Question

Need help writing beginner C# program, I will make sure to provide feedback to whoever can help me figure it out!

No public or global variables should be used. You need to consider passing arguments between the methods according to the ways described in the lecture. i.e. all variables should be declared inside the methods and passed to other methods by value/ref/out as needed
Description: We want to design a Date class to represent a date using three integer numbers for day, month, and year. Our class will be named tDate. The class has two static attributes (earliestDate, latestDate) to represent the earliest and latest dates it can hold. These static attributes are strings contain dates formatted as "mm/dd/yyyy" (using US date formatting). The class can be instantiated in two ways, the first is using three integer arguments separated by comma as (mm, dd, yyyy), and the second is using string contains a date formatted as "mm/dd/yyyy". Each object of this class type can show its date formatted as either (US) mm/dd/yyyy or (Europe) dd/mm/yyyy according to an argument passed to its showDate( ) method. Write C# program that implements the date class described above according to the following: 1. Declare the class named tDate with the appropriate private static and non-static attributes, public constructors, and public methods. Make this class in a separate .cs file 2. The class constructors must parse the passed arguments correctly and do the following verification(s) before initializing the attributes (day,month,year) of the created object: -Verify that the arguments it received form a valid date (do just simple verification, like, 0< days<=31, 0 <months <=12, year >0). i.e. using (15,18,2010) as valid date because the month >12. Similarly, "15/18/2010" is not valid too. not be accepted If the verification failed, the constructor should initialize the attributes (day, month, year) of the new object using the "earliestDate" date values. Hint: The "earliestDate" attribute is a string, so you need to parse it to extract its day, month and year components using string split() method. 3. The showDate method should receive an argument to specify which format the method should use to display the date (US or Europe), then prints the date according to the given format. The argument could be char ('U' for US, 'E' for Europe) or int (0 for US, 1 for Europe) or a string. 4. The main program method main( ) should do the following : a) Set the static attributes (earliestDate, latestDate) of the tDate class as "1/1/1900", and "12/31/2100" respectively. b) instantiate the following objects as follows : 1- dl using three integer values (12,15, 1990) 2- d2 using the string ("12/15/1990") 3- d3 using the string ("15/12/1990"), which is invalid date 4- d4 using the string ("11/11/1811"), which is out of range date (CIDM5360 programmers code shouldn't accept this as valid date)

Solution:

TDate.cs:

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

namespace ConsoleApp2
{
class TDate
{
private static string earliestDate = "1/1/1900";
private static string latestDate = "12/31/2100";
private int day, month, year;
TDate(string date)
{
string[] objectDate = date.Split('/');
string[] earliest = earliestDate.Split('/');
if (int.Parse(objectDate[0]) > 0 && int.Parse(objectDate[0]) <= 31)
{
day = int.Parse(objectDate[0]);
} else
{
day = int.Parse(earliest[0]);
}
if (int.Parse(objectDate[1]) > 0 && int.Parse(objectDate[1]) <= 12)
{
month = int.Parse(objectDate[1]);

} else
{
month = int.Parse(earliest[1]);
}
if (int.Parse(objectDate[2]) > 0)
{
year = int.Parse(objectDate[2]);
} else
{
year = int.Parse(earliest[2]);
}
}

public void showDate(Char c)
{
if(c == 'U')
{
Console.WriteLine("US Date: " + day + "/" + month + "/" + year);
} else
{
Console.WriteLine("European Date: " + month + "/" + day + "/" + year);
}
}
static void Main(string[] args)
{
TDate d1 = new TDate("12/15/1990");
d1.showDate('U');
d1.showDate('E');
TDate d2 = new TDate("15/12/1990");
d2.showDate('U');
d2.showDate('E');
TDate d3 = new TDate("11/11/1811");
d3.showDate('U');
d3.showDate('E');
Console.ReadLine();
}
}
}
Output:
