code window and a sub-routine "cmdTable_Click()" Test each textbox, if numeric, change to value and assign to the correct variable Use a loop to display the header row from start number to stop number. Use "intCols" as your sentinel variable. Use the semi-colon character to stay on the same line of output: picOutput.Print " " & intCols; Print nothing to move to a new line after the loop ends Use another loop for each row, start at the start number and stop at the stop number. Use "intRows" as your sentinel variable in the first "outside" loop Inside this first "outside" loop, display the row number. Then you need a second "inside" loop to display columns. Use "intCols" as your sentinel variable in the second "inside" loop Inside the second loop, get the product by multiplying the sentinel variable by the multiplier and display the output Use the semi-colon character to stay on the same line of output: picOutput.Print " " & intRows; picOutput.Print " " & intProduct; End the second "inside" "intCols" loop Print nothing to move to a new line after the second "inside" "intCols" loop ends End the first "outside" "intRows" loop Go back and use blank spaces to line up the output numbers Save frequently Test
