            catch (Exception d)
            {

1. The checked is not any keyword in C#.NET
2. We can use the unchecked keyword, but we cannot use the checked keyword in C#.NET
3. The checked keyword is used to check the overflow and conversion of integral type values
4. The checked keyword is used in older versions of the .NET framework

using System;

namespace my_namespace
{
    class program
    {
        static void Main(string[] args)
        {
            checked
            {
                int my_val = int.MaxValue;
                Console.WriteLine(my_val + 3);
            }
