    strange auto_ptr error

    In the following programme I'm using the auto_ptr pointer. All is good but when I try to print the value of the pointer, it prints out some memory location. Why?

    Code:
    #include <iostream>
    #include <memory>
    using namespace std;
    
    int main(int argc, char *argv[])
    {
        auto_ptr<int> number(new int);
        *number = 1;
        cout << "My number is " << number.get() << endl;
        
        cin.get();
        return(0);
    }

    auto_ptr::get() returns the value of the pointer which is the location that the object is stored. Your printing out the memory location of the object.

    to get the actual value u already know how to do it

    Code:
    cout << "My number is " << *number << endl;
