AND CORRECT ANSWERS GRADED

◉ Benchmarking.
Answer: Running a program on many data sets to be sure its
performance falls within required limits; timing the same algorithm on
two different machines.
◉ Code library.
Answer: A collection of thoroughly tested object code for various useful
tasks.
◉ Coding.
Answer: The process of translating the detailed designs into computer
code.
◉ Divide-and-conquer.
Answer: A program design strategy in which tasks are broken down into
subtasks, which are broken down into sub-subtasks, and so on, until each
piece is small enough to code comfortably. These pieces work together
to accomplish the total job.
,◉ Empirical testing.
Answer: Designing a special set of test cases and running the program
using these test data.
◉ Executable module.
Answer: The resulting object code after a linker inserts requested code
from code libraries.
◉ External documentation.
Answer: Any materials assembled to clarify the program's design and
implementation.
◉ Feasibility study.
Answer: A step in the software development life cycle that evaluates a
proposed project and compares the costs and benefits of various
solutions.
◉ Integrated development environment (IDE).
Answer: A collection of programs that support software development,
such as debuggers, editors, toolkits, and libraries, that lets programmers
perform several tasks within the shell of a single application.
◉ Integration testing.
Answer: After unit testing, integration testing is done to see that the
modules communicate the necessary data between and among
themselves and that all modules work together smoothly.
,◉ Internal documentation.
Answer: Documentation that is part of the program code itself.
◉ Logic error.
Answer: An error in the algorithm used to solve a problem.
◉ Object code.
Answer: Machine language instructions.
◉ Pair programming.
Answer: Involves two programmers at a single workstation. At any
given point in time, one is writing code and the other is actively
observing, watching for possible errors
but also thinking about the overall approach.
◉ Problem specification.
Answer: A step in the software development life cycle that involves
developing a clear, concise, and unambiguous statement of the exact
problem the software
is to solve.
◉ Procedural language.
, Answer: A program written in a procedural language consists of
sequences of statements that manipulate data items.
◉ Program design phase.
Answer: A step in the software development life cycle that plans the
structure of the software to be written.
◉ Program maintenance.
Answer: The process of adapting an existing software product due to
errors, new system requirements, or changing user needs.
◉ Program verification.
Answer: Used to prove that if the input data to a program satisfies
certain conditions, then, after the program has been run on these data,
the output data satisfies certain other conditions.
◉ Regression testing.
Answer: If anything is changed on an already-tested module, regression
testing is done to be sure that this change has not introduced a new error
into code that was previously correct.
◉ Runtime error.
Answer: An error that occurs when the program is run using certain sets
of data that result in some illegal operation, such as dividing by zero.
