What Really Happens When You Run Your Code?
When you hit “run,” your high-level source code (say in Python, Java, or C++) goes on an adventure inside your computer. The code you write in English-like commands is first translated into something the machine can understand. If your language is compiled, a compiler performs this translation in stages. If it’s interpreted, an interpreter reads and executes your instructions on the fly. In either case, several steps – from lexical analysis (chopping code into meaningful tokens) to parsing (structuring those tokens) to generating machine code – must happen before the CPU actually executes your instructions geeksforgeeks.org en.wikipedia.org . Writing code itself usually happens in a text editor or IDE. Beginners often use friendly tools like Visual Studio Code to type and debug code https://code.visualstudio.com/ , and may consult step-by-step books such as Python Crash Course https://amzn.to/4jKRMIT or Automate the Boring Stuff with Python...
