[RESOLVED] [1.0/1.1] Loop problem?

I only started C# today (i already know VBNET), and can't work out whats wrong with this loop:

Code:

---

                static void Main(string[] args)
                {
                int[] i = new int[3];


                i[0] = 2;
                i[1] = 4;
                i[2] = 61;

                int sum;

                for (int x = 0; x < 2; x++)
                {

                        sum += i[x];
                }

                Console.WriteLine(sum);
                Console.ReadLine();
                }

Sorry for such a simple question.

Wait....i know. x doesn't have a value yet, so it can't be used.

It's not 'x' that's the issue. It's 'sum'. You need to initialise all variables in C#.

Code:

---

int sum = 0;

---

This is one of the ways in which C# is stricter than VB.NET. If you want 'sum' to be zero then you have to specify it. That way you actually have to think about what value you want a variable to have and you won't simply forget to set a value and have a variable default to zero when that isn't what you want.

Thats what i meant :D.
