Understanding the Compiler and Interpreter

A Compiler and an Interpreter are both used to convert high-level programming code into machine language.
They work differently in how and when they translate the code.

Compiler :

• Compiler translates the entire code into machine code at once.
• It converts high level code into executable files.
• After compilation, the program can run without using compiler.
• Compilation usually takes time before execution starts.
• If any error occurs in entire code it will shown after the whole code is compiled.
• It makes the programs run faster after compilation.
• Compiler check the entire code for syntax error at once.
• Once compiled, you can run the program multiple times quickly.
• It is suitable for large programs that require performance.
• Examples of compiled languages: C, C++, Java.

Interpreter :

• An interpreter translates and runs code line by line.
• It doesn’t create a separate executable file.
• The program runs directly, starting from the first line.
• If any error occurs in entire code it will shown immediately when the faulty line runs.
• It is slower than a compiler because it translates in real-time.
• Interpreted code is easier to test and debug.
• Code needs the interpreter every time it runs.
• It’s great for beginners and quick script testing.
• It’s ideal for small programs and learning purposes.
• Examples of interpreted languages: Python, JavaScript, PHP.

Conclusion :
Both compiler and interpreter have their own advantages based on the use case.
Understanding their differences helps in choosing the right tool for programming.
