C - Operators and Expressions

Given the expression int result = 10 - 3 * 2 + 4 / 2;, how can you change it using parentheses to make addition happen before multiplication?

Aint result = (10 - 3 * 2) + 4 / 2;

Bint result = 10 - (3 * (2 + 4 / 2));

Cint result = 10 - (3 * 2) + (4 / 2);

Dint result = (10 - 3 * 2 + 4) / 2;

Step-by-Step Solution

Solution:

Step 1: Understand original precedence
Multiplication and division happen before addition and subtraction.
Step 2: Use parentheses to change order
int result = 10 - (3 * (2 + 4 / 2)); groups 2 + 4 / 2 inside parentheses, forcing addition before multiplication.
Final Answer:
int result = 10 - (3 * (2 + 4 / 2)); -> Option B
Quick Check:
