What are the classification of compilers?
Majorly, there are three types of compilers: Single Pass Compilers.
Two Pass Compilers.
Multipass Compilers..
What is compiler in compiler design?
A compiler is a special program that translates a programming language's source code into machine code, bytecode or another programming language.
The source code is typically written in a high-level, human-readable language such as Java or C++..
What is the science of building a compiler?
In compiler design, modeling is a useful tool for representing the behavior of a compiler.
Modeling can be used to model the language, its syntax and semantics, how it transforms source code into machine code (or vice versa), and even how it interacts with other compilers or programs that use the same language..
What is the structure of the compiler?
The compiler has two modules namely the front end and the back end.
Front-end constitutes the Lexical analyzer, semantic analyzer, syntax analyzer, and intermediate code generator.
And the rest are assembled to form the back end.
It is also called a scanner..
Which phase of the compiler is also known as scanner?
The first phase of the compiler is the lexical analyzer, also known as the scanner, which recognizes the basic language units, called tokens.
The exact characters in a token is called its lexeme..
- The primary and main function of a Compiler is to translate source code from a high-level programming language to a lower-level language like object code.
A compiler creates a machine code that runs on a processor with a specific Instruction Set Architecture (ISA), which is processor-dependent.
