specific language.
C) writing the code for a program.
D) writing the documentation for a program. - ANSWER B) steps a programmer
should do before they start coding a program in a specific language.
Software testing involves the execution of a software component or system
component to evaluate one or more properties of interest.
True or False - ANSWER true
Programming starts with:
a) looking online for the answers.
b) writing code until it works.
c) developing an algorithm. - ANSWER c) developing an algorithm.
Input is sending messages to the console/user.
true or false - ANSWER false
input is actually: - ANSWER reading and taking in information from the user
Output is process of reading information from user, usually via keyboard or
mouse.
true or false - ANSWER false
output is actually: - ANSWER messages/ what is being displayed to the user
based off of the input information
A flowchart is a type of diagram that represents an algorithm, workflow or
process.
true or false - ANSWER true
,Pseudocode is
A) a formal programming language.
B) a machine.
C) an informal high-level description of the operating principle of a computer
program or algorithm. - ANSWER C) an informal high-level description of the
operating principle of a computer program or algorithm.
Debugging is the process of
a) compiling the source code.
b) publishing the source code to the client.
c) writing source code.
d) solving errors in the source code. - ANSWER d) solving errors in the source
code.
The MAIN method tells the program where to begin running code as it is the
entry or starting point for the program.
true or false - ANSWER true
IDE stands for
a) Initial Degree Expectations
b) Integrated Development Environment
c) Intramural Department Executive - ANSWER b) Integrated Development
Environment
What is the output of the following code?
BEGIN MAIN
int u = 3;
int v = 5;
u += v;
v += u;
u -= v;
v -= u;
PRINT (u + ", " + v);
END MAIN
a) 5, 3
b) -5,-3
c) 3, 5
d) -5, 18 - ANSWER d) -5, 18
EXPLANATION
, 3 += 5 = 8(u) (3 + 5)
5 += 8 = 13(v) (5 + 8)
8 -= 13 = -5(u) (8 - 13)
13 -= -5 = 18(v) (13 - (-5))
so = -5, 18 is the final outcome
What would be the best datatype to represent product? A variable that stores
information about the number of items currently in stock in a grocery store.
a) double
b) int
c) float
d) String - ANSWER b) int
(number of items in the store is going to be a whole number)
What is the value of j after this code is executed?
BEGIN MAIN
int i = 6, int j=10;
j+=i;
END MAIN
a) 10
b) 6
c) 4
d) 16 - ANSWER d) 16
A String (or string) object is a primitive data type.
true or false - ANSWER false
a string is actually: - ANSWER - composite of other data types
- Strings are immutable which means once a String object is created its contents
cannot be changed. (cant change in memory)
- complex: can be broken down into characters
What is the output of the following code?
BEGIN MAIN
int num1 = 500;
int num2 = 200;
int num3 = 300;
double average = num1 + num2 + num;
PRINTLINE(average);
END MAIN
