C#.NET — Predict the output of the following ternary operator code: int a = 10, b = 20, c = 30; int res = a < b ? (a < c ? c : a) : b; Console.WriteLine(res);

Introduction / Context:
This question checks understanding of the conditional (ternary) operator ?: in C#. The operator evaluates a Boolean expression and returns one of two results.

Given Data / Assumptions:

• a = 10, b = 20, c = 30
• Expression: a < b ? (a < c ? c : a) : b

Concept / Approach:
Nested ternary operations must be carefully evaluated respecting parentheses and operator precedence. First the outer condition is tested, then the inner one.

Step-by-Step Solution:

Verification / Alternative check:
Compiling and running the code outputs 30, confirming correctness.

Why Other Options Are Wrong:
10 and 20 are wrong because conditions did not direct evaluation there. Compile error is wrong because syntax is valid.

Common Pitfalls:
Forgetting parentheses or misunderstanding evaluation order in nested ternary operators.

Final Answer:
30
