What is the similarity between array and pointer variable?
|Memory allocation is in sequence.||Memory allocation is random.|
|Allocates the memory space which cannot resize or reassigned.||Allocated memory size can be resized.|
|It is a group of elements.||It is not a group of elements. It is a single variable.|
How arrays and pointers are related?
An array is represented by a variable that is associated with the address of its first storage location. A pointer is also the address of a storage location with a defined type, so D permits the use of the array [ ] index notation with both pointer variables and array variables.
What are the similarities between strings and arrays?
Strings are similar to arrays with just a few differences. Usually, the array size is fixed, while strings can have a variable number of elements. Arrays can contain any data type (char short int even other arrays) while strings are usually ASCII characters terminated with a NULL (0) character.
What is difference and relation between array and pointer?
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.
What is array differentiate between array and pointer?
Difference Between a Pointer to an Array and Array of Pointers
|Parameters||Pointer to an Array|
|Uses and Purposes||A user creates a pointer for storing the address of any given array.|
|Type of Storage||A typical pointer variable is capable of storing only a single variable within.|
What is the relationship between an array and a pointer in C?
Array in C is used to store elements of same types whereas Pointers are address varibles which stores the address of a variable. Now array variable is also having a address which can be pointed by a pointer and array can be navigated using pointer.
When the pointers are used for character array or strings, then it is called as string pointers. It works similar to any other array pointers. When we increment or decrement string pointers, it increments or decrements the address by 1 byte.
