C#.NET — Given the struct below, which is the correct way to assign values to its fields? struct Emp { public string name; public int age; public Single sal; } Emp e = new Emp();

Difficulty: Easy

Correct Answer: e.name = 'Amol'; e.age = 25; e.sal = 5500;

Explanation:


Introduction / Context:
The question checks familiarity with C# field assignment syntax versus constructs from other languages (VB, C/C++).



Given Data / Assumptions:

  • A public struct Emp exposes three public fields.
  • We have an initialized variable e = new Emp().


Concept / Approach:
In C#, field assignment uses the dot operator on the variable: e.name = "Amol"; e.age = 25; e.sal = 5500; Features like With blocks are from VB, and the arrow operator is from C/C++ pointer syntax, neither of which applies to C# field assignment.



Step-by-Step Solution:

Use e.name, e.age, e.sal with standard assignment.Avoid VB-style With or C/C++ -> syntax; they are invalid in C#.


Verification / Alternative check:
Compile only the candidate from Option A; it succeeds. The others produce syntax errors in C#.



Why Other Options Are Wrong:

  • B/C: VB-like With blocks are not part of C#.
  • D: The arrow operator dereferences pointers in C/C++; not valid for managed struct variables in C#.
  • E: Missing the variable qualifier (e); invalid context for assignments.


Common Pitfalls:
Bringing habits from other languages into C# syntax.



Final Answer:
e.name = 'Amol'; e.age = 25; e.sal = 5500;
