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. assembly language, object code, or machine code) to create an executable program.

There are many different types of compilers which produce output in different useful forms.

A cross-compiler produces code for a different CPU or operating system than the one on which the cross-compiler itself runs.

A bootstrap compiler is often a temporary compiler, used for compiling a more permanent or better optimised compiler for a language.

A program that translates from a low-level language to a higher level one is a decompiler.

A program that translates between high-level languages, usually called a source-to-source compiler or transpiler.

A language rewriter is usually a program that translates the form of expressions without a change of language.

A compiler-compiler is a compiler that produces a compiler (or part of one), often in a generic and reusable way so as to be able to produce many differing compilers.

A compiler is likely to perform some or all of the following operations, often called phases: preprocessing, lexical analysis, parsing, semantic analysis (syntax-directed translation), conversion of input programs to an intermediate representation, code optimization and machine specific code generation.

Compilers generally implement these phases as modular components, promoting efficient design and correctness of transformations of source input to target output.

Program faults caused by incorrect compiler behavior can be very difficult to track down and work around; therefore, compiler implementers invest significant effort to ensure compiler correctness.

Compilers are not the only language processor used to transform source programs.

An interpreter is computer software that transforms and then executes the indicated operations.

The translation process influences the design of computer languages, which leads to a preference of compilation or interpretation.

In theory, a programming language can have both a compiler and an interpreter.

In practice, programming languages tend to be associated with just one (a compiler or an interpreter).

i am very thankful to you . you have completed my whole doubts and increase my desire of learning. i really requested to you always continue to your services...
thanks a lot.

What are the steps involved in an interpreter can you please explain

[amirthaakarthikanagamuthu]

Mam explain about programming paradigm

Thanks for tNice tutorials content. It was the first soft soft video I've seen that didn't assu I knew my way around all of the functions.
