www.ramkumarsjava.comSource program to object or target program

www.ramkumarsjava.comQ2>The time of conversion from source program into object program is called ________time.a)runtimeb)boot timec)fresh timed)compile time

www.ramkumarsjava.comcompile time

www.ramkumarsjava.comQ3>The program execution is done in compiler in_________________.

www.ramkumarsjava.comTokens or terminals

www.ramkumarsjava.comQ8>Syntax Analyzer is otherwise known as _____________.a)Scannerb)Parserc)Lexemed) Sub scripter


www.ramkumarsjava.comQ9>What are the work of a semantic analyzer?

www.ramkumarsjava.coma)Type Checkingb)Type Conversions

www.ramkumarsjava.comQ10>The synthesis phase is the ____________of a program.

www.ramkumarsjava.comBack endwww.ramkumarsjava.comQ11>What are the stages of synthesis of target program?

www.ramkumarsjava.comMemory allocationCode generation and optimization

www.ramkumarsjava.comQ12>Code optimization is done for-

www.ramkumarsjava.comfaster and shorter code

www.ramkumarsjava.comQ13>_____________ is a data structure that is used by the compiler to hold the information about source program constructs.

www.ramkumarsjava.comSymbol tablewww.ramkumarsjava.comQ14>What are the role of a compiler? Analyzer-Syntactic Analyzer-Semantic Analyzer-Code generator-Code optimizer-Error reporter

www.ramkumarsjava.comQ17>Code generation and optimization is not a part of synthesis phasea)Trueb)False Q18>The first compiler was written by _____________ in ________for A-0 system languagewww.ramkumarsjava.comGrace Hopper,1952www.ramkumarsjava.comQ19>Who invented first complete compiler?

www.ramkumarsjava.comThe FORTRAN team led by John W.Backus at IBM in 1957

www.ramkumarsjava.comQ20>___________ was one of the early commercial computers that used vacuum tubes. Z22

www.ramkumarsjava.comQ21>The first known demonstrated cross platform high level language was_____________.a)FORTRANb)COBOLc)BASICd)ALGOL

www.ramkumarsjava.comCOBOLwww.ramkumarsjava.comQ22>A compiler that can be written in the programming language it compiles-

www.ramkumarsjava.comSelf hosted

www.ramkumarsjava.comQ23>The first self hosting compiler was written for LISP by_______________and ______________ in 1962.

www.ramkumarsjava.comTim Hart and Mike Levinwww.ramkumarsjava.comQ24>Structure of a compiler depends on 3 factors. What are they?

www.ramkumarsjava.comNature of the source languageMachine architecture and configurationAims of compiler

www.ramkumarsjava.comQ25>Different types of compiler structure are-

www.ramkumarsjava.comSingle pass compilerMultipass compilerConventional compilerCompilers for permissive languageIncremental compiler

www.ramkumarsjava.comQ26>Strike the one out which doesnt match for single pass compilers.-All the stages executed in single flow-Memory requirement is small-Code generated is inefficient-Faster execution

www.ramkumarsjava.commemory requirement is small

www.ramkumarsjava.comQ27>Pascal and FORTRAN are example of ______________compiler.

www.ramkumarsjava.comsingle pass

www.ramkumarsjava.comQ28>____________is an example of multipass compiler.
