C# 2005

ADAM89 · 1 Apr 2011 at 16:58

Hi all, I'm still very new to C#, and right now I have a project, where I am creating a program.

What I need to do is declare three arrays namely A1, A2, and A3 each of size k.
Assign random values to array A1.
I want to write a C# program in microsoft visual studio 2005 using arrays and function to implement the following:
A2 (0) = A1 (k), A2 (1) = A1 (k-1), and so on….

A3 (k) = A1(k) if A1(k)>A2(k),

= A2 (k) otherwise
Output all the elements of arrays A1, A2 and A3

Please if you could help me, would be much appreciated.

Many thanks

Adam

What have you got so far?

We're usually not happy to do other's coursework for them, but happy to help with a particular problem you are stuck on.

Just get started, and tweak until it works. Step through the code with F11 and use the Local Watch window to see what's going on at each step.

Ok thank you for the response.

If someone could give me a starting point would be much appreciated.

How far have you got?

Starting from the start you'll need to create a new project. A command line app would be ideal for this as you don't need to worry about creating a UI.

Check out this guide: http://msdn.microsoft.com/en-us/library/0wc2kk78(v=vs.90).aspx
It's for VS 2008, but the principles are the same.

Has your lecturer not given you any materials or a guide to work with?

No materials provided thats why im a bit lost on what to do and how to start. Thanks for the input very much appreciated!

I managed to get this, if someone could let me know if what iv done is right pls it would much help.

static void Main(string[] args)
{
const int k = 10;

int[] A1 = new int[k];
int[] A2 = new int[k];
int[] A3 = new int[k];

for (int i = 0; i < k; i++)
{
A1 = i + 1;
}

for (int i = 0; i < k; i++)
{
A2 = A1[k-1-i];
}

for (int i = 0; i < k; i++)
{
A3 = (A1 > A2) ? A1 : A2;
}

for (int i = 0; i < k; i++)
{
Console.WriteLine("A1[" + i + "] = " + A1);
Console.WriteLine("A2[" + i + "] = " + A2);
Console.WriteLine("A3[" + i + "] = " + A3);
Console.WriteLine("");
}
}
}
}

Can't test it at the mo, but from the looks of it you should be able to put it all into one loop which should speed up the process:

Code:

static void Main(string[] args) {
	const int k = 10;

	int[] A1 = new int[k];
	int[] A2 = new int[k];
	int[] A3 = new int[k];

	for (int i = 0; i < k; i++) {
		A1[i] = i + 1;
		
		A2[i] = A1[k-1-i];
		
		A3[i] = (A1[i] > A2[i]) ? A1[i] : A2[i];
		
		Console.WriteLine("A1[" + i + "] = " + A1[i]);
		Console.WriteLine("A2[" + i + "] = " + A2[i]);
		Console.WriteLine("A3[" + i + "] = " + A3[i]);
		Console.WriteLine("");
	}
}

Sorry so the code I implemented is correct for the program?

IMpossible to tell because your description doesn't make sense.
