I'm new to c#, and I'm kinda struggling with implementing interfaces, gonna be very grateful if someone helps me with this, with an explanation. Thanks
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace interfejsi
interface Figura
{
String Plostina ();
String Perimeter ();
}
}
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace interfejsi
{
class Kvadar : Figura
{
int a,b,c;
public String Perimetar(int a, int b, int c)
{
return (a + b + c).ToString();
}
public String Plostina(int a, int b, int c)
{
return (a * b * c).ToString();
}
}
}
You need to implement the exact functions that sit in the interface(with the same number of input params)..
So in you case change your interface to:
interface Figura
{
String Perimetar(int a, int b, int c)
String Plostina(int a, int b, int c)
}
Or change you implementation to functions with no params.
