Pointers can only hold address?

Question

how is this possible?
int c; //declaration
int* pc = new c; // pointer pointing towards an address in heap
*pc=c; ( why not *pc= &c;)

Answer 1

*pc = c;

assigns the value of c to the value pointed by the address stored in pc.

*pc = &c;

is a common mistake made by beginners. (* should not be used here)

pc = &c;

assigns address of variable c to pointer pc.

Answer 2

When declaring your pointer, you can remove the new and it would be valid as well:

int c;
int* p_c = c;
