Make a keylogger that sends keys organized to a online server/email.

I like to make programming languages :)

Here is a simple way where you can test your knowledge and work on it when you're bored

Code

using System;
using System.IO;

namespace SimpleProgrammingLanguage
{
    class Program
    {
        static void main(string[] args)
        {
            foreach(string line in args[0].Split('\n'))
            {
                if (line.ToUpper().StartsWith("WRITELINE ")) Console.WriteLine(line.Substring(10));
            }
        }
    }
}

It will read each line of the file. This example will see if the line starts with "writeline" (Case insensitive) and then writes whatever is after it

Of course, actual programming languages aren't written this way. It works more like:

Lexer > Parser > AST > Interpreter/Compiler

I can show you an actual lexer if you want me to.
