Difference between Compiled and Interpreted Language

Difference between Compiled and Interpreted Language

Prerequisite – Compiler vs Interpreter

Compiled Language:
A compiled language is a programming language which are generally compiled and not interpreted. It is one where the program, once compiled, is expressed in the instructions of the target machine; this machine code is undecipherable by humans. Types of compiled language – C, C++, C#, CLEO, COBOL, etc.

Interpreted Language:
An interpreted language is a programming language which are generally interpreted, without compiling a program into machine instructions. It is one where the instructions are not directly executed by the target machine, but instead read and executed by some other program. Interpreted language ranges – JavaScript, Perl, Python, BASIC, etc.

 

Let’s see the difference between Compiled and Interpreted Language:

S.NO.	COMPILED LANGUAGE	INTERPRETED LANGUAGE
1	A compiled language is a programming language whose implementations are typically compilers and not interpreters.	An interpreted language is a programming language whose implementations execute instructions directly and freely, without previously compiling a program into machine-language instructions.
2	In this language, once the program is compiled it is expressed in the instructions of the target machine.	While in this language, the instructions are not directly executed by the target machine.
3	There are at least two steps to get from source code to execution.	There is only one step to get from source code to execution.
4	In this language, compiled programs run faster than interpreted programs.	While in this language, interpreted programs can be modified while the program is running.
5	In this language, compilation errors prevent the code from compiling.	In this languages, all the debugging occurs at run-time.
6	The code of compiled language can be executed directly by the computer’s CPU.	A program written in an interpreted language is not compiled, it is interpreted.
7	This language delivers better performance.	This languages delivers relatively slower performance.
8	Example of compiled language – C, C++, C#, CLEO, COBOL, etc.	Example of Interpreted language – JavaScript, Perl, Python, BASIC, etc.
