NettetWorking. The value of a is 20 and b is 16. The condition (a > 10) is true, so the execution enters the if block. The statement a = a++; increments the value of a by 1 after the assignment. So a remains unchanged as we are assigning the original value of a (which is 20) back to a. The value of b is incremented by 1 so b becomes 16. Answered By.
