RANDOM
This is a definition of the acronym "IDE", and its key functions in software development.
What is an "Integrated Development Environment", that provides tools for coding, debugging, and compiling software?
These are the most common symbols you will find in flowchart design. This is also an explanation of the symbols' purposes.
What are answers like the below that are fact checked by the cohort?

This is the concept of hiding all but the relevant data and interface processes for an object in order to reduce complexity and increase efficiency.
What is abstraction?
These are special array-based data structures with special access control processes. (Let’s you control order of processing data).
One is Last in First Out (LIFO), and the other is First in First Out (FIFO).
What are stacks and queues, respectively?
This is the decimal number 35 converted to binary.
What is 100011?
These are the three main categories of error types you can encounter when debugging code.
(Bonus for 150 pts: This is one example for each error type of a tool or strategy you can use to debug the program)
What are syntax, logic, and runtime errors?
Bonus: What are 3 answers fact-checked by the cohort?
Note: Use error messages, reference materials, language documentation, and debugging tools to identify and fix syntax, runtime, and logic errors.
This is a list of the boolean logic operators, stated in their order of precedence.
What is NOT, AND, and OR?
This concept allows several variations of a method with the same name, but with different parameter signatures, to allow for flexibility.
These are three operations defined for processing the stack and the queue.
What are the following operations?
push - add something
pop - remove something
peek - look at what would be popped but don’t pop
This is 1010101 written in decimal.
What is 85?
This is the difference between a data type and a data structure. (When answering, please also provide examples)
What is a data type, which defines the kind of data (e.g., integer, string, boolean, char)?
What is a data structure that organizes data (e.g., array, list, stacks, queues)?
This is the difference between a series of if statements and a series of else if statements.
What is an answer similar to the following?
When provided a series of if statements, your program will evaluate each individual if statements for a true or false result, regardless of the previous if statements result.
With a series of if/else if statements, the else if statements will ONLY run if the previous statement was evaluated FALSE. Otherwise, it will check each statement until it finds a TRUE result.
A "Vehicle" class might have properties like "number of wheels" and "maximum speed." A "Car" class, inheriting from "Vehicle," could add properties like "number of doors" and "sunroof." This concept demonstrates how sub-classes can extend and specialize the functionality of their parent classes.
What is inheritance?
Consider the following pseudocode fragment, where Q is a Queue instance that will hold integers:
Queue Q ← new Queue()
Q.enqueue(10)
Q.enqueue(20)
Q.enqueue(30)
Q.dequeue()
Q.enqueue(40)
Q.enqueue(Q.dequeue() + Q.peek())
Q.dequeue()
print(Q.dequeue())
This is printed by the last line of code.
What is 40?
This is 011101 written in hexadecimal.
What is 1D?
This is a description of the "black box" approach in program design and its benefits.
What is designing a component so that its internal workings are hidden? What is ensuring users only interact with its inputs and outputs, simplifying the program's use?
This is the output of the following code segment:
int num1 ← 30
int num2 ← 15
int num3 ← num1 % num2
int num4 ← num2 % num1
if(num3 < num4)
print num3
else
print num4
end if
What is 0?
This is an example of the difference between composition (the process of designing a class that is composed, in part, of other predefined classes) and inheritance.
This is an explanation of an "is-a" vs. "has-a" relationship.
What is composition is a "has-a" relationship, and inheritance is an "is-a" relationship?

Consider the following pseudocode fragment, where Q is a Queue instance that will hold integers.
Queue Q ← new Queue ()
Q.enqueue (5)
Q.enqueue (12)
Q.enqueue (4)
Q.dequeue ()
Q.enqueue (13)
Q.enqueue ( Q.peek () - Q.peek() )
Q.enqueue ( Q.dequeue () + Q.dequeue () )
Q.dequeue ()
print (Q.dequeue () )
This is what is printed by the last line of code.
What is 0?
This is the octal value of 77 written in decimal.
What is 63?
This distinguishes low-level languages from high-level languages?
What are low-level languages (like assembly), which are closer to machine code? What are high-level languages (like Python, Java), which are more human-readable?
This is the result of the following code segment:
int x ← 5
int y ← 10
if(x >= 5 )
if(y != 10)
print "option A"
else
print "option B"
end if
else
if(y < 11)
print "option C"
else
print "option D"
end if
end if
What is option B?
This concept involves combining data and the methods that operate on it into one unit, usually a class. It protects data from accidental modification, enhances code organization, and streamlines interaction between program components.
What is encapsulation?
Consider the following pseudocode fragment, where P is a Stack instance that will hold integers.
P.push(7)
P.push(5)
P.push(P.peek() * P.pop())
P.push(P.pop() + P.peek())
P.pop()
This is the value on top of the stack after these operations.
What is 7?
What is octal 467 in hexadecimal?
What is 137?
