I just started C# and I've been stuck on this for over an hour. So I'm trying to make a program to calculate age and this is the code I thought would work:

using System;
using System.Collections.Generic;

namespace Project1
{
     class Program
     {
          static void Main(string[] args)
          {
               int x, y, age;

               Console.Write("Current year = ");
               x = int.Parse(Console.ReadLine());
    
               Console.Write("Your birth date = ");
               y = int.Parse(Console.ReadLine());
    
               age = x - y
               Console.Write("Your are "   age   "  years old!");
               Console.ReadKey();
          }
     }
}

I expected to see something like this in the console:

Current year = 2023 Your birth date = 2004 You are 19 years old!

But instead I get an error each time and it highlights the lines of code in which I tried to assign x & y, it also underlined Consol.ReadLine()

IDE: Microsoft Visual Studio

All syntax errors corrected:

using System; // u instead of U
using System.Collections.Generic; // u instead of U

namespace Project1 // n instead of N
{
class Program // c instead of C
{
static void Main(string[] args)
{
     {
          {
               int x, y, age;

               Console.Write("Current year = "); // missed `;`
               x = int.Parse(Console.ReadLine());
    
               Console.Write("Your birth date = "); // missed `.`
               y = int.Parse(Console.ReadLine());
    
               age = x - y; // missed `;`
               Console.Write("Your are "   age   "  years old!"); // missed `"` and `;`
               Console.ReadKey();
          }
     }
}
} // missed `}`
} // missed `}`

Please, remember:

• It is you who reads the program first, format it
• VS is your friend, it provides hints what is wrong with the syntax

Let's improve your code, it can be something like this:

using System; 

namespace Project1 {
  class AgeComputing {
    static void Main(string[] args) {
      Console.Write("Current year = "); 
      int currentYear = int.Parse(Console.ReadLine());
    
      Console.Write("Your birth date = "); 
      int birthYear = int.Parse(Console.ReadLine());
    
      int age = currentYear - birthYear;
        
      Console.Write($"Your are {age} years old!"); 
        
      Console.ReadKey();
    }
  }
}
