Compiler vs Interpreter (Day - 03)


Compiler vs Interpreter:-


🟦 What Is a Compiler?

A compiler translates your entire program into machine code before running it. It creates an executable file that can be run later without needing the original code.

Key Features:

  • Converts the whole code at once
  • Creates a separate executable file
  • Faster execution
  • Errors are shown only after full compilation

🟢 Example: Languages like C or C++ use compilers. You write code → compile → run the .exe file.


🟩 What Is an Interpreter?

An interpreter reads and runs your code line by line, without creating a separate file. It’s great for beginners because errors are shown immediately.

Key Features:

  • No separate file created
  • Easy to debug
  • Slower than the compiler
  • Shows errors immediately

🟣 Example: Languages like Python, JavaScript, and Ruby use interpreters. You write code → run → see output instantly.
