• What is a program or software program?


  A set of instructions that tells the computer hardware to perform a task.
• Who usually writes computer programs?

  A programmer.
• What is an algorithm?


  A set of mathematical instructions or rules that solves a problem.
• How can an algorithm be described?


  As a step-by-step procedure that solves a problem.
• What does the term 'paradigm' refer to in programming?


  A way of looking at control flow and execution of a program.
• What is declarative programming?


  Programs describe their desired results without explicitly listing commands or steps.
• What is imperative programming focused on?


  Describing how a program operates.
• How is object-oriented programming defined?


  Programs are defined by objects which combine state and behavior.
• What are conditional structures in programming?


  Structures that perform actions based on a true or false decision.
• What do looping structures do?


  They execute a list of instructions more than once.
• What is pseudocode?


  An outline of a program written in a way that can be converted to programming statements.
• Why is pseudocode also called a "text-based" detail design tool?


  Because the program is written rather than drawn.
• What does syntax refer to in programming?


  The acceptable format of a programming statement.
• What are keywords in pseudocode?


  Reserved words with special functions used in pseudocode.
• What is the purpose of comments in programming?


  To explain a certain statement, function, or the purpose of a program.
• What are data types in programming?


  Formats in which data can be stored, classifying a particular type of information.
• What are the main programming paradigms discussed?

  • Declarative programming
  • Imperative programming
  • Object-oriented programming
• What are real numbers?


  Real numbers are numbers that have a whole number and a fractional part.
• What type of data do real numbers contain?


  Real numbers contain decimal numbers.
• What do integers store?


  store whole numbers.
• Can integers be positive or negative?


  Yes, integers can be both positive and negative.
• What do strings hold?


  Strings can hold alphanumeric characters including text, numbers, and symbols.
• What does a character hold?


  A character holds a single character only.
• What is the purpose of a boolean data type?


  Boolean is used to answer questions where there are exactly two options.
• What is a variable?


  A variable is a storage location paired with an associated symbolic name that contains some known and unknown quantity of information referred to as a value.
• How does the value of a variable change?


  The value of a variable can change depending on conditions or information passed to the program.
• What should the name of a variable be?


  The name of a variable should be symbolic, representing the title of the information being stored.
• What does the type of a variable represent?


  The type represents what kind of data is stored with the variable.
• What is the scope of a variable?

  The scope refers to the sections of a program where a variable is accessible.
• What does "stored" refer to in the context of variables?


  "Stored" refers to the last piece of information assigned to the variable name.
• What does a terminator indicate in a program flow diagram?


  A terminator indicates the beginning or end of a program flow in your diagram.
• What does a process symbol indicate in a flowchart?


  A process symbol indicates any processing function.
• What does a decision symbol represent in a flowchart?


  A decision symbol indicates a decision point between two or more paths in a flowchart.
• What does an Input/Output symbol represent in a system?


  An Input/Output symbol represents material or information entering or leaving the system.
• What does a preparation symbol represent in a process?

  A preparation symbol represents a set-up to another step in the process.
• What does a terminal symbol represent?


  A terminal symbol is used to represent Begin/End or Start/Finish in a flowchart.
• What are operators in programming?


  Operators are symbols that tell how to perform specific mathematical or logical operations.
• What are relational operators used for?


  Relational operators are used for comparison and return either true or false based on the comparison result.
• Value – by its very name, it changes over time.
• Scope – good programs are chopped into a small, contained sections named functions.
