Explain What is a compiler?  \nA compiler is a program that reads a program written in one language –the source language and translates it into an equivalent program in another language-the target language. The compiler reports to its user the presence of errors in the source program.  \n2. What are the two parts of a compilation? Explain briefly.  \nAnalysis and Synthesis are the two parts of compilation.  \n1. The analysis part breaks up the source program into constituent pieces and creates an intermediate representation of the source program.  \n2. The synthesis part constructs the desired target program from the intermediate representation.  \n\n| |  |\n| --- | --- |\n\n[http://engineeringinterviewquestions.com/compiler-design-questions-answers/ 1/20](http://engineeringinterviewquestions.com/compiler-design-questions-answers/ 1/20)  \n3/19/2019 100 TOP COMPILER DESIGN Important Questions and Answers Pdf  \n3. List the subparts or phases of analysis part.  \nAnalysis consists of three phases:  \n Linear Analysis.  \n Hierarchical Analysis.  \n Semantic Analysis.  \n4.

What is linear analysis?  \nLinear analysis is one in which the stream of characters making up the source program is read from left to right and grouped into tokens that are sequences of characters having a collective meaning.  \nAlso called lexical analysis or scanning.  \nCOMPILER DESIGN Questions  \n6. List the various phases of a compiler.  \nThe following are the various phases of a compiler:  \n1. Lexical Analyzer  \n2. Syntax Analyzer  \n3. Semantic Analyzer  \n4. Intermediate code generator  \n5. Code optimizer  \n6. Code generator  \n7. What are the classifications of a compiler?  \nCompilers are classified as:  \n Single-pass  \n Multi-pass  \n Load-and-go  \n[http://engineeringinterviewquestions.com/compiler-design-questions-answers/ 3/20](http://engineeringinterviewquestions.com/compiler-design-questions-answers/ 3/20)  \n3/19/2019 100 TOP COMPILER DESIGN Important Questions and Answers Pdf  \nDebugging or optimizing  \n8. What is a symbol table?  \nA symbol table is a data structure containing a record for each identifier, with fields for the attributes of the identifier. The data structure allows us to find the record for each identifier quickly and to store or retrieve data from that record quickly.  \nWhenever an identifier is detected by a lexical analyzer, it is entered into the symbol table. The attributes of an identifier cannot be determined by the lexical analyzer.  \n9. Mention some of the cousins of a compiler.  \nCousins ofthe compiler are:  \n Preprocessors  \n Assemblers  \n Loaders and Link-Editors  \n10. List the phases that constitute the front end of a compiler.  \nThe front end consists of those phases or parts of phases that depend primarily on the source language and are largely independent of the target machine.
