C#.NET — What will this program print when it tries to write a[6] (array size 5)? using System; namespace CuriousTabConsoleApplication { class MyProgram { static void Main(string[] args) { int index = 6; int val = 44; int[] a = new int[5]; try { a[index] = val; } catch (IndexOutOfRangeException e) { Console.Write("Index out of bounds "); } Console.Write("Remaining program"); } } }
-
AValue 44 will get assigned to a[6].
-
BIt will output: Index out of bounds
-
CIt will output: Remaining program
-
DIt will not produce any output.
-
EIt will output: Index out of bounds Remaining program
Answer
Correct Answer: It will output: Index out of bounds Remaining program
Explanation
Introduction / Context:This problem tests your knowledge of array bounds and specific exception handling with IndexOutOfRangeException in C#. It also checks whether you understand that execution continues after a handled exception.
Given Data / Assumptions:
- Array declared as new int[5] has valid indices 0..4.
- Code attempts to write to a[6].
- There is a catch (IndexOutOfRangeException) and a print after the try/catch.
Concept / Approach:Attempting to access index 6 on a 5-element array throws an IndexOutOfRangeException. The catch block prints a message and execution then proceeds to the statement after the catch, printing the final text. Thus, two messages appear, in order.
Step-by-Step Solution:
Array length = 5 → allowed indices 0..4.Access a[6] → throws IndexOutOfRangeException.Catch executes: prints "Index out of bounds ".After catch, prints "Remaining program".Verification / Alternative check:Changing index to a legal value (such as 4) would print only "Remaining program" because the catch would not run.
Why Other Options Are Wrong:
- Assignment succeeds: impossible because index 6 is invalid.
- Only one of the messages: ignores continued execution after a handled exception.
- No output: the program prints in both paths.
Common Pitfalls:Confusing length with highest index (highest index is Length - 1). Also, forgetting that a handled exception allows the program to continue.
Final Answer:It will output: Index out of bounds Remaining program
