Use of Compiler

A compiler is a program that translates source code written in a programming language into machine code that can be executed by a computer. The source code is written by a programmer in a high-level programming language, such as C++ or Java, which is easier for humans to read and write. The compiler converts the source code into machine code, which is a low-level language that can be understood and executed by the computer’s processor.

There are many different types of compilers, including ones for general-purpose programming languages and ones for specialized languages used in specific fields, such as system programming or database programming.

Compilers are an essential tool in software development, as they allow programmers to write code that can be easily compiled and run on a wide variety of devices and platforms. They also provide a level of abstraction between the programmer and the underlying hardware, allowing programmers to focus on the logic of their programs without having to worry about the specific details of the hardware.

Pre-requisites: Introduction To Compilers

A compiler is a computer program that translates source code written in a programming language into machine code that can be executed by a computer. The process of translation is called the compilation process or simply compilation.

The source code is written in a high-level programming language, such as C, C++, or Java, which is easy for humans to read and write. Machine code, on the other hand, is a low-level language that consists of a series of instructions that can be directly executed by the computer’s processor.

Compilers are an essential tool for software development because they allow programmers to write code in a high-level language that is easy to understand and debug, and then translate that code into machine code that can be efficiently executed by the computer.

There are many different compilers available for different programming languages, and they typically have a number of different phases, including lexical analysis, syntax analysis, semantic analysis, code optimization, and code generation. Each phase processes the source code in a specific way and produces intermediate or final output that is used by subsequent phases.
