2.1.1 Problem-solving and programming

• What are the five steps in the problem-solving process?

  Understand, plan, implement, test, evaluate
• Match the data type with its example:

  Integer ↔️ 1

  Float ↔️ 3.14

  String ↔️ "Hello"

  Boolean ↔️ true
• Declaring variables with appropriate data types improves program organization and performance.


  True
• Match the flowchart shape with its meaning:

  Process ↔️ Action to be performed

  Decision ↔️ Branching point

  Input/Output ↔️ Data entry or output
• An input/output in a flowchart is represented by a parallelogram
• Flowcharts use standardized shapes to depict different elements of an algorithm.


  True
• Match the data type with its description:

  Integer ↔️ Whole numbers

  Float ↔️ Numbers with decimal points

  String ↔️ Text in quotation marks

  Boolean ↔️ True or false values
• What is the first step in developing an algorithm?

  Define the problem
• Flowcharts are visual diagrams that use shapes to represent processes and data flow.


  True
• What is pseudocode used for in algorithm design?

  Describe algorithm steps
• Planning a solution involves devising a step-by-step strategy.


  True
• The problem-solving process helps break down complex problems into manageable steps.


  True
• Why is it important to choose the correct data type for a variable?

  Efficient memory usage
• What does a rectangle symbol represent in a flowchart?

  A process
• Programming syntax refers to the rules for structuring statements in a language
• Operators in programming syntax perform arithmetic, logical, and comparison operations.


  True
• Text enclosed in quotation marks in programming is a string
• Control structures manage the flow of program execution


  True
• Data types define the kind of values variables can hold


  True
• Control structures include loops and conditional statements


  True
• Data types define the kind of values variables can hold
• Steps to learn basic programming syntax

  1️⃣ Define variables

  2️⃣ Specify data types

  3️⃣ Use operators

  4️⃣ Employ control structures
• Match the data type with its description and example:

  Integer ↔️ Whole numbers | 1, -10

  Float ↔️ Numbers with decimal points | 3.14, -0.5

  String ↔️ Text in quotation marks | "Hello", "World!"

  Boolean ↔️ Logical true or false | true, false
• Data types define the kind of values variables can hold
• Control structures manage the flow of program execution
• Operators perform arithmetic, logical, and comparison operations

  True
• Pseudocode is a simple English-like notation for describing algorithms


  True
• The pseudocode to calculate the sum of numbers in a list initializes the sum to zero
• Flowcharts use visual diagrams to represent processes, decisions, and data flow
• The problem-solving process involves continuous evaluation and refinement of the solution.


  True
• The boolean data type stores values that are either true or false.
• In a flowchart, a rectangle represents a process or action to be performed.
• A diamond in a flowchart represents a branching point based on a condition.

  True
• Steps in a simple flowchart to determine if a number is even or odd

  1️⃣ Start

  2️⃣ Get Number

  3️⃣ Is Number Even?

  4️⃣ Yes or No Branch

  5️⃣ End
• What defines the kind of values variables can hold?

  Data types
• Control structures in programming syntax control the flow of execution
• What is a simple English-like notation used to describe the steps of an algorithm?

  Pseudocode
• Testing an algorithm involves verifying that the solution produces correct results.

  True
• The first step in the problem-solving process is to understand the problem
• What should you do after testing a solution in the problem-solving process?

  Evaluate and refine
