1. Write a program that demonstrates the operator ++ by performing the following

tasks:

• Use Scanner to read an Integer value
x.

• Compute
x++ and store the result in
y.

• Display
x
and
y
clearly labeled.

• Compute ++x
and store the result in
z.

• Display
x
and
z
clearly labeled.

Try your program with positive and negative values of
x. What can you

conclude about pre and post increment?

2. If u = 1, v = 2, w = 3, × = 4, and y = 10, what is the value of each of the

following expressions, assuming int variables?

• u - v * (w + x)

• u + y / v * (w + x)

• ++v / (v + u) * w
