Definition of Interpreter

Definition: In computing, an interpreter is a computer program that reads the source code of another computer program and executes that program.

Because it is interpreted line by line, it is a much slower way of running a program than one that has been compiled but is easier for learners because the program can bestopped, modified and rerun without time-consuming compiles.

Examples: The compiled program took ten minutes to run to completion.

The interpreted program took an hour.
