Anubadak

The goal of this Project was to implement a lexer, parser, interpreter and Read-Eval-Print-Loop environment for the programming language Anubadhak. Anubadhak is an expression-oriented strongly-typed programming language. It will supports C-style comments, that is, //... for single-line comments and /.../ for multiline comments, is case-sensitive, and every function is expected to return a value. There will be four data types in the language: int for integer values, real for floating point numbers, bool for Boolean values and string for string literals. C++ will be used in backend to convert the provided input text file program to the native language of the computers.

To Run this project(in Visual studio)

• first you need to download required version of wxWidget from Click here to download wxWidget
• Now search for build/msw directory in the downloaded directory
• Open your required version of visual studio solution for Visual Studio 2019 (wx_vc16.sln) then VS is opened.
• Now we need to build the wxWidget Library so build the Library in Debug configuration by clicking build.

Final step

Now you can clone this project wherever you like and Run from Visual Studio Code and you may see the Running application.

some properties of class of language accepted by anubadak

• Supports single line comment and multi line comment
• Four data types int , real, string, bool.
• Supports function overloading
• int to real auto conversion during assignment
• Supports variable scope and variable shadowing

example code to calculate cos(x) is Anubadak

// Pi
var pi : real = 3.1415926535897932;
// Cosine function
def cos(x : real) : real {
        set x=pi *x/180.0;
    // positive integer power
    def pow(x : real, n : int) : real {
        var y : real = 1;
        while(n > 0){
            set y = y*x;
            set n = n-1;
        }
        return y;
    }
    // Factorial
    def fac(n : int) : int {
        if (n == 0) { return 1; } else { return n * fac(n-1); }
    }
    // Take 8 terms of Maclaurin series for cos(x)
    var k : int = 0;
    var cos_x : real = 0;
        print("\n");
    while(k < 8){
         set cos_x = cos_x + pow( -1.0, k) * pow(x, 2*k) / fac(2*k);
         set k = k + 1;
    }
    return cos_x;
}
var angle :real=0;
while(angle<=180){
	var coss: real=cos(angle);
	print("value of cos  ( ");
        print(angle);
	print(") =");
        print(coss);
        print("\n");
        set angle=angle+30;
