If obj1 and obj2 are both objects of a class that uses dynamic memory allocation, but the class does not have an assignment operator, what happens if you execute the following code?
Obj1=obj2;
A) A syntax error occurs, you can not assign one object to another object without the = operator
B) A run-time error occurs, because the C++ system does not know how to do the assignment.
C) The pointers) to the dynamically declared memory in obj2 are copied to the corresponding pointers in obj1.
D) There is a complete and independent copy of all the dynamic memory from obj2 to obj1

When you assign one object to another without a user-defined assignment operator in C++, the default assignment operator is used. This operator performs a shallow copy, meaning it copies the values of the members of obj2 to obj1 directly, including the pointers to dynamically allocated memory. This does not create independent copies of the dynamic memory; both objects end up pointing to the same memory locations.
