Interpreter
Assembler
Linker
Which of the following is a feature of high-level languages?
They are machine-dependent.
They are difficult for humans to understand.
They are close to human language.
They consist of zeroes and ones.
What is the difference between a compiler and an interpreter?
A compiler translates the program line by line, while an interpreter converts instructions into 0s and 1s.
An interpreter converts the instructions into 0s and 1s, while a compiler translates the program line by line.
Compilers convert instructions into 0s and 1s, and interpreters translate the program line by line as it is running.
There is no difference; they are the same thing.
What are the three basic control structures used in programming?
Analyze, Plan, Desk-check
Input, Processing, Output
Sequence, Repetition, Selection
Logic, Syntax, Debugging
What does the repetition structure direct the computer to do?
Process instructions in the order they are listed.
Make a decision and take action based on that decision.
Repeat one or more instructions until a condition is met.
Transform input into output.
The selection structure is also known as what?
Loop
Iteration
Sequence
Decision structure
What is pseudocode?
A diagram using shapes and arrows to represent process flow.
A set of step-by-step instructions that can be understood by a computer.
A planning tool using English-like statements to describe an algorithm.
The final source code of a program.
What is the purpose of a flowchart?
To write the actual program code.
To provide a step-by-step guide for humans.
To serve as a planning tool that uses diagrams to represent the process-flow of a program.
To compile a program.
What is the first step in creating a computer solution to a problem?
Planning the algorithm.
Coding the algorithm.
Analyzing the problem.
Desk-checking the algorithm.
What is the purpose of an IPO chart?
To analyze a problem by organizing and summarizing the input, processing, and output.
To write the actual program code.
To draw a flowchart.
To test the program with invalid data.
What does "IPO" stand for in the context of problem-solving?
Internal, Process, Operation
Input, Program, Output
Input, Processing, Output
Instructions, Program, Operators
An algorithm is defined as:
A program written in a programming language.
A diagram representing a process flow.
A set of instructions that transforms a problem's input into its output.
The process of finding errors in a program.
Why is pseudocode also called "false code"?
Because it uses symbols and arrows.
Because it is written in English-like statements.
Because it resembles programming language instructions but cannot be understood by a computer.
Because it is always incorrect.

Rectangle
Parallelogram
Diamond
What is the purpose of desk-checking an algorithm?
To translate the algorithm into machine language.
To follow each of the algorithm's instructions by hand using a pencil and paper.
To fix syntax errors in the program.
To evaluate and modify the program after it has been coded.
A programmer testing an algorithm with data they do not expect the user to enter is using:
Valid data
Invalid data
IPO data
Random data
What is the next step after analyzing a problem and planning the algorithm?
Coding the algorithm into a program.
Desk-checking the algorithm.
Desk-checking the program.
Evaluating and modifying the program.
What is the purpose of internal memory in a computer?
To display messages on the computer screen.
To hold the program's source code.
To store the values of input, processing, and output items as a program runs.
To translate source code into machine code.
A memory location whose value can change during runtime is called a(n):
Keyword
