IGDTUW 2025 — Computer PYQ

Solution

The correct answer is (b) 15.

Part 1 ($a++$): Uses current value $5$, then $a$ becomes $6$.

Part 2 ($--a$): $a$ (currently $6$) is decremented first, becoming $5$. Value used is $5$.

Part 3 ($a++$): Uses current value $5$, then $a$ becomes $6$.

Total for $b$: $5+5+5=15$.
