Question

Evaluate the following expression where prefix and postfix increment and decrement operator is used.

int b = 6, d = 12,c = 0; 

c = b++ + d-- + ++ b; 

System.out.println ("B=" + b+" D=" + d+" C=" +c);

Answer 1

1. b++ (Postfix): Uses the current value of b (6) in the expression, then increments b to 7.
2. d-- (Postfix): Uses the current value of d (12) in the expression, then decrements d to 11.
3. ++b (Prefix): Increments b first (from 7 to 8), then uses this new value (8) in the expression.

• C = 6 + 12 + 8 = 26
• B = 8
• D = 11
