C#.NET — What will this program print if the user enters "6" for the index? using System; namespace CuriousTabConsoleApplication { class MyProgram { static void Main(string[] args) { int index; int val = 44; int[] a = new int[5]; try { Console.Write("Enter a number:"); index = Convert.ToInt32(Console.ReadLine()); a[index] = val; } catch (FormatException e) { Console.Write("Bad Format"); } catch (IndexOutOfRangeException e) { Console.Write("Index out of bounds"); } Console.Write("Remaining program"); } } }

Difficulty: Easy

Correct Answer: It will output: Index out of bounds Remaining program

Explanation:


Introduction / Context:
This question examines multiple catch blocks and ensures you select which one will execute based on the runtime error condition when indexing beyond the array bounds.



Given Data / Assumptions:

  • User inputs "6".
  • Array length is 5, so valid indices are 0..4.
  • There are two catch blocks: FormatException and IndexOutOfRangeException.
  • There is a final print after the try/catch sequence.


Concept / Approach:
Convert.ToInt32("6") succeeds and yields 6, so no FormatException occurs. Writing a[6] triggers IndexOutOfRangeException. Therefore, the second catch executes, then the program continues and prints the final message.



Step-by-Step Solution:

Parse input "6" → index = 6 (no FormatException).Attempt a[6] = 44 → throws IndexOutOfRangeException.catch (IndexOutOfRangeException) runs → prints "Index out of bounds".Control moves after try/catch → prints "Remaining program".


Verification / Alternative check:
Test with input "abc": the FormatException catch runs. Test with input "4": neither catch runs and only "Remaining program" prints.



Why Other Options Are Wrong:

  • Bad Format options assume parsing failed; it did not.
  • Only one of the two messages ignores normal continuation after a handled exception.


Common Pitfalls:
Assuming the first catch always runs. Catch selection depends on the actual exception type thrown.



Final Answer:
It will output: Index out of bounds Remaining program
