ya hallo, so basically im making a code where the console prints out the current date and timing as the date and timing of birth

using System;

class Contact.cs
{
    private int = (firstName);
    private int = (lastName);
    private int = (dateOfBirth);
    
    {
        Contact c = new Contact();
        System.Console.WriteLine(c.ToString());
    }
}

public override string ToString()
{
    StringBuilder stringBuilder = new StringBuilder
    stringBuilder.AppendFormat("Name:{0} {1}/r/n",this.firstName);
    stringBuilder.AppendFormat("Date of birth;{0} {1}/r/n",this.dateOfBirth);
    
}

and so the error is this

/tmp/ttMvToF0Y4.cs(3,14): error CS1514: { expected
/tmp/ttMvToF0Y4.cs(3,14): error CS1513: } expected

Hi @Mohammad-Riyaz2 !
What language is this in?

I’m just guessing it’s CSharp based on everywhere it says “cs”

sorry for the late reply, the language is in c#

Hey @Mohammad-Riyaz2!

It looks like you have provided incomplete and somewhat incorrect code. I’ll help you fix it and explain the changes I’ve made:

using System;
using System.Text;

class Contact
{
    private string firstName; // Use 'string' for name fields
    private string lastName;  // Use 'string' for name fields
    private DateTime dateOfBirth; // Use 'DateTime' for date fields

    // Constructor
    public Contact(string firstName, string lastName, DateTime dateOfBirth)
    {
        this.firstName = firstName;
        this.lastName = lastName;
        this.dateOfBirth = dateOfBirth;
    }

    public override string ToString()
    {
        StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.AppendFormat("Name: {0} {1}\r\n", this.firstName, this.lastName);
        stringBuilder.AppendFormat("Date of Birth: {0}\r\n", this.dateOfBirth.ToString("yyyy-MM-dd"));
        return stringBuilder.ToString();
    }

    // Entry point of the program
    static void Main(string[] args)
    {
        Contact c = new Contact("John", "Doe", new DateTime(1990, 1, 15));
        Console.WriteLine(c.ToString());
    }
}

Here’s what I’ve changed and why:

  1. Fixed field declarations:

    • You should use the string data type for the firstName and lastName fields, as they store names.
    • The dateOfBirth field should use the DateTime data type to store dates.

  2. Added a constructor:

    • I added a constructor that accepts values for firstName, lastName, and dateOfBirth to initialize the fields when a Contact object is created.

  3. Fixed the ToString() method:

    • I corrected the format specifiers in the AppendFormat calls within the ToString() method.
    • I added a ToString("yyyy-MM-dd") call on the dateOfBirth field to format the date appropriately.

  4. Added the return statement in the ToString() method to actually return the formatted string.

  5. Moved the entry point (Main method) into the Contact class for clarity.

With these changes, the code should now work as intended, creating a Contact object, formatting its details, and printing them to the console.

I would just change this:

    // Entry point of the program
    static void Main(string[] args)
    {
        Contact c = new Contact("John", "Doe", new DateTime(1990, 1, 15));
        Console.WriteLine(c.ToString());
    }
}

To this:

class Program
{
    static void Main()
    {
        Contact c = new Contact("John", "Doe", DateTime.Now);
        Console.WriteLine(c.ToString());
    }
}

To avoid hard-coding DateTime.

Also, as for the main method:

  • If your program needs to accept command-line arguments, then use static void Main(string[] args).
  • If your program does not need to accept command-line arguments, then you can use static void Main().
