How is compiler compiled?

A very simple compiler can be written from an assembler and machine code.
Once you have a software that is able to translate something into binary instructions, you can use the original compiler to write a more sophisticated one (then use a second further refined one to write a third and so on)..

What is a compiler in C w3schools?

A compiler is system software (a set of a computer program) that converts source code written in a programming language (source language, usually HLL) into another computer language (target language).
It processes every statement written in a particular programming language and turns them to machine language..

Why do you need to compile code?

As a result, compiled programs often run faster and more efficiently since they are optimized for the hardware architecture they are running on.
Compilers also offer greater security benefits since human-readable source code is transformed into binary data that is much harder for someone to reverse engineer or hack..

Below, these topics are important to understand before building a compiler.

1. Code Generation and Optimization:
2. Modeling in Compiler Design and Implementation
3. Parsing (Recognition) Algorithms:
4. Syntax Directed Translation:
5. Generator grammars and semantic actions：
6. Optimizing Code:
7. Role of testing:

Stages of Compiler Design

1. Lexical Analysis: The first stage of compiler design is lexical analysis, also known as scanning
2. Syntax Analysis: The second stage of compiler design is syntax analysis, also known as parsing
3. Semantic Analysis: The third stage of compiler design is semantic analysis
