Which of the following statements is correct about the C#.NET code snippet given below? 
int d; 
d = Convert.ToInt32( !(30 < 20) );
A value 0 will be assigned to d.
A value 1 will be assigned to d.
A value -1 will be assigned to d.
The code reports an error.
The code snippet will work correctly if ! is replaced by Not.
Answer: Option
Explanation:

Sample Program:

bool falseFlag = false;
bool trueFlag = true;

Console.WriteLine("{0} converts to {1}.", falseFlag,
                  Convert.ToInt32(falseFlag));
Console.WriteLine("{0} converts to {1}.", trueFlag,
                  Convert.ToInt32(trueFlag));
The example displays the following output:

       False converts to 0.
       True converts to 1.

In our expression we are checking a Boolean which give us true or false say that is 30 is not less than 20 it evaluates to true and then we are converting to integer that get the value of 1.

When we solve the expression in bracket we get 0 and notting 0 that is value false and notting it we get value true and in c# true means in integer value is one hence the true value get converted into 1 hence answer is B.
