Why are arrays used?
A
Arrays store multiple data values under one name, reducing the complexity of our program
B
Arrays store more data than if we were using variables
C
Arrays store more data than if we were using strings
D
None of the above
Explanation: 

Detailed explanation-1: -Arrays help maintain large sets of data under a single variable name to avoid confusion that can occur when using several variables. Organizing data elements: Different array algorithms, like bubble sort, selection sort and insertion sort, can help you organize various data elements clearly and efficiently.

Detailed explanation-2: -Advantages of Array There isn’t any chance of extra memory being allocated if there is an array. This avoids the issue of overflow or shortage of memory. Other data structures like linked lists, stacks, queues, trees, and graphs can be accomplished using arrays.

Detailed explanation-3: -Arrays help to maintain large data under a single variable name. This avoid the confusion of using multiple variables.

Detailed explanation-4: -Arrays store multiple data of similar types with the same name. It allows random access to elements. As the array is of fixed size and stored in contiguous memory locations there is no memory shortage or overflow. It is helpful to store any type of data with a fixed size.
