as swim said it is a pointer to an array of 5 integers so one array of 5 integers is just one element
when I say ptr+1 in this case it will return an address that is after ptr by 5 integers not one
that is the difference

Sai Ram
it is not an array of pointers to integers why?
in this case sizeof(ptr) equals to sizeof(any pointer)
and sizeof(array of pointers) equals to sizeof(pointer)*n
where n is the number of elements in the array
so this is a single pointer to array not an array of pointers

its a pointer array.
the difference between array and a pointer array is
->Normal Array stores variable values .
->Pointer array stores address of the variables.

the precedence of bracket is first and associativity is left to right.
so read the 1st bracket - (*ptr) which means it is a pointer
then resolve 2nd bracket - [5] which means an array but you have got a pointer which means it is pointing to that array
and finally int denotes the datatype of values stored in the array
so ptr is a pointer to an array of 5 intergers
