C#.NET — Choose the correct way to declare and initialize a variable of the struct Emp. struct Emp { private string name; private int age; private float sal; } Which one of the following single-line or two-line snippets correctly declares a variable and initializes it?

Introduction / Context:This question asks for a correct declaration/initialization pattern for a user-defined struct Emp. For parameterless construction of a struct, C# permits using new Emp() to create a zero-initialized instance, invoking the implicit parameterless initializer logic for value types (unless an explicit parameterized constructor is defined).

Given Data / Assumptions:

• Emp is a struct (value type) with three private fields.
• We want one correct way to both declare and initialize a variable.

Concept / Approach:For value types, you can either declare a variable and then assign with new Emp(), or perform both in one statement. The keyword new zero-initializes all fields. Syntax must include parentheses when calling the parameterless initializer for a struct. The distractors either omit parentheses, reverse assignment, or use signatures that do not compile in C#.

Step-by-Step Solution:

Verification / Alternative check:If desired, the two-line valid equivalent is: Emp e; e = new Emp(); which also compiles and creates a zero-initialized struct instance.

Why Other Options Are Wrong:

• A: Not a variable definition in C#.
• B/C: Missing parentheses after Emp; does not compile.
• E: Assignment direction is invalid; left side must be a variable.

Common Pitfalls:Forgetting parentheses when using new with structs; confusing C# syntax with C/C++ forms; misreading “Emp e();” as a variable instead of a method-like form.

Final Answer:Emp e = new Emp();
