Chapter 2, Problem 4E

Explanation of Solution

 Given:

 Consider the value for the variables,

 u = 2, v = 3, w = 5, x = 7 and y = 11

 Evaluation for the expression:

 Expression #1:

 u + v * w + x

 Step 1:

 According to the operator precedence the first priority is multiplication

 = u + (v * ...

Explanation of Solution

 Expression #2:

 u + y % v * w + x

 Step 1:

 According to the operator precedence the first priority is modulus

 = u + y % v * w + x

 Now substitute the given value in the expression

 = 2 + (11 % 3) * 5 + 7

 = 2 + 2 * 5 + 7

 Step 2:

 ...

Explanation of Solution

 Expression #3:

 u++ / v + u++ * w

 Step 1:

 According to the operator precedence the first priority is division 

 = u++ / v + u++ * w

 Now substitute the given value in the expression

 = (2++ / 3) + 2++ * 5

 = (2 / 3) + 2++ * 5

 Here the java complier will take the value of “u” and divide it by “v”. So, the value becomes “0” but, the value of “u” is incremented by “1”...
