Bongo++ Compiler

Bongo++ is a custom programming language designed to simplify programming concepts while introducing a syntax inspired by the Bengali language. This repository contains the lexer and parser implementation for Bongo++, providing functionality for processing and executing programs written in this language.

Features

Supported Constructs

• Data Types:

  • purno: Integer
  • dosomik: Float/Decimal
  • sobdo: String

• Control Flow Statements:

  • Conditional statements: hoyKi (if), nahoyKi (else if), nahole (else)
  • Loops: jotokkhon (while), ChalayDen (for)
  • Switch-case: kono (switch), khetre (case), thaman (break)

• Operators:

  • Arithmetic: jog (add), biyog (subtract), gun (multiply), vaag (divide)
  • Logical: ebong (AND), othoba (OR)
  • Comparison: boro (greater than), choto (less than), soman (equal to)

• Other Keywords:

  • dhoren: Variable declaration
  • ferot: Return
  • dekhao: Print/output

Functions

• User-defined functions with parameter passing and return values.
• Example syntax for defining a function:

  purno baksho myFunction(purno a, purno b) {
      hoyKi (a boro b) {
          ferot a biyog b;
      }
      nahole {
          ferot b biyog a;
      }
  }
  

Input/Output

• Print values or messages using dekhao.
• Example:

  dekhao "Hello, Bongo++!";
  dekhao x jog y;
  

Getting Started

Prerequisites

• Install a C compiler such as GCC.
• Install Flex and Bison for lexing and parsing.

Building the Compiler

1. Clone this repository:

   git clone https://github.com/NotSOgenius69/Compiler-project.git
   cd Compiler-project
   

2. Build the project using the following commands:

   flex bongo.l
   bison -d bongo.y
   gcc -o bongo lex.yy.c parser.tab.c -lfl
   

Running a Program

1. Create a Bongo++ source file (e.g., program.bpp) with your code.
2. Execute the following command to run the program:

   ./bongo input.txt output.txt
   

Example Program

// Function definition
purno baksho addNumbers(purno a, purno b) {
    ferot a jog b;
}

purno baksho shuru() {
    dhoren purno x;
    x = 10;
    dhoren purno y;
    y = 20;

    dekhao "The sum is:";
    dekhao addNumbers(x, y);

    ferot 0;
}

Output

The sum is:
30

Future Improvements

• Adding support for advanced data structures like arrays and objects.
• Enhancing error handling for better debugging.
• Expanding the standard library with more built-in functions.
