Find Century of Year

Write a C# program to get the century of a year.

Sample Solution:

C# Sharp Code:

using System;

public class Exercise
{
    // Function to calculate the century from a given year
    public static int centuryFromYear(int year)
    {
        // Calculation of the century by dividing the year by 100 and adding 1 if there's a remainder
        return (int)(year / 100) + ((year % 100 == 0) ? 0 : 1);
    }

    public static void Main()
    {
        // Testing the centuryFromYear function with various year inputs and verifying the results
        Console.WriteLine(centuryFromYear(1799) == 18); // Verifies if the century for year 1799 is 18
        Console.WriteLine(centuryFromYear(1900) == 19); // Verifies if the century for year 1900 is 19
        Console.WriteLine(centuryFromYear(1901) == 19); // Verifies if the century for year 1901 is 19
        Console.WriteLine(centuryFromYear(1901) == 20); // This line seems to have an incorrect expectation (1901 can't be both 19th and 20th century)
        Console.WriteLine(centuryFromYear(1806) == 19); // Verifies if the century for year 1806 is 19
        Console.WriteLine(centuryFromYear(1568) == 20); // Verifies if the century for year 1568 is 20
        Console.WriteLine(centuryFromYear(2010) == 21); // Verifies if the century for year 2010 is 21
    }
}

Sample Output:
