The difference between Compiled and interpreted Language is that interpreted languages are carried out directly by an interpreter, compiled languages are often converted into machine code prior to execution.
- Compiled and interpreted programming languages are two different primary categories in the field of programming languages.
- Languages that are compiled are typically compiled, not interpreted.
- In contrast, an interpreted language is often interpreted.

What is a Compiled Language?
[Click Here for Sample Questions]
For the purpose of transforming a high degree of language source code into low-level machine code, compiled languages employ a compiler.
- The binary file accessible Code or Obj (which is not understandable by humans) is produced by the compiler after it has gone through all of the underlying code in one pass.
- In order for processing entities to run this source code, it must be converted to machine code.
- The various forms of compiled language are as follows CLEO, COBOL, C, C++, C#, etc.
Advantages of Compiled Language
The advantages are mentioned below:
- Machine code is created by directly translating a textual language. Compiled languages can run more quickly as a result.
- Only the file that contains the executable will be distributed to others while communicating in textual languages. As a result, the source code is protected.
- A programme that has been correctly compiled or is executable is now ready to run. After you finish it, no other actions are necessary.
- Target programmes are self contained and don't need the Compiler to be active in memory to operate.
Disadvantages of Compiled Language
The disadvantages are mentioned below:
- Even with little alterations to the original source code, the entire programme has to be rebuilt. Additionally, it renders it and makes it rigid.
- To support several operating systems alongside various operating system variations, separate compiling is an essential undertaking. As a result, the compiled languages are not considered to be cross platform.
- All mistakes or cautions are shown during compilation, and if you don't correct them, the programme won't run.
- Compilation requires extensive research and takes an extensive amount of time to complete.

What is Interpreted Language?
[Click Here for Sample Questions]
Similar to a compiler, an interpreter translates automatically into machines the sources created by a compiler in a high degree language.
- The interpreter may also translate in other ways; it will read the programme alignment by alignment and execute each alignment in real time.
- "Interpreted Language" is a term used frequently to refer to programming languages that employ interpreters for translation.
- The various forms of the interpreted languages are as follows: Python, BASIC, JavaScript, Perl, etc.
Advantage of Interpreted Language
The advantages are:
- Any machine that has an interpreter installed may execute the programme. Languages used for interpreting are cross platform.
- While interpreted languages do not preserve the object's code in distinct files, they do provide dynamic typing.
- Defects are provided one line at a time, making development and testing simpler.
Disadvantage of interpreted language
The disadvantages are mentioned below:
- A compiled language takes ten times longer to execute than an interpreted language.
- Since anybody who wishes to run the programme may get the source code, it is attainable to the general.
- In order for it to work, the gadget needs a translator.

Difference between Compiled Language and Interpreted Language
[Click Here for Sample Questions]
The difference between compiled Language & Interpreted Language are tabulated below:
| Compiled Language | Interpreted Language |
|---|---|
| Programming languages are implemented using compilers, not interpreters, and are referred to as compiled languages. | A programming language is said to be "interpreted" if it has representations that carry out commands instantly and at will, despite first compiling them into machine language commands. |
| When a programme is written in this language, it becomes apparent in the target machine's commands after compilation. | The target machine does not immediately carry out the commands when they are written in this language. |
| To execute source code, a minimum of two actions must be taken. | Between the source code and execution, there is only a single step. |
| Compiler-run programmes in this language execute more quickly than interpreter-run programmes. | While using this language, translated programmes can be changed while they are being used. |
| Code cannot be compiled in this language because of compilation issues. | In these languages, all programming takes place in real-time. |
| Automatic CPU execution of compiled language code is possible. | An interpreted programme is not constructed; rather, it is interpreted. |
| This language produces improved outcomes. | This language sample performs somewhat more slowly. |
| Compiled language examples include C, C++, C#, CLEO, COBOL, etc. | JavaScript, Perl, Python, BASIC, etc. are a few examples of interpreted languages. |
Things to Remember
- There are two types of programming languages which are compiled language and interpreted language.
- The programming languages which are implemented by using compilers, not by interpreters can be defined as compiled languages.
- Some of the examples of compiled language are CLEO, COBOL, C, C++, C#, etc.
- Some examples of interpreted language are Python, BASIC, JavaScript, Perl, etc.
- A compiled language takes ten times longer to execute than an interpreted language.
- Any machine that has an interpreter installed may execute the programme. Languages used for interpreting are cross platform.
- The interpreter may also translate in other ways; it will read the programme alignment by alignment and execute each alignment in real time.

Sample Questions
Ques. What functional differences exist between compiled and interpreted languages? (2 marks)
Ans. According to their functional differences, compiled languages and interpreted languages both translate high-level programmes into machine code, but compiled languages do it all at once whereas interpreted languages do so line by line.
Ques. Why do compiled languages execute more quickly than interpreters? (2 marks)
Ans. Compiled languages execute more quickly than interpreters because compiled languages are immediately translated into machine code, which the processor can execute, they are quicker than interpreters. They therefore operate more quickly and effectively than interpreted languages.
Ques. Why do we require Interpreters and Compilers? (3 marks)
Ans. Only binary code is readable and executable by computers. High-level programming languages like C, Python, and Java are used by programmers. Since they mimic human languages and mathematical notation, such languages are simpler to use. However, high-level language code cannot be executed by computers. It must first be converted to binary code. We employ interpreters and compilers to do this.
Ques. What is a compilеd languagе? (2 marks)
Ans. A compilеd languagе is onе in which thе sourcе codе is translatеd into machinе codе or an intеrmеdiatе representation by a compilеr bеforе execution. Thе rеsulting binary codе can be directly executed by thе computеr's CPU.
Ques. What is an intеrprеtеd languagе? (2 marks)
Ans. An intеrprеtеd languagе is onе in which thе source codе is executed linе by linе or statеmеnt by statеmеnt by an interpreter. Thе intеrprеtеr rеads thе sourcе codе and еxеcutеs it without creating a separate binary or machinе codе filе.
Ques. How does thе execution process diffеr bеtwееn compiled and interpreted languages? (2 marks)
Ans. In a compilеd languagе, thе entire source codе is translated into machine codе bеforе execution. This mеans that compilation occurs bеforе running thе program. In an intеrprеtеd languagе, thе source codе is executed dirеctly without prior compilation.
Ques. What arе somе examples of compiled languagеs? (2 marks)
Ans. Examples of compilеd languagеs includе C, C++, Rust, and Fortran. Thеsе languages require a separate compilation stеp before running thе program.
Ques. What аrе somе examples of interpreted languagеs?
Ans. Examples of interpreted languagеs includе Python, JavaScript, Ruby, and PHP. Thеsе languages arе executed by interpreters that rеad and execute thе sourcе codе line by linе.
Ques. Which is fastеr, compilеd or intеrprеtеd languagеs? (2 marks)
Ans. Compiled languages arе generally fastеr at runtime bеcausе thе codе is already translated into machine codе, which can be executed dirеctly by thе CPU. Interpreted languages may havе somе overhead duе to thе intеrprеtation procеss.
