ICT Q2 EXAM

• What are variables used for in C++?

  To store data for later use
• What are the main data types in C++?

  • String (sentences)
  • Char (one letter)
  • Bool (true or false)
  • Int (positive & negative numbers)
  • Float (less precise decimal)
  • Double (more precise decimal)
• What does the char data type represent in C++?

  It represents a single letter
• What does the bool data type indicate in C++?

  It indicates true or false values
• What is an example of an int variable in C++?

  numberOne = 100
• How does the float data type differ from the double data type in C++?

  Float is less precise than double
• How would you print "B1 is a programmer" in C++?

  Cout << "B1 is a programmer" << endl;
• What is the output of the following C++ code?

  Cout << nameOne << " is a" << occupation << endl;

  • Outputs: "B1 is a programmer"
• What does the endl command do in C++?

  It ends the current line and moves to the next line
• What is the purpose of the variable occupation in the provided C++ code?

  To store the string "programmers"
• How would you declare two string variables in C++?

  • String nameOne = "B1";
  • String nameTwo = "B2";
• What is the output of the following C++ code?

  Cout << nameOne << " and" << nameTwo << " are partners" << endl;

  It outputs: "B1 and B2 are partners"
• Who prepared the pseudocode document?

  JOHN MICHAEL E. LANDAS
• What is pseudocode?

  A method that allows a programmer to represent the algorithm in a programming-related way
• Why is pseudocode also called false codes?

  Because it tends to look like a programming language but can still be understood by non-programmers
• What are the do's and don'ts of writing pseudocode?

  Do's:

  • Proper naming convention
  • Simple and concise

  
  

  Don'ts:

  • Don't make it abstract
  • Don't make it generalized
• What is the pseudocode for a program that displays the sum of two numbers?

  Let numOne = 0, numTwo = 0 and sum = 0; Input numOne and numTwo; sum = numOne + numTwo; Output sum
• What is the pseudocode for a program that displays the average of two numbers?

  Let numOne = 0, numTwo = 0, sum = 0 and ave = 0; Input numOne and numTwo; sum = numOne + numTwo; ave = sum/2; Output ave
• What is an alternative pseudocode for calculating the average of two numbers?

  Let numOne = 0, numTwo = 0 and ave = 0; Input numOne and numTwo; ave = (numOne + numTwo)/2; Output ave
• What is the programming problem for displaying "Even" or "Odd"?

  Create a program that will display "Even" or "Odd" depending on the number inputted by the user
• Who prepared the flow chart?

  John Michael E. Landas
• What is the purpose of pseudocode in programming?

  • To represent algorithms in a programming-related way
  • To be understandable by individuals with little programming knowledge
  • To serve as a bridge between human language and programming languages
• What is a flow chart?

  A method that allows a programmer to represent an algorithm in a diagram or illustration
• What is the best website for creating flow charts?

  draw.io
• What does a flow chart represent in programming?

  It represents the sequence of a programming algorithm using standard graphic symbols
• What is the pseudocode for a program that displays the sum of two numbers?

  1. Let numOne = 0, numTwo = 0, and sum = 0
  2. Input numOne and numTwo
  3. sum = numOne + numTwo
  4. Output sum
• What is the pseudocode for a program that determines if a number is even or odd?

  1. Let num = 0
  2. Input num
  3. If num is an even number, Output "Even"
  4. If num is an odd number, Output "Odd"
• Who prepared the content on common types of program algorithms?

  John Michael E. Landas
• What does the learner demonstrate in the content standards?

  Understanding of algorithms and programming
• What is the performance standard for learners regarding algorithms and programming?

  Independently demonstrate knowledge and skills in developing a computer program
• What are the objectives of the study material?

  • Discuss Sequential and Conditional selection
  • Write codes using variables
• What questions were posed regarding the relevance of program algorithms?

  Why study program algorithm? Can we apply it in our daily living?
• What are the common types of program algorithms mentioned?

  • Sequential
  • Conditional
  • Looping/Repetition
  • Modulo
• What is a sequential algorithm?

  An algorithm that runs from top-down without interruption until it finishes
• What is a problem example for a sequential algorithm?

  Create a pseudocode and flowchart for computing an employee's salary
• What is the pseudocode for computing an employee's salary?

  • Let rate = 0; hours = 0; salary = 0;
  • INPUT rate, hours
  • Salary = rate * hours
  • OUTPUT salary
• What is the formula to compute salary in the pseudocode?

  Salary = rate * hours
• What is a problem example for a conditional algorithm?

  Create a pseudocode and flowchart for computing an employee's salary with conditions
• What does a conditional algorithm do?

  Affects the output based on a certain condition
• What is the pseudocode for the conditional salary computation?

  • Let salary = 0; rate = 0; hours = 0;
  • INPUT rate, hours
  • Salary = rate * hours
  • IF salary > 10000 THEN
  • OUTPUT "High Pay"
  • ELSE
  • OUTPUT "Low Pay"
  • ENDIF
