If obj1 and obj2 are both objects of a class that uses dynamic memory allocation, but the class does nohave an assignment operator, what happens if you execute the following code? obj1 =obj2; 50)
a)a syntax error occurs, you cannot assign one object to another object without the =operator. b)there is a complete and independent copy of all the dynamic memory from obj2 to obj1.c)the pointer(s) to the dynamically declared memory in obj2 are copied to the correspondingpointers in obj1.d)a run-time error occurs, because the c++system does not know how to do the assignment
