Interpreter Vs Compiler : Differences Between Interpreter and Compiler

To perform all the instructions that are written in the form of high-level languages through the use of computers, it is essential to get converted into machine language.

For this purpose, the compilers and interpreters come into play.

Both the concepts are basically used to convert the source code of a programming language into the machine ready codes. The online C++ compilers and interpreter play several useful functions for users.

Though both online compilers and interpreters may seem similar concepts, there are several points of difference between both.

To help you in this regard, we have prepared this guide where you will come across the key differences between compiler and interpreter.

Without any type of ado, let’s get started!

What is the compiler?

A compiler is touted as the translator that is known to produce the output of a low-level programming language by taking the desired input from the high-level programming language.

This is basically defined in terms of a computer program that translates any given code into machine or human readable code ranging from binary bits 0 and the bits 0f 1 for the computer processors to understand it.

The online C++ compiler is basically known to split the source code into the abstract fragment which is known as lexeme. Moreover, it also assigns the tokens to lexemes to refer to it mainly as the keywords so your desired output can be generated.

  • The online compiler is considered to be more efficient and ideal as it is helpful to check all types of errors or limits in a program
  • If the runtime of a program is more and is occupying large memory, it has to be at low speed as compiler will go through an entire program to translate it into the ideal code that is required to run a particular program

What is an interpreter?

An interpreter is basically defined as that function while performing the functions on a programming language to translate it into an ideal format. The computer program will be used to convert the high-level language statements into the machine code format.

Interpreter easily converts the program statements into machine code. And, unlike the online compiler, it takes less time to interpret your entire program.

Difference between compiler and interpreter

Compiler and interpreter are regarded among widely used programming concepts. Though both concepts may seem similar to each other, there are several points of differences between them.

Below, we have compiled some key differences between both the compiler and interpreter.

Role played


To convert the high-level language code, the computer makes use of compilers. The compilers are at the position to convert the high-level language code to that of intermediate assembly language code and then again converting it into the machine code for the assembler.


The basic role of an interpreter is to translate all the material into the machine language code. It works line by line on the code. It is also helpful in the conversion of high-level languages into the machine language so that everyone can understand it with ease.

Steps of programming


When it comes to programming, the compiler follow these below-mentioned steps:

  • First, you need to create a program
  • Analysis of the given language to reduce all the errors that may arise
  • In case there is no error, the compiler will convert the source code into the machine code
  • Then link various type of code files in the form of run program
  • Run the program


The programming steps followed by an interpreter are;

  • Firstly, create a program
  • Link all the files but the machine code is not required in this case
  • The execute the source statement simultaneously

Display of errors


In the case of a compiler, the errors are displayed or shown after they are compiled together in their current time.


Errors in the case of the interpreter are displayed after each line.

Run time


In the case of a compiler, the programs generally run faster as it easily gives output to your program to run independently from its source file.


Though, the interpreter will not give any type of output program. It can be evaluated easily after each execution is being made.



The compiler is capable of reading the whole program to search it multiple times in order to save your execution time.


There will not be any type of rigorous or strict optimization that will take place as the code evaluation procedure which may undergo line by line in a program.

Memory requirement


The compiled program in this case will be generated as the intermediate object code and then it is further needed to get the linking right. There will be more memory requirements in this case.


The program in the interpreter will not generate any type of intermediate code. So, a user may not need any extra memory.



The compiler is touted to be best bound for a special target machine. Though, it may require the same compiler on a machine to execute. C and C++ languages are considered among the most popular languages for doing the compilation process.


In the case of a web environment, compiling may take more time to run even the small codes. Hence, to run multiple codes, it can be quite tough. Load time plays an integral role in case of programming. So interpreters are more beneficial to run the program. Hence, users preferred to make use of an interpreter.

Wrapping up

Compilers and interpreters are regarded as useful programming concepts that are helpful in the conversion of source code into machine readable and understandable code.

Though, there are several key differences between both the online ide compiler and interpreter which every user should know. Take cues from this blog post to strengthen your knowledge base and implement it ideally.
