Introduction

Programming++ is a cross-platform, object-oriented scripting language. It is a small and lightweight language. Inside a host environment (for example, a desktop application), Programming++ can be connected to the console application to provide programmatic control over them.

Programming++ is a general-purpose programming language created by Abir Abedin Khan as an extension of the Programming++ is (.progpp). The language has expanded significantly over time. This language is developed in python.

What you should already know

This guide assumes you have the following basic background:

A general understanding of Programming Language.
Good working knowledge in computer.

Hello world

To get started with writing Programming++, open the Scratchpad and write your first "Hello world" Programming++ code:

PRINT("Hello World")

Save this file in the console file as .progpp then open shell.exe then write RUN("filename.progpp")

Variables

You use variables as symbolic names for values in your application. The names of variables, called identifiers, conform to certain rules.

To Indicate a variable in programming++ you need to write first capital VAR then your var name and = your variable.
Example- VAR a = 1525 VAR b = 2558 PRINT(a+b)

if...else statement

Use the if statement to execute a statement if a logical condition is true. Use the optional else clause to execute a statement if the condition is false. An if statement looks as follows:



IF </expr> THEN
	<expr>
	<expr>
	<expr>
	<expr>
	<expr>
ELSE 
	<expr>
	<expr>
	<expr>
	<expr>
	<expr>
END	

#######OR#######
IF <codition> THEN <expression> ElSE <expression>

condition can be any expression that evaluates to true or false. See Boolean for an explanation of what evaluates to true and false. If condition evaluates to true, statement_1 is executed; otherwise, statement_2 is executed. statement_1 and statement_2 can be any statement, including further nested if statements.

You may also compound the statements using else if to have multiple conditions tested in sequence, as follows:


IF <expr> THEN
	<expr>
	<expr>
	<expr>
	<expr>
	<expr>
ELIF <expr> THEN
	<expr>
	<expr>
	<expr>
	<expr>
	<expr>
END
#######OR#######

IF <codition> THEN <expression> ElIF <codition> THEN <expression>

In the case of multiple conditions only the first logical condition which evaluates to true will be executed. In general, it's good practice to always use block statements, especially when nesting if statements:



IF </expr> THEN
	<expr>
	<expr>
	<expr>
	<expr>
	<expr>
ELSE
	<expr>
	<expr>
	<expr>
	<expr>
	<expr>
END	

#######OR#######
IF <codition> THEN <expression> ElSE <expression>

while statement

A while statement executes its statements as long as a specified condition evaluates to true. A while statement looks as follows:


        
      WHILE <codition> THEN <expr>
     #######OR#######
     WHILE  <codition> THEN
          <expr>
          <expr>
          <expr>
          <expr>
          <expr>
    END

If the condition becomes false, statement within the loop stops executing and control passes to the statement following the loop.

The condition test occurs before statement in the loop is executed. If the condition returns true, statement is executed and the condition is tested again. If the condition returns false, execution stops and control is passed to the statement following while.

Function declarations

A function definition (also called a function declaration, or function statement) consists of the function keyword, followed by:

FUN <Name>()
Now write your expression
Now end your function with END

For example, the following code defines a simple function named square:


FUN <name>() -> <expr>

FUN <name>()
	<expr>
	<expr>
	<expr>
	<expr>
	<expr>
END
