IGCSE CS PseudoCode Transpiler

This program translates the Pseudocode syntax studied in the IGCSE Computer Science 0478/0984 Syllabus.

Note

Prerequisites

Python 3

How to use

Syntax

For starters, it is required to leave a space character between each variable, function or operator. For example, when assigning a value to a variable, this is the correct way to do it.

variable = 16 * 14 + variable2

While this, on the other hand, will not work.

variable=16*14+variable2

Arrays (example):

Numbers = [ 3, 4 ]
Numbers[Count] = 123
INPUT Numbers[3]

Available Functions

PRINT (Fully functional):

This is a simple statement use as in the following examples

PRINT "HELLO WORLD !"

The OUTPUT keyword also works

OUTPUT "HELLO WORLD !"

To print the string between two quotation marks " ".

Note that you should *never put quotations within pre-existing quotations and/or use a backslash character "\".

It is also possible to print/output the contents of a variable.

PRINT Variable

The OUTPUT keyword also works

OUTPUT Variable

To print multiple strings, or variable or both, separate them using commas. sum = 99

PRINT "The sum is equal to:" , sum

Output: The sum is equal to: 99

Note that spaces are automatically added between printed entites

INPUT (Fully functional):

This is a simple statement that can be used as in the following example.

INPUT Variable

The keyword, "USERINPUT", can also be used.

Variable = USERINPUT

IF (Fully functional):

A conditional statement that carries out a number of statements between the IF statement and the ENDIF statement. The ELSE statement will also be functional.

IF I = T THEN
PRINT "HELLO WORLD !"
I = I + 1
ELSE
"Print Hello"
ENDIF

(The 'THEN' keyword is optional)

FOR Loop (Fully functional):

This is to repeat a number of statements, which are inserted between the FOR "LCV" = "Start" TO "End" and the NEXT "LCV", for a set number of times.

FOR I = 1 TO 5
PRINT "HELLO WORLD !"
NEXT I

WHILE Loop (Fully functional):

A conditional loop that is repeated as long as a condition is true. Any statements should be inserted between the WHILE "Condition" and the ENDWHILE STATEMENT.

WHILE I < 5 DO
PRINT "HELLO WORLD !"
I = I + 1
ENDWHILE

(The 'DO' keyword is optional)

REPEAT Loop (Fully functional):

A conditional loop that is repeated until a certain condition is met. Any statements should be inserted between the REPEAT and the UNTIL statement.

REPEAT
PRINT "HELLO WORLD !"
I = I + 1
UNTIL I = 5

Commenting (Functional):

Comments should be preceded by two slashes and a space character as follows.

// This is a comment
