To understand the program of leap year, first we should understand the concept of leap year.

What is Leap Year?

A year which follow below conditions is known as leap year:

1. A year, which is divisible by 4 but not divisible by 100, is known as leap year.
2. A year, which is divisible by 4, 100 and 400, is known as leap year.
3. A year, which is divisible by 4, 100 but not divisible by 400 is not a leap year.

For example:

• 1604 is a leap year.
• 1605 is not a leap year.
• 1600 is a leap year.
• 1900 is not a leap year.

C# program to find the leap years from 1900 to 1950

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    
    class Program
    {
        static void Main(string[] args)
        {
            int i     = 0;

            for (i = 1900; i <= 1950; i++)
            {   
                if( 
                    ((i % 4==0) && (i % 100 !=0)) ||
                    ((i % 4==0) && (i % 100 ==0) && (i%400==0)) 
                  )
                {
                    Console.Write(i + " ");
                }
            }

            Console.WriteLine();
        }
    }
}

Output

1904 1908 1912 1916 1920 1924 1928 1932 1936 1940 1944 1948
