CSCE 3600 EXAM QUESTIONS AND ANSWERS
LATEST UPDATE (ALREADY GRADED A+)
What is the function of a linker? (general)
Combines previous compiled and assembled object code along with standard library functions to make
an executable file
What does a linker do with external references in object files? (input/output)
Resolves references in each object file to external variables and procedures declared in other files
What is the role of loaders in programming? (Loaders)
Loaders ensure that object programs are placed in memory in an executable form.
What task does a loader perform regarding memory addresses? (Loaders)
A loader calculates appropriate absolute addresses for memory locations and amends the code to use
these addresses.
Compilers general
Consists of a piece of system software that translates high-level languages into machine language
What is the role of compilers?
Compilers provide an essential interface between applications and architectures.
How do high-level programming languages benefit programmers?
High-level programming languages increase programmer productivity, improve maintenance, and
enhance portability.
What low-level machine details do compilers handle?
Compilers handle instruction selection, addressing modes, pipelines, registers, and cache.
How do compilers shield application developers?
Compilers efficiently bridge the gap and shield application developers from low-level machine details.
What are the requirements for a compiler to generate a correct executable?
The input program and the output program must be equivalent, the compiler should preserve the
meaning of the input program.
What is the expectation for the speed of the output program generated by optimizing compilers?
The output program should be more efficient than the input program.
, What are some characteristics of a fast compiler?
The compiler itself should be fast and the compile time should be proportional to code size.
What are some requirements for a compiler to provide good diagnostics for programming errors?
The compiler should support separate compilation and work well with debuggers.
What should be consistent and predictable in compiler optimizations?
Optimizations should be consistent and predictable.
What is the main function of a syntax analyzer?
To analyze the syntactical structure of a given input according to a defined grammar and produce a
parse tree or syntax tree.
What is tokenization in the context of a syntax analyzer?
Tokenization involves breaking down the input stream into tokens, which are the smallest units of the
language syntax.
What is the role of error handling in a syntax analyzer?
Error handling involves detecting and reporting syntax errors if the input doesn't conform to the
grammar rules.
How does a syntax analyzer use a parse tree?
A syntax analyzer builds a parse tree that represents the syntactical structure of the input, which can be
used for further processing by the compiler or interpreter.
What is the input of a syntax analyzer?
The parser takes a sequence of tokens, typically generated by the lexer (lexical analyzer), as its input.
What is a parse tree in the context of syntax analysis?
A parse tree is a graphical representation of the syntactical structure of the input according to the
grammar rules, used for understanding and validating the structure of the input.
What is a context-free grammar (CFG) used for?
A context-free grammar is a formalism used to define the syntax of a programming language, consisting
of production rules that describe how different syntactical constructs can be formed.
What is the purpose of profilers in software development?
Profiling helps identify resource-consuming areas for performance optimization, bottleneck detection,
resource analysis, and code coverage.
What is the difference between instrumentation and sampling profilers?
Instrumentation profilers modify code to measure specific points precisely, while sampling profilers
periodically interrupt programs to approximate function execution.
