Welcome to Pseudocode Pro

This site was developed to solve the problems of students either being completely stuck with pseudocode, or attempting a solution, but having no way of actually validating if it would work (other than a manual trace table). This site supports the entire Cambridge IGCSE (0478), O-Level (2210) and 9618 A-Level pseudocode specifications from the guide/syllabus, with extension modules supporting sound, canvas, events, custom html etc

Below are lists of both the currently support pseudocode and general website features:

While you are here, why not try one of the many - and ever increasing list of - pseudocode coding challenges.

To support hosting & domain costs, for $2, a premium account can be purchased - this has the following benefits:

No ads
A desktop version of the site which will load instantly & work offline
License will be valid for Assembly Code Pro too
Additional coding challenges (I will create 2 per day, will have 500 in total eventually)
Starter code & implementation of pre-defined modules for IGCSE/O-Level/A-Level past papers, so students can write and test their solutions directly, as they would in the exam

Those last 2 features are currently in progress, so an extra 3 months free will be given to anyone who buys a license now to acknowledge this

For any issues, feature requests, comments etc, you can contact me

Thanks for using the site - I hope you enjoy it and if you do, it would mean a lot if you could share it with your friends too :)

New Row

Module Call

Module Call

Will start a new line when entering a new module - e.g.

PROCEDURE a()
    //new line in trace table
    ...
ENDPROCEDURE

After Parameters

After Parameters

Will start a new line after parameters have had their values traced

PROCEDURE a(b : INTEGER)
    //b's value is traced
    //new line in trace table
    ...
ENDPROCEDURE

Loop Iteration

Loop Iteration

Will start a new line upon each iteration of a loop

REPEAT
    //new line in trace table
    ...
UNTIL index = 10

Pre Loop

Pre Loop

Will start a new line before a loop has started

//new line in trace table
REPEAT
    ...
UNTIL index = 10

Post Loop

Post Loop

Will start a new line after a loop has ended

REPEAT
    ...
UNTIL index = 10
//new line in trace table

If Statement

If Statement

Will start a new line inside an IF or ELSE condition

IF a > b THEN
    //new line in trace table
ELSE index = 10
    //new line in trace table
ENDIF

Left to Right

Left to Right

Many suggest that trace tables should be read left-to-right, top to bottom. Hence, if a value on the current row is to be updated, but a value in a column further right on the same row has already been updated, a new row should be started

If we have the column order a, b and the following assignments...

b <-- 1
a <-- 2
b <-- 3

Then the following trace table should be created (note how the assignment to 'a' has to start a new line, since we have already assigned to a variable in a column to the right ('b')

a	b
	1
2	3

Extra Options

Show Duplicates

Show Duplicates

Usually, the same value being assigned to a variable that it already contains won't be shown on a trace table - by default, it's shown by cells with a black/grey striped background. Enable this option if you'd like the value to be shown instead

a <-- 111
a <-- 111

Line Numbers

Variables to Trace:

Trace All

Hover or click to show help

Trace table only generated when this dialog is open
Specify variables & order to trace above - default is all, in order they are declared
Hovering your mouse over a cell will display the line number this value was assigned
Use BREAKPOINT keyword to pause execution at specific point
Use TRACE_NEXT_ROW to force creation of a new row at specific point
Grey/black diagonally-shaded cells indicate the value assigned is unchanged
Work in progress. Currently buggy for records, classes, sets etc - will be fixed soon :)

Re-run program for changes to take effect

Note: tokens were generated via a series of regex rules
