Answer & Solution
Answer: Option A
Solution:
Explanation: The correct answer is
A: int.
Value Types vs. Reference Types: In C#, data types are categorized into two main groups: value types and reference types.
Value Types:
* Value types directly store the data within their own memory space.
* When you copy a value type variable, you are creating a completely independent copy of the data.
* Examples of value types include:
int,
float,
bool,
char,
struct, and
enum.
Reference Types:
* Reference types store a *reference* (or pointer) to the memory location where the actual data is stored.
* When you copy a reference type variable, you are only copying the reference, not the data itself. Both variables will then point to the same location in memory.
* Examples of reference types include:
string,
class,
object,
arrays, and
interfaces.
Why the other options are incorrect:
*
B: string - Strings are
reference types in C#.
*
C: class - Classes are used to define objects, and they are
reference types.
*
D: object - 'object' is the base class for all types in C#, and it is a
reference type.
