What is the difference(s) between pointers and references?

Question

Int x = 2;
Int *pi = &x; //pointer
Int &y = x;//reference

Answer 1

Sir,
Pointers is a block of memory which does the job of storing memory address of another block of memory

Reference is a kinda function which does the job of taking memory address of a block of memory and then sending it into a pointor.

Pointers are useful because instead of coping the same data again and again you just take its address and use it to prevent unnecessary coping.

Answer 2

And Ya
Int * y = x; is wrong
Correct way is
Int * y = &x;

And by.
Int & y = x;
It does the same job as above *
But it automatically makes y a * and passes the memory address of x.
