What is the difference between array and pointer variable in what way are they similar?
An array is a collection of elements of similar data type whereas the pointer is a variable that stores the address of another variable. An array size decides the number of variables it can store whereas; a pointer variable can store the address of only one variable in it.
How does C structure differ from array?
A structure is a user defined data type in C/C++….Difference between Structure and Array.

|---|---|
| Array elements are stored in continuous memory locations. | Structure elements may or may not be stored in a continuous memory location. |
How is an element in an array different from the element in a linked list?
An array is a collection of elements of a similar data type. A linked list is a collection of objects known as a node where node consists of two parts, i.e., data and address. Array elements store in a contiguous memory location. Linked list elements can be stored anywhere in the memory or randomly stored.
What is an array variable?
A variable array is a group of variables stored under the same name but with different index values. Each array element has a name (which is p in this example, the same as the array name) and an index (between brackets) that makes it possible to select an element. …

What’s the difference between array and structure in C + +?
In C++, there is strict bound checking on arrays; you can not store elements in an array, out of its bound. Here, the type describes the data type of an array and, size defines the capacity of an array. Let’s declare an array of integer type and size 10, i.e. it will hold ten elements. The indexing in arrays starts from “0” up to “size-1”.
