Pointer

Question

I read somewhere that :
int c, *ptr;
*ptr = &c; // is wrong, coz *ptr is the value pointed by address whereas &c is an address.
But there are many tutorials out there which uses that.
why is that?

Answer 1

Correct is ptr=&c;
*ptr is the value at the address
when you assign an address (&c) you assign it to ptr directly
