I am really sorry but I am having hard time understanding this. Can you explain little bit more, how compiler does it by itself.

I have these codes.

Console.Writeline("i = {0\t obj = {1}", i ,obj);
obj *=2;

Okay got it thanks.

Quick question. outputs:
Baby is called: kitten
Baby is called: puppy
Is because of the foreach loop correct?

Thank you. There was a printing error in the book "! =" and error from my side "b.Babycalled."

namespace Interfaces
{
interface IInfo
{
string GetName();
string GetAge();
}
class CA : IInfo
{
public string Name;
public int Age;
public string GetName() { return Name; }
public string GetAge() { return Age.ToString(); }
}
class CB : IInfo
{
public string First;
public string Last;
public double PersonsAge;
public string GetName() { return First + " " + Last; }
public string GetAge() { return PersonsAge.ToString(); }
}
class Program
{
static void PrintInfo(IInfo item)
{
Console.WriteLine("Name: {0}, Age {1}", item.GetName(), item.GetAge());
}
static void Main()
{
CA a = new CA() { Name = "John Doe", Age = 35 };
CB b = new CB() { First = "Jane", Last = "Doe", PersonsAge = 33 };
PrintInfo(a);
PrintInfo(b);
}
}
}

I was looking at the following codes below and trying to do the same with the above informations

Thank you Sergey for confirming the codes. And your past answers are also very helpful.

Thank you Peter. That makes a whole lot of sense than reading the same example over and over again in the book.

That's the one exactly from the book. If you have any good books in mind please let me know.

Thank you so much. I think I got it this time. Wouldn't be possible without your help though. You are awesome.

{ class Magic
{
private int spiders;
public int Spiders
{
set
{spiders = value;
}
get
{return spiders;
}
}

private int toads;
public int Toads
{
set
{toads = value;
}
get
{return toads;
}
}
public void do_myMagic()
{
Console.WriteLine("Pooofff");
}
public Magic()
{

}
public Magic(int arg1, int arg2)
{
toads = arg1;
spiders = arg2;
}
class Program
{
static void Main()
{
Magic myMagic = new Magic(3,5);

myMagic.do_myMagic();
}
}
}
}

With your help, so far I have come up with following codes. Still not getting completely what I am missing.

I am taking intermediate programming C#. It is a four year college and this is my second class in programming. Not only I, most of the students in my class having same problem. Not understanding the concept pretty well. Anyway, thank you for the sending those resources. I really appreciate that.

Thank you for your help. You are right I have very little knowledge on constructors, in fact very little knowledge. I will definitely read on constructors and try to complete this.

Can you refer me to a good C# programming book?

My instructor has a C++ background, he recently studied C# and this is his second semester. He himself is confused while teaching. Whatever I have learned, I used youtube and all other online resources. I even don't know what the above program was asking and what would be its output.

Got it thanks. I was thinking, I declared the "sum" as double, therefore the output of sum will also be in decimals.

Got it. Thank you so much for your help. It helped me clear lot of confusion I was having.

I got these two error messages when I move trihypo to function.
Error 1 The name 'trihypotenuse' does not exist in the current context C:\Users\Bibek\Desktop\Winter classes 2013\Introduction to Programing C#\Assignments\ProjectFive\ProjectFiveOne\ProjectFiveOne\Program.cs 16 63 ProjectFiveOne

Error 2 A local variable named 'trihypotenuse' cannot be declared in this scope because it would give a different meaning to 'trihypotenuse', which is already used in a 'parent or current' scope to denote something else C:\Users\Bibek\Desktop\Winter classes 2013\Introduction to Programing C#\Assignments\ProjectFive\ProjectFiveOne\ProjectFiveOne\Program.cs 27 20 ProjectFiveOne

{ class Program
{
static void Main(string[] args)
{
double tribase = 6;
double triwidth = 9;
double triarea = triArea(tribase, triwidth);
double triperimeter = triPerimeter(tribase, triwidth, trihypotenuse);
Console.WriteLine("Area of right triangle = {0}\nPerimeter of rigth triangle = {1}\n", triarea, triperimeter);

double squareside = 8;
double squarearea = GetSquareArea(squareside);
double squareperimeter = GetSquarePerimeter (4 * squareside);
Console.WriteLine("Area of square = {0}\nPerimeter of square = {1}\n", squarearea, squareperimeter);
}

private static double triPerimeter(double tribase, double triwidth, double trihypotenuse)
{
double trihypotenuse = Math.Sqrt((tribase * tribase) + (triwidth * triwidth));
double triperimeter = tribase + triwidth + trihypotenuse;
return triperimeter;
}

private static double triArea(double tribase, double triwidth)
{
double triarea = 0.5 * (tribase * triwidth);
return triarea;
}

static double GetSquareArea(double squareside)
{
double squarearea = squareside * squareside;
return squarearea;
}
static double GetSquarePerimeter(double squareside)
{
double squareperimeter = 4 * squareside;
return squareperimeter;

}


}

Thank you so much.

Yes, I am using visual studio 2013 express for desktop.

Yes, it was one of my homework question, it is now 3 weeks past due, got only half a point. Professor told me to use any resource and get it right and she will give me couple of extra points. So far I have got following:

static double GetSquareArea(double squareside)
{
double squarearea = squareside * squareside;
return squarearea;
}
static double GetSquarePerimeter(double squareside)
{
double squareperimeter = 4 * squareside;
return squareperimeter;

}
No idea how to do perimeter and area of right triangle in different functions.
