#includeIn this example, the `boost::shared_ptr` template takes care of destroying the `Foo` object when it is no longer needed. The reference count for the object is incremented when a new `shared_ptr` is created, and decremented each time a `shared_ptr` goes out of scope. The SPtr class template is commonly found in libraries that provide smart pointer functionality, such as Boost, TR1, and the C++11 standard library. Its use can help prevent memory leaks and make code more robust and maintainable.#include "Foo.h" int main() { boost::shared_ptr fooPtr(new Foo()); // Do something with the Foo object... ... // The Foo object's memory is automatically deallocated // when fooPtr goes out of scope. return 0; }
