Arrays-Day2

In this repo, we will understand about Arrays and some simple Problem related to it.

Whar is Array?

• Arrays is collection of same types of data/elements.
• It allows contiguous memory location.
• Easy access of element by using index.

How to declare an array?

data_type array_name [size];
eg -> int arr[10];

Initialization

Case 1 :

    int arr[] ={1,2,3,4,5};

Case 2:

    int arr[5] = {1,2,3};
 rest of elements will be zero.   

Case 3:

  for(int i=0;i<n;i++)
       cin >> arr[i];
   * Run time.

Dynamic Memory Allocation

• Size of array can be change during runtime.
• Free the allocated memory.
• C defines some library functions under the library stdlib.h
  

malloc()

used to dynamically allocate single large block of memory.

• It returns void pointer.

free()

used to deallocate dynamically allocated memory.

• free(p);
