Blockly Coding Challenge

What is the purpose of using loops in Blockly?

• To bake a cake

• To repeat a set of instructions multiple times.

• To predict the future

• To fly to the moon

How do you create a 'while' loop in Blockly?

• Use the 'switch' block from the Logic category.

• Use the 'while do' block from the Control category.

• Use the 'if else' block from the Logic category.

• Use the 'repeat' block from the Control category.

What is the difference between 'if' and 'else if' conditional statements in Blockly?

• The 'if' statement is used to execute a block of code if a specified condition is false, while the 'else if' statement is used to specify a new condition to test if the first condition is true.

• The 'if' statement is used to specify a new condition to test if the first condition is false, while the 'else if' statement is used to execute a block of code if a specified condition is true.

• The 'if' statement is used for false conditions, while the 'else if' statement is used for true conditions.

• The 'if' statement is used to execute a block of code if a specified condition is true. The 'else if' statement is used to specify a new condition to test if the first condition is false.

Explain the concept of 'nested' conditional statements in Blockly.

• Using conditional statements outside of loops

• Conditional blocks within other conditional blocks

• Using conditional statements without any logical operators

• Using conditional statements without any comparison

What is a function in Blockly and how is it used?

• A function in Blockly is a type of variable used to store data

• A function in Blockly is a reusable set of instructions that can be used to perform a specific task. It is used by dragging and dropping function blocks and connecting them to create a sequence of actions.

• A function in Blockly is a type of loop used to repeat a set of instructions

• A function in Blockly is a type of comment used to explain the code

How do you define a custom function in Blockly?

• By using the 'variables' category and creating a new custom block

• By using the 'math' category and creating a new custom block

• By using the 'loops' category and creating a new custom block

• By using the 'procedures' category and creating a new custom block with the desired functionality.

What is the significance of 'return' statement in a function?

• It ends the function execution

• It prints the output of the function

• It specifies the value that a function should return.

• It defines the function parameters

Explain the concept of 'parameters' in a function in Blockly.

• Parameters are the inputs that are passed into the function to perform a specific task.

• Parameters are not necessary in a function

• Parameters are only used in text-based coding, not in Blockly

• Parameters are the outputs of the function

How do you call a function in Blockly?

• By using the 'call' block and specifying the function name.

• By using the 'variable' block and specifying the function name.

• By using the 'if' block and specifying the function name.

• By using the 'print' block and specifying the function name.

What are the advantages of using functions in Blockly?

• Functions in Blockly increase the chance of errors

• Functions in Blockly make the code more confusing and difficult to understand

• Functions in Blockly do not help to organize and reuse code

• Functions in Blockly help to organize and reuse code, make it easier to read and understand, and reduce the chance of errors.
