14. Pointers and arrays

• Pointers and arrays are closely related. For example,

  
     char* ptr = "hello";  // pointer
     char arr[] = "hello"; // array
  
  

• Null character is also included in the array, so sizeof(arr) returns 6:

   

  arr[0]	arr[1]	arr[2]	arr[3]	arr[4]	arr[5]
  H	E	L	L	O	\0
