Programming Instruction Sequences Quiz

Questions and Answers

Match the following programming concepts with their descriptions:

Repeat Until Loop = Executes a set of instructions until a specific condition is met If Statement = Allows for decision-making based on a condition If-Else Statement = Provides an alternative path of execution when a condition is not met Move Forward Block = Instructs an object to move in a specified direction

Match the following scenarios with the correct programming action:

Bird reaching the pig = Using a 'repeat until' block to move forward until reaching the pig Checking for path to the left = Implementing an 'if' statement to determine if there's a path to the left Moving forward or turning left = Utilizing an 'if-else' statement to handle different paths Wearing a jacket based on rain = Analogous use of an 'if' statement in daily decision-making

Match the following terms with their definitions:

General-purpose programming = Programming languages designed for various applications Client-side scripting for web applications = Code that runs in a user's web browser Database queries = Commands used to interact with databases Styling web pages = Defining the look and layout of web content

Match the block of instructions with their corresponding action:

<ol> <li>Move Forward one space = moveForward();</li> <li>Turn left or right by 90 degrees = turnRight();</li> <li>Do some statements several times = for (var count = 0; count < 3; count++) { moveForward(); }</li> <li>Repeat the enclosed action until finish point is reached = if (isPathForward()) { moveForward(); }</li> </ol> Signup and view all the answers

Match the condition with the correct action:

<ol> <li>Check if there is a path forward = if (isPathForward()) { moveForward(); }</li> <li>Check if there is a path to the left = if (isPathLeft()) { turnLeft(); }</li> <li>Check if there is a path forward, otherwise turn left = if (isPathForward()) { moveForward(); } else { turnLeft(); }</li> <li>Execute actions based on path availability = if (isPathForward()) { moveForward(); }</li> </ol> Signup and view all the answers

Match the loop type with its functionality:

<ol> <li>Repeat a set of actions a specific number of times = for (var count = 0; count < 3; count++) { moveForward(); }</li> <li>Repeat actions while a certain condition is met = while (notFinished()) { moveForward(); turnLeft(); }</li> <li>Describe the purpose of using loops in programming = Using loops you can tell a computer to repeat any set of actions over and over, thousands or even billions of times.</li> <li>Specify the number of repetitions in a loop using a block = write a number in the block to tell it how many times to repeat.</li> </ol> Signup and view all the answers

Match the conditional statement with its corresponding behavior:

<ol> <li>Execute actions only if there is a path forward = if (isPathForward()) { moveForward(); }</li> <li>Turn left if no path forward exists = else { turnLeft(); }</li> <li>Choose between two sets of actions based on a condition = if (isPathForward()) { moveForward(); } else { turnLeft(); }</li> <li>Perform different actions based on specific conditions = if (isPathLeft()) { turnLeft(); }</li> </ol> Signup and view all the answers

Match the action with its description:

<ol> <li>Move the bird forward one space on the maze = moveForward();</li> <li>Turn right by 90 degrees = turnRight();</li> <li>Move forward and turn left for several iterations = while (notFinished()) { moveForward(); turnLeft(); }</li> <li>Move forward based on path availability = if (isPathForward()) { moveForward(); }</li> </ol> Signup and view all the answers

Match the task description with its corresponding solution:

<ol> <li>Repeating actions until reaching the finish point = if (isPathForward()) { moveForward(); }</li> <li>Moving forward multiple spaces using loops = for (var count = 0; count < 3; count++) { moveForward(); }</li> <li>Handling different scenarios with conditional statements = if (isPathLeft()) { turnLeft(); }</li> <li>Using loops to repeat actions in programming = Using loops you can tell a computer to repeat any set of actions over and over, thousands or even billions of times.</li> </ol> Signup and view all the answers
