Describe a scenario where using an array in C++ would be more beneficial than declaring multiple individual variables.

Multiple Choice

What is the significance of using arrays in C++ for managing data?

• They allow storing multiple values of the same type efficiently.

• They help in storing different types of data together.

• They automatically sort data.

• They eliminate the need for memory allocation.

Multiple Choice

Which of the following correctly declares an array of 10 integers in C++?

• int marks[10];

• float marks[10];

• char marks[10];

• int marks(10);

Multiple Choice

Which of the following statements about static and dynamic array initialization is correct?

• Static initialization assigns values at declaration, dynamic assigns values later.

• Dynamic initialization assigns values at declaration, static assigns values later.

• Both static and dynamic assign values at declaration.

• Neither static nor dynamic assign values at declaration.

Multiple Select

Select all correct statements about traversing arrays.

• Traversing means visiting each element of an array.

• A for loop can be used to traverse an array.

• A while loop cannot be used to traverse an array.

• Traversing is only possible for integer arrays.

How can you find the number of elements in an array using the sizeof() function in C++?

Multiple Choice

Which of the following statements correctly describes how the highest and lowest marks are found in the given program example?

• By comparing each mark to the current max and min values inside a loop.

• By sorting the array and picking the first and last elements.

• By using a built-in function to find max and min.

• By calculating the average and comparing each mark to it.

Multiple Select

Which of the following are valid ways to initialize a two-dimensional array in C++?

• int arr[2][3] = { {1,2,3}, {4,5,6} };

• int arr[2][3]; for(int i=0;i<2;i++) for(int j=0;j<3;j++) arr[i][j]=i+j;

• int arr[2][3] = {1,2,3,4,5,6};

• int arr[2][3] = {{1,2},{3,4},{5,6}};

How would you explain the concept of arrays in C++ to someone new to programming?

Multiple Choice

What is the main advantage of using arrays in C++?

• They allow you to manage multiple values of the same type efficiently.

• They allow you to use different data types in a single array.

• They automatically sort data.

• They eliminate the need for memory allocation.
