Working with functions

Calling functions in C#

//You can only call functions with the same declared type without instantiating an object of the class.

public void Test1(){
    Console.WriteLine("Ist Function and Other Function "+Test());
  }
  
  public int Test(){
    return 2;
  }
  
  public static string Test2(){
    return "2nd Function";
  }
  
  public int Test3(){
    return Test();
  }
  public static void Main()
  {
    Program pr = new Program();
    pr.Test1();
    Program2 p2 = new Program2();
    p2.Abi();
    Console.WriteLine("Hello, I am main");
    Console.WriteLine(Test2());
    Console.WriteLine(pr.Test3());

  }
