A self-interpreter is a programming language interpreter written in a ... Short animation explaining the key conceptual difference between interpreters and compilers.
In computing, a compiler is a computer program that translates computer code written in one programming language (the source language) into another language (the target language). The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a low-level programming language (e.g ...
There are two general approaches to programming language implementation: [1] Interpretation: The program is read as input by an interpreter, which performs the actions written in the program. [2] Compilation: The program is read by a compiler, which translates it into some other language, such as bytecode or machine code.

Language for communicating instructions to a machine The source code for a computer program in C. The gray lines are comments that explain the program to humans. When compiled and run, it will give the output "Hello, world!". A programming language is a system of notation for writing ...
Compiler software interacts with source code by converting it typically from a higher-level programming language into object code that can later be executed by the computer's central processing unit (CPU). [6] The object code created by the compiler consists of machine-readable code that the computer can process. This stage of the computing ...
Research compilers are mostly not robust or complete enough to handle real, large applications. They are used mostly for fast prototyping new language features and new optimizations in research areas. Open64: A popular research compiler. Open64 merges the open source changes from the PathScale compiler mentioned.
Low-level programming languages, such as assembly and C, are typically compiled, especially when efficiency is the main concern, rather than cross-platform support. For such languages, there are more one-to-one correspondences between the source code and the resulting machine code , making it easier for programmers to control the use of hardware.
In programming it is common to use the programming language name to refer to both the compiler and the programming language, the context distinguishing the meaning. A C++ program is compiled using a C++ compiler. That also applies in the following. For example, META II is both the compiler and the language.
