The most common thing is that we can reload the new operator in the class, in this case, if something else is called in the operator = new () function, free will not work normally, or will also cause memory leakage. Let's take a few simple examples: Class CTest {public: CTest ();~ CTest (); private: int * _ m_pn;}; CTest: CTest () {_ m_pn = new int [128]; assert (_ m_pn );} CTest ::~ CTest () {assert (_ m_pn); delete [] _ m_pn; _ m_pn = NULL;} int main () {int *

The process already occupies at least one resource, but it also applies for new resources; Because the resource is already occupied by another process, the process is blocked at this time, but it continues to occupy the resources it has already occupied while waiting for new resources.
