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 pointer(s) 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
d. There is a complete and independent copy of all the dynamic memory from obj2 to obj1

Which of the following statements is true?
Segment A int q = 5; switch(q) { case 1: System.out.println(1); case 2: System.out.println(2); case 3: System.out.println(3); case 4: System.out.println(4); case 5: System.out.println(5); default: System.out.println("default"); } Segment B q = 4; switch(q) { case 1: System.out.println(1); case 2: System.out.println(2); case 3: System.out.println(3); case 4: System.out.println(4); case 5: System.out.println(5); default: System.out.println("default"); a. The output for Segment A is: default b. The output for Segment B is: 4 c. The output for Segment B is: 45default d. The output for Segment A is: 5 default
What operator is used to access the value of a single variable? by the use of a pointer variable?
A. -> B. & C. * D. You need more than one of these.
You can use the ____________________ attribute to apply the same class to more than one column.
Fill in the blank(s) with the appropriate word(s).
