can anybody explain the difference between * and &

Question

pointers

Answer 1

You can read:

* as 'point-to'
& as 'address-of'

E.g.

int x = 5;
int* p;
p = &x;

cout << *p << endl;
cout << *&x << endl;
cout << &x << endl;

// the above can be read as:
/*

Declare x as integer variable which stores 5.
Declare pointer p of type integer.
Store the address of x into pointer p.

Point to address stored in p, and print the value.
Point to the address of x, and print the value.
Print the address of x.

Answer 2

@yuri They are all the same.

Answer 3

* is used to declare a pointer variable like
int *point =....... ;
now & is ampersand operator u can use it to get the memory location like-
int *point = &var;

note: * is also used as a dereference operator this means that it is used to get value which is stored in that memory location like
*point;

Answer 4

just for clarification. are these the same:
1) int* p = &x;
2) int *p;
p = &x;
and another question.
where the space is to be :
int* p; or int *p; are they the same?

Answer 5

" * " denotes that the variable is pointer that stores the address of another variable while " & " is used to access the address of variable.
for example :
int a:
int *ptr;
*ptr = &a;
here *ptr is holding the address of integer a and &is used to access its address.
