A3. Please do not use eclipse to generate the answer to this question. Read the code segment and calculate the result by hand.

(a) If x is currently 0, a = 7 and b = 6, what will x become after the following code segment is executed? And explain the reason.

(b) If x is currently 2, a = 7 and b = -5, what will x become after the following code segment is executed? And explain the reason.

if (x > 0)

if (b < 0)

x = x + 9;

else

if (a > 5)

x = x + 1;

else

x = x + 3;

else

x = x + 3;
