d278 Final Review set
1. Variable type that holds person height or measure in length: Float
2. Constant Vs Variable: Constant- value won't change ex 60 seconds in a minute. Variable- Value
can change
3. ==: Equality or comparison
4. Which expression represents all the values of x when x is the age ranging from 18 to 24 years
old.: (x>= 18) and (x<= 24)
5. what is the loop expression in the following code i = o
while i < 20 Put i to
output i = i + 1: i <
20
6. what is the variable initialization in the following code i = o
while i < 20 Put i to
output i = i + 1: i =
o
7. Which phase of a waterfall approach would create a sequence diagram that specifies the required
order of events between completed program compo- nents?: Design
8. Which phase of an agile approach would define a hypothesis to find a problem in a
program?: Testing
9. Which phase of an agile approach would create an executable program?: -
Implementation
10.Which phase of an agile approach would create a list of components needed to build an
online auction site?: Design
11.Which phase of a waterfall approach defines a program's goals?: Analysis
12.After a programmer is done writing a program, another person runs the program hundreds of
times, each time with different input, checking that each run yields correct output. Which phase of a
waterfall approach is the person carrying out?: Testing
13.A programmer decides a program should convert U.S. units to metric units and decides to write
the program in C++ using several functions. Which phase of a waterfall approach is occurring when
the programmer starts writing the program?: Implementation
14.A company has a new project it wishes to implement to track and analyze employee and
customer interactions. The company leadership determines that the system should support direct
data entry as well as automated data capture of phone calls and emails. Which phase of the waterfall
process is occurring?: Analysis

15.A programmer shows a program's first version to a customer. The cus- tomer provides feedback,
which causes the programmer to change the goals of the program.In which phase of an agile
approach are goals changed based on customer feedback?: Analysis
16.A programmer shows a program's first version to a customer. Based on feedback, the
programmer begins writing a second version of the program. In which phase of an agile approach
does the writing of a second version of the program occu: Implementation
17.A programmer shows a program's first version to a customer. Based on feedback, the
programmer creates a second version, and then has a colleague run the second version on numerous
inputs to ensure outputs are correct. Which phase of an agile approach is that colleague carrying
out?: Testing
18.A programmer is currently programming the fourth version of a program. Each version has
additional features to satisfy more customers.In which phase of an agile approach does the
programming of the fourth version occur?: Implementation
19.What is the purpose of a class diagram: Depicts the Employee class' name, data members,
and functions
20.Purpose of a case diagram: Describes how a user can interact with a program
21.Elements are characteristics of a class diagram: System's classes, attribut- es, and methods
and their features, constraints, and relationships
22.structural diagram: visualizes static elements of software, such as the types of variables and
functions used in the program
23.behavioral diagram: visualizes dynamic behavior of software, such as the flow of an
algorithm. for example activity diagram is one.
24.activity diagram: An activity diagram is like a flowchart, describing at a high-lev- el the
sequence of computations.
Behavior diagram
Happens at Implementation phase
25.use case diagram: shows various things a user might do. A user might enter data,
compute an absolute value, or compute a mean.
behavioral diagram Happens at
analysis phase
26.Class diagram: shows a program's parts (classes). A DataSet class might compute
statistics on data. A DataVisualizer does that plus draws bar charts and histograms.
structural diagram Happens
at Design phase
