Question 7: Illustrate I3 is a copy constructor
and the values are exactly equal to that of variable I1,
as this variable is instantiated with I1.
As, I1 is instantiated with x value of 3 in line 1 of main().
x value is 3.
y value is initialized with 0.
As incrementY() is called at line 4 of main(), the variable y is
revised to 1.
As count variable is incremented at line 9, the variable count is
incremented from 0 to 1.
So, at line 13, the values are:
I3: x = 3, y = 1, count = 1
Next Question:
A is an array of type ArrayClass of size 2 elements, at line
31.
A[0] is initialized with values in object A1, at line 32.
A[1] is initialized with values in object A2, at line 33.
Just to mention, A2 is an object with values with x,
and y both set to 5 at line 30.
A[0].x value is incremented, which updates x value to 6 at line
34.
However, as you didn't updated
A[1] value, it will remain the same, and therefore,
after line 34, the contents of object A[1] are:
x = 5, y = 5.
Question 10:
At line 1, I1 is initialized with x = 3, y = 0, count = 0.
At line 2, I2 is initialized with x = 5, y = 0, count = 0.
At line 4, incrementY() will increment the y value of Illustrate
class from 0 to 1.
Therefore, after line 4,
I1: x = 3, y = 1, count = 0.
I2: x = 5, y = 1, count = 0.
Note that y is a static variable and will be the same for all
instances.
