Defines a C ++ type pointer

#include <iostream>
using namespace std;

 

main int () {

int a = 10; // define variables a
int * P; // define pointers P
P = & a; // the address of a pointer P is equal to
int * o; // define a pointer O
O = & a; // o equal to a pointer address


cout << "a address is:" << endl << & a;
COUT << "P address is:" P << << endl;
COUT << "o address is : "<< endl << O;

* p = 1000; // pointer p is equal to the value in 1000

COUT <<" a = "<< endl << a;
COUT <<" * p = "<< * p < <endl;

return 0;
