What is the purpose of the switch...case statement in Arduino?

• To repeat a block of code multiple times
• To define a function
• To select one of many code blocks to be executed based on a variable's value
• To pause program execution for a specific time
• To declare an array

What does the following code snippet do? <br> while (count < 10) {<br> // Code to be executed<br> count++;<br> }

• Executes the code block 9 times
• Executes the code block 10 times
• Executes the code block 11 times
• Executes the code block indefinitely
• Causes a compile-time error

What is the purpose of the break; statement in a switch...case structure?

• To skip to the next case
• To exit the entire program
• To exit the switch...case structure
• To pause program execution
• To define a new variable

What is the purpose of the continue; statement in a loop?

• To exit the loop completely
• To skip the rest of the current iteration and proceed to the next
• To pause loop execution
• To define a new variable
• To restart the loop from the beginning

What is the correct way to declare an array of 5 integers named myArray in Arduino?

• int[5] myArray;
• myArray int[5];
• int myArray{5};
• int myArray[5];
• array myArray[5];

What does the following code snippet do? <br> for (int i = 0; i < 5; i++) {<br> myArray[i] = i * 2;<br> }

• Fills the array with random numbers
• Fills the array with the numbers 0 to 4
• Fills the array with the numbers 0, 2, 4, 6, 8
• Fills the array with the numbers 2, 4, 6, 8, 10
• Causes a compile-time error

What is the index of the last element in an array of size 10?

• 10
• 9
• 1
• It depends on the data type of the array

What is the purpose of a function in Arduino programming?

• To store data
• To define a constant
• To group a block of code for reusability
• To control program flow
• To declare variables

What does the return statement do in a function?

• Indicates the start of the function
• Defines the parameters of the function
• Ends the function and optionally returns a value to the caller
• Declares a local variable within the function
• Prints a value to the Serial Monitor

What is the purpose of the void keyword in a function definition?

• To indicate that the function does not take any arguments
• To indicate that the function does not return any value
• To define a global variable
• To declare a constant
• To include a library
