Difference between Compiler and Interpreter

Published on 07 Mar 2020

A compiler or an interpreter is a program that converts a program written in a high-level language into machine code understood by the computer. The major differences between a compiler and interpreter are given below.


Difference between Compiler and Interpreter

 

CompilerInterpreter
1) A compiler converts the whole program to machine language directly.1) An interpreter translates the high-level language program one line at a time to some intermediate form and then executes that converted line. The next line is then executed and so on.
2) The converted program can be stored somewhere in memory and this .exe file can be executed without requiring the presence of a compiler2) The presence of an interpreter is a must while executing the program.
3) Complex software.3) Usually smaller and simpler software.
4) Execution of program can start only if the code is free of errors.4) Execution continues until an error is found.
5) Faster, because only once the .exe file is generated and for future executions, this file is used.5) Slower, as conversion of source code to machine code is done for every execution.
6) A compiler is Machine dependent. The object code generated for one machine cannot be used for another machine.6) An interpreter generates machine-independent code.
7) The programming language like C, C++ use compilers.7) The programming language like Python, Ruby use interpreters.
