pointers & array

[Cutefriendzoned]

Hey guys , is there a difference between number 1 and number 2 ?

  int array[10];
int *ptr=array; 

// the above is number 1

// here is number 2

int array[10];
int (*ptr)[10]=&array

number 1
it is initialization of pointer with adress of array array
ptr points to int array of length 10

number 2
it is initialization of two-dimensional int array with one-dimensional
you have an array of 10 pointers (because length of array is 10) and each of them points to int array with length of 10

The first ptr is a pointer to a single integer, which is initialized to point to the first element of array, that is, to array[0]

The second ptr is a pointer to the entire array of 10 int, which is initialized to point to the array array
