Evaluate the Boolean expression in C#: what is assigned to c? int a = 10; int b = 20; bool c; c = !(a > b);

Introduction / Context:
This checks understanding of Boolean comparisons and logical negation in C# as well as proper typing of Boolean variables.

Given Data / Assumptions:

• a = 10, b = 20.
• Expression is !(a > b).
• c is of type bool.

Concept / Approach:
(a > b) evaluates to a Boolean. The operator ! negates a Boolean, flipping true to false and vice versa. C#'s bool is not an int; assigning 1 or 0 to bool is not the model—use true/false.

Step-by-Step Solution:

Verification / Alternative check:
Print c to the console; it outputs True.

Why Other Options Are Wrong:

• B: ! operates on bool, not int; there's no error.
• A: C# bools are not assigned 1/0; they hold true/false (though Convert.ToInt32(true) yields 1, that is a different API call).
• E: Opposite of the actual result.

Common Pitfalls:
Thinking of bool as an integer; in C#, bool is distinct and should be used with true/false.

Final Answer:
There is no error and c gets True.
