# CIS115 Exercise 7 – IPO, Flowchart, hierarchy chart, pseudocode, vb code, 5 vb screenshots

Week 7 ActivityModularized Code

TCO 3 Given a simple problem, design and desk-check a solution algorithm requiring a modular design that is expressed in terms of pseudocode or program notes, input-process-output (IPO) analysis, and flow chart.

TCO 7 Given a program with logic errors that is intended as a solution to a simple problem, employ debugging diagnostics to remove and correct the errors.

TCO 8 Given a more complex problem, develop a complete solution that includes a comprehensive statement of the problem, complete program design, and program documentation.

Assignment

Its often necessary to convert between units. In this exercise, you will create two functions for converting between units of distance. The first function will be called ConvertMilesToKilometers(), which will accept one parameter for the number of miles. It will return the equivalent number of kilometers. The second function will be called ConvertKilometersToMiles() and will accept kilometers as its parameter; this will return the equivalent number of miles.

The main method will ask the user if he or she wants to convert miles to kilometers or kilometers to miles. It will then ask for the number of miles or kilometers. It will call the appropriate method and display the converted value.

To convert miles to kilometers, divide miles by 0.62137. To convert kilometers to miles, multiply kilometers by 0.62137.

Example

Do you want to convert to Miles or Kilometers? (M or K): K

Enter number of Kilometers: 3.5

3.5 kilometers equals 2.174795 miles.

Be sure to call the correct function. Be sure to save the return value in an appropriate variable.

Be sure to think about the logic and design first (IPO chart and/or pseudocode), then code the Visual Basic program.
