C#.NET — After fixing spacing in the array creation (new int[]), what does this program print? namespace CuriousTabConsoleApplication { class SampleProgram { static void Main(string[] args) { int[] arr = new int[] { 1, 2, 3, 4, 5 }; fun(ref arr); } static void fun(ref int[] a) { for (int i = 0; i < a.Length; i++) { a[i] = a[i] * 5; Console.Write(a[i] + " "); } } } }

Introduction / Context:
The code multiplies each element of an integer array by 5, then prints the updated values. The ref keyword allows the method to receive a reference to the array, although arrays are reference types already.

Given Data / Assumptions:

• Initial array: {1, 2, 3, 4, 5}.
• Inside fun, each element is reassigned to element * 5.
• Console.Write prints each updated value followed by a space.

Concept / Approach:
Arrays are reference types; passing with ref is not required for modifying elements, but it permits reassigning the array variable itself. Here, only element values are changed.

Step-by-Step Solution:

Verification / Alternative check:
Run the loop manually or with a quick console application.

Why Other Options Are Wrong:

• 1 2 3 4 5: Shows the original values, not multiplied.
• 6 7 8 9 10 / 6 12 18 24 30: Do not match multiplication by 5.
• 5 25 125 625 3125: Represents powers of 5, not linear scaling.

Common Pitfalls:
Confusing element modification with creating a new array or power growth.

Final Answer:
