Question

This is about C#

If the following code segment compiles correctly, what do you know about the variable x?

if (x) Console.WriteLine("ok");

a. x is an integer variable

b. x is a boolean variable

c. x is greater than 0

d. none of these

I'm thinking it is d. none of these since when I input this into the console I get an error since X isn't declared. I am new to programming and C# so I'm unsure of solving too many problems. Thank you to everyone who takes time to read this. I appreciate it.

Answer 1

question is just asking about the segment of code.
so before we proceed - we need to assume here that x is declared and the segment is inside a class.

Answer 2

since in C# if condition only takes boolean expressions, x must be a boolean variable for the code segment to compile correctly.
