If they were each local to different functions (or different files) then they are in different 'scopes' then, YES then can have the same name.
Printing pointers. You can print a pointer value using printf with the %p format specifier. To do so, you should convert the pointer to type void * first using a cast (see below for void * pointers), although on machines that don't have different representations for different pointer types, this may not be necessary.
You need to initialize a pointer by assigning it a valid address. This is normally done via the address-of operator ( & ). The address-of operator ( & ) operates on a variable, and returns the address of the variable. For example, if number is an int variable, &number returns the address of the variable number .
The answer is "no", you cannot change the address of a variable.
They both the same. Only difference is that you cant declare many variables in such way:
int* x, a, b; //a and b are not pointers
int *x, *a, *b; //all are pointers
I use first notation, for me it shows that variable has pointer type, not pointer itself.

It's the same definition of pointer. both are pointer to an int
