Which expression correctly assigns the maximum of a and b to m using the ternary operator?

• A. int m = (a > b) ? a : b;
• B. int m = a > b ? b : a;
• C. int m = (a < b) ? b : a;
• D. int m = max(a, b);

Answer: (A)

Using the ternary operator, you choose between two values based on a condition. To get the maximum of a and b, check if a is greater than b; if true, the maximum is a, otherwise it’s b. So the expression is int m = (a > b) ? a : b;. The parentheses around the condition help readability and ensure the comparison is evaluated before selecting the result. The alternative form that swaps the branches would return the smaller value when a > b, which is not the max.
