Coding Adventure III Quiz

What does the Boolean operator 'not' do?

• Returns a value for further use

• Compares two values

• Reverses the result of a condition

• Triggers actions based on user input

Answer explanation

The Boolean operator 'not' reverses the result of a condition. If a condition is true, 'not' makes it false, and vice versa, effectively inverting the logical value.

Which operator checks if two values are equal?

• not

• ==

• >

• <

What is the purpose of comparison operators?

• To trigger events

• To compare values

• To return values

• To define functions

Answer explanation

Comparison operators are used to compare values, determining their relationship (e.g., equal, greater than). This is essential in programming for decision-making and control flow.

What does the function 'health()' return?

• If the banana is rotten

• Whether the monkey is near an object

• The monkey's health

• The distance to an object

Answer explanation

The function 'health()' specifically returns the monkey's health, indicating its well-being. This is the most relevant choice among the options provided.

Which event is triggered when a key is pressed?

• onKey

• onClick

• onHover

• onMouseMove

Answer explanation

The event triggered when a key is pressed is 'onKey'. This event specifically captures keyboard actions, while 'onClick', 'onHover', and 'onMouseMove' relate to mouse interactions.

What does the operator '<' do?

• Checks if the left value is greater than the right

• Checks if two values are equal

• Checks if the left value is less than the right

• Reverses a condition

Answer explanation

The operator '<' checks if the left value is less than the right value. Therefore, the correct choice is that it checks if the left value is less than the right.

What is the function of 'onMouseMove'?

• Triggered when the mouse is clicked

• Triggered when the mouse is moved

• Triggered when a key is pressed

• Triggered when the game starts

Answer explanation

The 'onMouseMove' function is specifically designed to respond to mouse movements, making the correct answer 'Triggered when the mouse is moved'. The other options refer to different events.

Which function returns 'yes' or 'no' based on the monkey's proximity to an object?

• distanceTo

• near

• health

• frozen

Answer explanation

The function 'near' checks the monkey's proximity to an object and returns 'yes' or 'no' accordingly. The other options do not serve this purpose.

What does the 'onClick' function do?

• Checks health status

• Handles mouse movement

• Moves the character

• Handles mouse click events

Answer explanation

The 'onClick' function is specifically designed to handle mouse click events, allowing developers to define actions that occur when a user clicks on an element. This makes it essential for interactive web applications.

What is the main application of functions with return?

• To compare values

• To trigger events

• To determine game actions based on returned values

• To reverse conditions

Answer explanation

Functions with return values are primarily used to determine game actions based on those values. They allow the program to make decisions and execute specific actions depending on the results returned.
