Understanding Arrays in Programming

Why do arrays have a bad reputation among students?

• They are too simple.

• They are not useful.

• They are difficult to understand.

• They are rarely used in programming.

What is the main advantage of using arrays?

• They are not compatible with loops.

• They make the code longer.

• They simplify storing multiple values.

• They are only useful for small data sets.

How can you store multiple scores in an array?

• By using separate variables for each score.

• By using a single variable.

• By using an array to hold all scores.

• By using a loop to create variables.

How do you access the fourth element in an array?

• By using the index 1.

• By using the index 3.

• By using the index 4.

• By using the index 2.

What is the result of accessing the third element in an array?

• The fourth element.

• The third element.

• The first element.

• The second element.

How do you update the value of the third element in an array to zero?

• score[3] = 0

• score[2] = 0

• score[1] = 0

• score[0] = 0

What is the purpose of using square brackets with arrays?

• To print an array.

• To access elements in an array.

• To declare an array.

• To delete an array.

How can you print all elements in an array using a loop?

• By using a for loop.

• By using a while loop.

• By using a switch statement.

• By using an if statement.

What function is used to get the number of items in an array?

• array.size()

• array.count()

• array.length()

• array.items()

What is one of the main benefits of using arrays in large programs?

• They require more memory.

• They are only useful for small data sets.

• They allow for easy scaling.

• They make the code more complex.
