  7.         static private int numeroemp = 0;

  25.             Console.WriteLine("Numero de empleados creados {0} ", Empleados.obtenernumeEmpledos() );
  26.         }
  27.  
  28.         static void Main(string[] args)
  29.         {
  30.  
  31.               int edad = 46;
  32.  
  33.      Empleados emp1 = new Empleados (edad);
  34.      emp1.mostrarInfo();
  35.      Empleados emp2 = new Empleados(45);
  36.      emp2.mostrarInfo();
  37.  
  38.  
  39.  
  40.  
  41.         }
  42.  
  43.         public static int obtenernumeEmpledos()
  44.         {
  45.  
  46.             return numeroemp;
  47.         }
  48.     }
  49. }

this mi question if I run this program the results are

el empleado 1 tiene 46 años
numero de empleados creados 1
el empleado 2 tiene 45 años
numero de empleados creados 2

its ok but if i change
this code

C# Syntax (Toggle Plain Text) 
  1.   public Empleados(int edad)
  2.         {
  3.  
  4.             this.edad = edad;
  5.             Empleados.numeroemp   ++;
  6.  
  7.  
  8.  
  9.         }
for this

C# Syntax (Toggle Plain Text) 
  1.   public Empleados(int edad)
  2.         {
  3.  
  4.             this.edad = edad;
  5.             Empleados.numeroemp  = + 1;
  6.  
  7.  
  8.  
  9.         }

the results are

el empleado 1 tiene 46 años
numero de empleados creados 1
el empleado 2 tiene 45 años
numero de empleados creados 1

why??

is no the same using ++ than + 1???
or i am wrong??

in your case it doesn't matter, which way you use to add 1. I suppose that you was talking about "+=" operator?
Let's see:
1.
c# Syntax (Toggle Plain Text) 
  1. Empleados.numeroemp++;
increasing numeroemp by 1.
2.
c# Syntax (Toggle Plain Text) 
  1. Empleados.numeroemp += 1;
which is the short version of this:
c# Syntax (Toggle Plain Text) 
  1. Empleados.numeroemp = Empleados.numeroemp + 1;
3.
c# Syntax (Toggle Plain Text) 
  1. Empleados.numeroemp  = + 1;
here you assign numeroemp by +1.
So what if you can see the darkest side of me?

The difference is the

= +1
is the same as =1
where as

+= 1

will add one and store it.

Did I just hear "You gotta help us, Doc. We've tried nothin' and we're all out of ideas" ? Is this you? Dont let this be you! I will put in as much effort as you seem to.
