1. For the declarations below, which expression is TRUE if ptr1
and ptr2 point at the same object?
int *ptr1;
int *ptr2;
a. ptr1 == ptr2
b. None of the above is true
c. ptr1 != ptr2
d. &ptr1 == &ptr2
Homework Answers
a. ptr1 == ptr2 is true. ptr1 and ptr2 represent the address of the object. They both represent the same object. so, It gives TRUE.
Option c.ptr1!=ptr2 gives FALSE.
Because they both point to the same object and they are equal so it gives FALSE.
Option d. &ptr1 == &ptr2 is not correct. Because ptr1 and ptr2 are pointers. So *ptr is value and ptr is address. & is used for normal variables. the pointer doesn't need &.
