In C#.NET if we do not catch the exception thrown at runtime then which of the following will catch it?

1. The program did not handle an exception called IndexOutOfRangeException.
2. The program execution continued after the exception occurred.
3. The exception occurred in line number 14.
4. In line number 14, the program attempted to access an array element which was beyond the bounds of the array.
5. The CLR could not handle the exception.

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");
        }
    }
}

using System;
namespace CuriousTabConsoleApplication
{
    class MyProgram
    {
        static void Main(string[] args)
        {
            int index; 
            int vat = 88;
            int[] a = new int(5];
            try
            {
                Console.Write("Enter a number: ");
                index = Convert.Toint32(Console.ReadLine());
                a[index] = val;
            }
            catch(Exception e)
            {
                Console.Write("Exception occurred");
            }
            Console.Write("Remaining program");
        }
    }
}

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.Tolnt32(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");
        }
    }
}

1. If our program does not catch an exception then the .NET CLR catches it.
2. It is possible to create user-defined exceptions.
3. All types of exceptions can be caught using the Exception class.
4. CLRExceptions is the base class for all exception classes.
5. For every try block there must be a corresponding finally block.

1. If an exception occurs then the program terminates abruptly without getting any chance to recover from the exception.
2. No matter whether an exception occurs or not, the statements in the finally clause (if present) will get executed.
3. A program can contain multiple finally clauses.
4. A finally clause is written outside the try block.
5. finally clause is used to perform clean up operations like closing the network/database connections.
