Interpreter

An Interpreter is a program that translates a programming language into a comprehensible language. The interpreter converts high-level language to an intermediate language. It contains pre-compiled code, source code, etc.

  • It translates only one statement of the program at a time.
  • Interpreters, more often than not are smaller than compilers. 

Role of an Interpreter

The simple role of an interpreter is to translate the material into a target language. An Interpreter works line by line on a code. It also converts high-level language to machine language.

Interpreter

Advantages of Interpreter

  • Programs written in an Interpreted language are easier to debug.
  • Interpreters allow the management of memory automatically, which reduces memory error risks.
  • Interpreted Language is more flexible than a Compiled language.

Disadvantages of Interpreter

  • The interpreter can run only the corresponding Interpreted program.
  • Interpreted code runs slower in comparison to Compiled code.

Difference between Compiler and Interpreter

The Compiler and Interpreter, both have similar works to perform. Interpreters and Compilers convert the Source Code (HLL) to Machine Code (understandable by Computer). In general, computer programs exist in High-Level Language that a human being can easily understand. But computers cannot understand the same high-level language, so for computers, we have to convert them into machine language and make them readable for computers. In this article, we are going to see the differences between them.

Compiler

The Compiler is a translator which takes input i.e., High-Level Language, and produces an output of low-level language i.e. machine or assembly language. The work of a Compiler is to transform the codes written in the programming language into machine code (format of 0s and 1s) so that computers can understand....

Difference Between Compiler and Interpreter

Compiler                                                                   Interpreter                                                                                                              Steps of Programming: Program Creation. Analysis of language by the compiler and throws errors in case of any incorrect statement. In case of no error, the Compiler converts the source code to Machine Code. Linking of various code files into a runnable program. Finally runs a Program. Steps of Programming: Program Creation. Linking of files or generation of Machine Code is not required by Interpreter. Execution of source statements one by one. The compiler saves the Machine Language in form of Machine Code on disks. The Interpreter does not save the Machine Language. Compiled codes run faster than Interpreter. Interpreted codes run slower than Compiler. Linking-Loading Model is the basic working model of the Compiler. The Interpretation Model is the basic working model of the Interpreter. The compiler generates an output in the form of (.exe). The interpreter does not generate any output. Any change in the source program after the compilation requires recompiling the entire code. Any change in the source program during the translation does not require retranslation of the entire code. Errors are displayed in Compiler after Compiling together at the current time. Errors are displayed in every single line. The compiler can see code upfront which helps in running the code faster because of performing Optimization. The Interpreter works by line working of Code, that’s why Optimization is a little slower compared to Compilers. It does not require source code for later execution. It requires source code for later execution. Execution of the program takes place only after the whole program is compiled. Execution of the program happens after every line is checked or evaluated. Compilers more often take a large amount of time for analyzing the source code. In comparison, Interpreters take less time for analyzing the source code. CPU utilization is more in the case of a Compiler. CPU utilization is less in the case of a Interpreter. The use of Compilers mostly happens in Production Environment. The use of Interpreters is mostly in Programming and Development Environments. Object code is permanently saved for future use. No object code is saved for future use. C, C++, C#, etc are programming languages that are compiler-based. Python, Ruby, Perl, SNOBOL, MATLAB, etc are programming languages that are interpreter-based....
