Pointer Example in C++


The variable that stores the address of another variable (like foo in the previous example) is what in C++ is called a pointer. Pointers are a very powerful feature of the language that has many uses in lower level programming.

Example Program:

Here is the simple program pointer in C++.

Source Code

using namespace std;
int main()
    int x=10;
    int *p;
    cout << "X : "<<x<<endl;
    cout << "&X : "<<&x<<endl;
    cout << "P : "<<p<<endl;
    cout << "&P : "<<&p<<endl;
    cout << "*P : "<<*p<<endl;
    return 0;

P : 0x7ffd640f347c
&P : 0x7ffd640f3480
*P : 10
