In a compiler, linear analysis is called lexical analysis or scanning and is performed by the lexical analyzer or lexer. The most common and likely wellknown data structure is the array, which contains a contiguous collection of data items that can be accessed by an ordinal index. The compiler has two modules namely front end and back end. Symbol table is an important data structure created and maintained by compilers in order to store information about the occurrence of various entities such as variable names, function names, objects, classes, interfaces, etc. By specifying a target data structure as a composition of components from a reuse library, the p2 compiler replaces abstract operations with their concrete implementations. Adata structure compiler is a suite of tools that reduces the burden of programming data structures. Predator is a data structure precompiler that generates efficient code for maintaining and querying complex data structures. But avoid asking for help, clarification, or responding to other answers. A compiler is a computer program that translates computer code written in one programming language the source language into another language the target language.
There have been several attempts to produce such compilers. If individual data members in a structure are not packed, the compiler can add padding within the structure for faster access to individual members, based on the natural alignment of each member.
