Question

In this exercise, you will complete the Restaurant Tip application from Chapter 2’s Focus on the Concepts lesson. The application’s Planning Chart is shown in Figure 3-34.

1. Use either a flowchart or pseudocode to plan the btnCalc_Click procedure, which should calculate and display a server’s tip.
2. Open the Tip Solution.sln file contained in the VB2017\Chap03\Tip Solution folder. Enter the three Option statements in the Code Editor window. Use the comments as a guide when coding the btnCalc_Click procedure. Be sure to use variables in your code. Display the tip with a dollar sign and two decimal places. Save the solution and then start and test the application. (If the restaurant bill and tip percentage are 56
3. and 20, respectively, the tip is $11.20.)
4. Now professionalize your interface by coding each text box’s TextChanged and Enter event procedures. Save the solution and then start and test the application.
