Making the transition from the algorithm to the implementation (C++ code).

What is ProgramPad ?

• ProgramPad is a component of the AlgoTutor system

• It converts your algorithm developed in Composer of AlgoTutor into C++ code.

• To use the ProgramPad, you need to first develop an algorithm for a given problem.

How to use ProgramPad

For a new problem 1. Start with an AlgoTutor problem

exercise2. Solve the AlgoTutor problem3. Select the Corresponding

ProgramPad exercise

For a problem for which you have already developed an algorithm

1. Simply select a ProgramPad exercise

How to use ProgramPad (for a new problem)

Step 1: Start with an

AlgoTutor problem exercise

Step 2: Solve the AlgoTutor problem

How to use ProgramPad (after you have developed an algorithm)

Click “Solve” !

You can now see your algorithm turned into C++ code!!

January 13, 3:35 PM

The first time you use ProgramPad for a problem you will need to load your algorithm

January 13, 3:35 PM

To load your algorithm, (1)click the drop down arrow (2) select your algorithm (AlgoTutor

solution), then (3) click the load button

The C++ code corresponding to your algorithm is in this pane

This pane contains the statements that need to be at the beginning of a

C++ program

Your program variables are in this pane

Your algorithm does not contain C++ syntax, so you

may need to add some things. For instance, this one is

missing variable declarations

After typing the appropriate C++ code in this pane, you need to click

The Save button. Then you can compile your program by clicking

the Build button.

If your C++ syntax

is correct, then you will see this

notice.

Now you can select the data to run you

program with, or use your input

Now click the Run buttonto execute

your program

The results of your run will show up in a popup window.Notice any errors,then click close.

In the preceding run, the spacing was off and

there was no purpose printed. So the solution can be altered by typing

in the solution pane

After clicking Save, Buildand Run, the new results

are better.

You want to test with your own input values?

You want to print code ?

Click “Print” !

If you do not see a new pop

window, click here to minimize

this window

OrClick here on the

task bar

Click here to print!

Pop-up window for printing your code

You are all done, so don’t forgetto click the Done

button.Make sure you print before

You click done.

You have now successfully completed a ProgramPad exercise!
