Interpreter

What Interpreter Means?

Interpreter is also a language translator that translates a source code(.c) into a machine code(.obj). But it converts only one source code instruction to a machine code instruction at a time. Therefore a compiler processes the entire program in one go while interpreter processes one instruction at a time.

Error In Source Code

The interpreter checks for errors in each source code instruction and indicates it to the programmer instantly. Thus clearing errors for a programmer is not that much headache. As interpreter execute the instruction, only after the error in a instruction is corrected. This process continues until the last line of a program is reached.

How Interpreter Works

Interpreter replaces a single statements to a single machine language instruction at a time. A single statement is a line terminated by semicolon. The following diagram clearly demonstrate how interpreter translate source code to a machine code.
