  • A A collection of different data types ✔ ✖
  • B A collection of same data type elements stored in contiguous memory ✔ ✖
  • C A function that stores multiple values ✔ ✖
  • D A pointer variable ✔ ✖
Correct Answer: Option B

Explanation

An array in C++ is used to store multiple values of the same data type in a continuous block of memory.

This allows easy access to elements using an index.

Example:

int a[3] = {10, 20, 30};

All elements are integers and are stored next to each other in memory.

Why other options are incorrect

  • A) Different data types ❌ → Arrays store only same data type

  • C) Function ❌ → Arrays are not functions

  • D) Pointer variable ❌ → An array is not a pointer (though related)

Correct Answer:

B) A collection of same data type elements stored in contiguous memory

Description:
Arrays store multiple values of the same type in consecutive memory locations for efficient access.
