Thread: Difference between compiler and interpreter

Here is the difference between compiler and interpreter:

Complier

• Compiler checks syntax of program

• Compiler checks at a time the entire program

• Program execution is fast

• Compiler takes entire program at a time and executes it.

Interpreter

• Interpreter checks the keywords of a program.

• Interpreter checks simultaneously in the editor.

• Program execution is quite slow.

• Interpreter executes the program line by line

A compiler first takes in the whole program, verify all errors, compiles it and after that executes it. While interpreter does this line by line, checks it for errors and after that executes it.
