Terms in this Study Set(36)
Programming Concepts(16)
Algorithm → Definition
A step-by-step procedure for solving a problem or performing a task.
True or False: Algorithms can be represented in multiple forms.
True. Algorithms can be expressed in natural language, pseudocode, or flowcharts.
Fill in the blank: An abstract representation of a real-world problem is called ____.
Abstraction.
Compare: Array vs. List
Array: Fixed size, faster access. List: Dynamic size, more flexible.
What is abstraction in programming?
The process of simplifying complex systems by hiding unnecessary details.
Cause → Effect: Using data structures
Cause: Choose efficient data structure. Effect: Improved performance and memory usage.
What is a data structure?
A way to organize and store data for efficient access and modification.
True or False: A stack follows LIFO principle.
True. Last In, First Out ensures the last added element is the first to be removed.
Example of an algorithm: Sorting a list
1. Start 2. Compare elements 3. Swap if necessary 4. Repeat until sorted.
What does the term 'iteration' refer to?
The repetition of a process in programming, often with loops.
Define 'conditional statements'.
Statements that execute different code blocks based on boolean expressions (if, else).
Comparison: Array vs. Dictionary
Array: Indexed by integers. Dictionary: Key-value pairs for fast lookups.
True or False: Abstraction increases code complexity.
False. Abstraction simplifies complex systems by hiding details.
What is a variable?
A named storage location in memory that can hold different values.
Fill in the blank: A loop that runs indefinitely is called a ____ loop.
Infinite.
What is a function?
A block of reusable code that performs a specific task and may return a value.
Performance Task Requirements(12)
What is the purpose of the Create Performance Task?
To assess students' ability to develop a computer program and document their process.
True or False: The Create Performance Task requires a team effort.
False. It is an individual task where each student creates their own program.
Fill in the blank: The program must include ____ algorithms.
at least two algorithms, each demonstrating different problem-solving approaches.
What does the program's documentation need to include?
A written response detailing the programming process, algorithms used, and the purpose of the program.
Comparison: Program development vs Documentation.
Program development involves coding; documentation involves explanation and justification of choices made.
List the two main components of the Create Performance Task.
1. Program Code 2. Written Response
How many lines of code are required in the program?
A minimum of 20 lines of code must be included in the final submission.
What is the role of the written response?
To explain the program's purpose, algorithms, and functionality in a clear manner.
True or False: A program can be submitted without a written response.
False. The written response is essential for providing context and understanding the program.
Cause → Effect: Effective documentation leads to _____.
clearer understanding and appreciation of the program by evaluators.
What programming languages are acceptable for the task?
Any programming language that can be understood and clearly documented.
What must be included in the final program submission?
The program code, screenshots of the program in action, and the written response.
Debugging and Testing(8)
What is debugging?
The process of identifying and removing errors from computer code. - Syntax errors - Runtime errors - Logic errors
True or false: Debugging is only necessary after code is complete.
False. Debugging should occur continuously during development to catch issues early.
Fill in the blank: A _____ is a common technique to help find logical errors.
trace or debug statement
Comparison: Testing vs. Debugging
Testing evaluates if code meets requirements. Debugging fixes issues found during testing.
What is a unit test?
A test that verifies the functionality of a specific section of code. - Often automated - Focuses on small parts
Cause → Effect: Code fails to run.
Cause: Syntax error. Effect: The program does not execute as intended.
How do you identify a logic error?
By running the code with test cases and checking if outputs are as expected.
Example of using print statements:
Insert print statements before and after critical operations to track variable changes.
