Question

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

int cm = 24, dc  = 5, re = 8, bq = 1;

bq = cm/++dc + cm/re--; 

System.out.printn("CM=" +cm +"DC=" +dc+" RE=" +re +“BQ=" +bq);

Answer 1

cm/++dc 

++dc (Prefix): Increments dc first (from 5 to 6), then uses it.

24/6 = 4.

cm/re-- 

re-- (Postfix): Uses the current value of re (8) for the operation, then decrements re to 7.

• BQ = 4 + 3 = 7
• CM = 24
• DC = 6
• RE = 7
