After deleting the object, calling the method of the object does not report an error

   After deleting an object, executing the method of the object will not report an error, but return an indeterminate value.

 

/*After testing the delete MyVector object, execute the is_eof() function to see if it has ended*/

#include "vector.h"


using uint32 = unsigned int;

int main(){

    MyVector<uint32> * mv = new MyVector<uint32> ();

    mv->start_write();
    mv->push_back(1);
    mv->push_back(2);

    mv->start_read();
    while(!mv->is_eof()){

        std::cout << mv->get() << " ";
        mv->next_remove();
    }

    delete mv;

    if( mv->is_eof() )std::cout << " is_eof() is true.\n";
    else std::cout << " is_eof() is false.\n";
