C++/Pointer/Auto Pointer
Demonstrate an auto_ptr.
#include <iostream>
#include <memory>
using namespace std;
class X {
public:
X() {
cout << "constructing\n";
}
~X() {
cout << "destructing\n";
}
void f() {
cout << "Inside f()\n";
}
};
int main()
{
auto_ptr<X> p1(new X), p2;
p2 = p1; // transfer ownership
p2->f();
X *ptr = p2.get(); // can assign to a normal pointer
ptr->f();
return 0;
}
Demonstrates the use of auto_ptr.
#include <iostream>
#include <memory>
using namespace std;
class MyClass {
public:
MyClass() {
cout << "constructing\n";
}
~MyClass() {
cout << "destructing\n";
}
void f() {
cout << "Inside f()\n";
}
};
int main()
{
auto_ptr<MyClass> myClassPointer1(new MyClass), myClassPointer2;
myClassPointer2 = myClassPointer1;
myClassPointer2->f();
MyClass *ptr = myClassPointer2.get();
ptr->f();
return 0;
}
