Declaration of typedef as declaration integer i.e.
int a,*b;
Similarly typedef can also be declare typedef no,*prtono
Here two variable declared i.e no which only data type and prtono that is pointer type variable.
int a,*b;
Similarly typedef can also be declare typedef no,*prtono
Here two variable declared i.e no which only data type and prtono that is pointer type variable.

Here, ptrtono is declared as a pointer
but in third line(ptrtono p;) is wrong because, we have to use & operator to store a pointer value.
So the correct form is(ptrtono &p;).
Correct me if I am wrong.

I am not sure of this but typedef long *ptr; <=> typedef(long*)ptr; here we are declaring ptr as as a long pointer.
Now typedef long no. is using no to replace long.

We are giving two different names to long i.e no and *prtono.
Either of these can be used to declare long variable.
Either of these can be used to declare long variable.

In the program declaring the 2 data types.
i.e : no, *ptrono;
Then we declaring the variables for them.
i.e : no, *ptrono;
Then we declaring the variables for them.

We are using no as long ptrtono as long pointer like long *.
So no as long and prttono as long *.
So no as long and prttono as long *.
