  • What is the structure of the compiler design?

    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..

  • What is your idea about compiler design?

    Compiler Design is the structure and set of principles that guide the translation, analysis, and optimization process of a compiler.
    A Compiler is computer software that transforms program source code which is written in a high-level language into low-level machine code..

How to do syntax analysis using yacc?

To write a c program to do exercise on syntax analysis using YACC.
YACC (yet another compiler) is a program designed to produce designed to compile a LALR (1) grammar and to produce the source code of the synthetically analyses of the language produced by the grammar.
Start the program.
Write the code for parser. l in the declaration port.

How to implement the back end of a compiler using a C program?

AIM:To implement the back end of a compiler which takes the three address code and producesthe 8086 assembly language instructions using a C program.
ALGORITHM:Step 1:

  • Start the program.
    Step 2:Include the necessary header files.
    Step 3:Declare necessary character arrays for input and output and also a structure to include:it.
