Difference between Arrays and Pointers GeeksforGeeks
Distinguishing Features of Arrays and Pointers 1 Behavior of sizeof operator When used with arrays sizeof operator returns the size in bytes occupied by the entire array whereas when used with pointers it returns the size in bytes of the pointer itself regardless of the data types it points to Example C C include iostream
Pointer to an Array Array Pointer GeeksforGeeks, This pointer is useful when talking about multidimensional arrays Syntax data type var name size of array Example int ptr 10 Here ptr is pointer that can point to an array of 10 integers Since subscript have higher precedence than indirection it is necessary to enclose the indirection operator and pointer name inside parentheses
