Why we use enum?

In enum here a=1,hence then b will be 2 and c will be 3.
x=3.
y=3.
z=3.
y=2 i.e.
x=2 i.e.
z=2.
And decrement operator will effect only after the output !
Thus output = 2.
x=3.
y=3.
z=3.
y=2 i.e.
x=2 i.e.
z=2.
And decrement operator will effect only after the output !
Thus output = 2.

Because here we used enum. In enum when we initialized variable the value will be in incremented order.

Why the value of x, y, z is 3?

x=3
y=3
z=3
y=2 i.e.
x=2 i.e.
z=2
And decrement operator will effect only after the output !
Thus output = 2.
But z = 1.
y=3
z=3
y=2 i.e.
x=2 i.e.
z=2
And decrement operator will effect only after the output !
Thus output = 2.
But z = 1.
