What is the difference between Compiler and Interpreter?

o    Compiler:

       A compiler is a program that translates program (called source code) written in some high level language into object code.A compiler translates high-level instructions directly into machine language and this process is called compiling.

·          Interpreter:

        An interpreter translates high-level instructions into an intermediate form, which it then executes. Interpreter analyzes and executes each line of source code in succession, without looking at the entire program; the advantage of interpreters is that they can execute a program immediately
