Question

Answer

Definition of Array
An array is a data structure that stores a fixed-size sequential collection of elements of the same type. In other words, an array is a container that holds a fixed number of items of the same data type.

Features of Array
Some of the key features of an array include:

- Homogeneous: All elements of an array must be of the same data type.
- Contiguous memory allocation: Array elements are stored in contiguous memory locations.
- Fixed size: The size of an array is fixed and cannot be changed once it is initialized.
- Index-based: Each element in an array is identified by its index, which starts at 0.

Uses of Array
Arrays are commonly used in programming for tasks such as:

- Storing and accessing collections of data
- Sorting and searching algorithms
- Implementing matrices and other mathematical structures
- Implementing dynamic programming algorithms

Advantages of Array
Arrays offer several advantages, including:

- Random access: Elements in an array can be accessed directly using their index, which makes accessing and modifying elements fast and efficient.
- Compact memory usage: Since all elements of an array are stored in contiguous memory locations, an array uses memory efficiently.
- Easy to implement: Arrays are simple to implement and use, making them a popular choice for many programming tasks.

Conclusion
In summary, an array is a container of objects of similar types. It is a simple data structure that stores a fixed-size sequential collection of elements of the same type. Arrays are widely used in programming for a variety of tasks, and offer several advantages such as random access, compact memory usage and ease of implementation.

Answer

Array contains elements only of the same type.
