## What is an array how arrays are represented in computer memory?

An array is a collection of homogeneous (same type) data items stored in contiguous memory locations. For example if an array is of type “int”, it can only store integer elements and cannot allow the elements of other types such as double, float, char etc.

What is array and how array is represented in memory?

Memory Allocation of the array As we have mentioned, all the data elements of an array are stored at contiguous locations in the main memory. The name of the array represents the base address or the address of first element in the main memory. Each element of the array is represented by a proper indexing.

How linear array is represented in memory?

A linear array, is a list of finite numbers of elements stored in the memory. Elements of the array form a sequence or linear list, that can have the same type of data. Each element of the array, is referred by an index set. And, the total number of elements in the array list, is the length of an array.

### What are the types of arrays?

There are three different kinds of arrays: indexed arrays, multidimensional arrays, and associative arrays.

What are the limitations of array?

Limitations

• An array which is formed will be homogeneous.
• While declaring an array, passing size of an array is compulsory, and the size must be a constant.
• Shifting is required for insertion or deletion of elements in an array.

What is multidimensional array?

A multidimensional array in MATLAB® is an array with more than two dimensions. In a matrix, the two dimensions are represented by rows and columns. Multidimensional arrays are an extension of 2-D matrices and use additional subscripts for indexing. A 3-D array, for example, uses three subscripts.

## What is array advantage and disadvantage?

Advantages of Arrays In an array, accessing an element is very easy by using the index number. The search process can be applied to an array easily. 2D Array is used to represent matrices. For any reason a user wishes to store multiple values of similar type then the Array can be used and utilized efficiently.

What are the arrays explain?

An array is a data structure, which can store a fixed-size collection of elements of the same data type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.
