I need help to write a program that includes two functions named calc_avg() and varience(). The calc_avg() function should calculate and return the average of the values stored in a static array called testvals. The array should be declared in main() and include that values 89, 95, 72, 83, 99, 54, 86, 75, 92, 73, 79, 75, 82, and 73. The varience is obtained by subtracting the average from each value in testvals, squaring the values obtained, adding them, and dividing by the number of elements in testvals. The values returned from calc_avg() and varience() should be displayed in main()???

Written for console app....
static void Main(string[] args)
{
int[] testvals = { 89, 95, 72, 83, 99, 54, 86, 75, 92, 73, 79, 75, 82, 73 };
int avg = calc_avg(testvals);
Console.WriteLine("The average value is : " + avg);
int var = calc_var(testvals);
Console.WriteLine("The variance is: " + var);
Console.ReadLine();
}
private static int calc_avg(int[] testvals)
{
int tmpSum = 0;
for(int x = 0;x<= testvals.Length - 1;x++)
tmpSum += testvals[x];
return tmpSum / testvals.Length;
}
private static int calc_var(int[] testvals)
{
int[] tmpVal = testvals;
int tmpSqr = 0;
int tmpAdd = 0;
int avg = calc_avg(testvals);
//subtract average from each value
for (int x = 0; x <= testvals.Length - 1; x++)
tmpVal[x] = testvals[x] - avg;
//square each value in tmpVal
for (int x = 0; x <= tmpVal.Length - 1; x++)
{
tmpSqr = tmpVal[x] * tmpVal[x];
tmpVal[x] = tmpSqr;
}
//Add the values up
for (int x = 0; x <= tmpVal.Length - 1; x++)
tmpAdd += tmpVal[x];
//Divide result buy number of elements in testvals
return tmpAdd / testvals.Length;
}

Congratulations!  You just did his homework for him! 
Now, he hasn't learned a damn thing and will copy and paste you code into a project, turn it in as his own work, and get a failing grade for it! I hope your proud of yourself!
On top of that, this is the VB.NET Forum, not C++ or C#.

Your right Dave I did do his homework and hopefully he will get a failing grade for it to.
The code posted was written as an example. If cut and pasted into his assignment, most likely it will not match the requirements of the assignment. As far as him learning something, it would be a lesson. A lesson that teaches not to copy someone's examples but to study them and learn from the example provided. Books do this all the time, at least the ones I read.
I do appologize for posting in the incorrect forum!
Cheers

Here's something funny. I dunno how well the code that was posted works, but he's chosen not to use it, he's asked the same question again in the C# forum.

I strongly advise you to either start doing your own homework ( and at least learn to read, this is the VB.NET forum ), or practice saying 'do you want fries with that' in front of the mirror.

Hi,
I want to create a datagrid having only single row, editable too. because I want to create a filter type application where user can specify text to filter in the grid.
The problem is whenever user write anything in the first row, second row appears automatically, which is not required.
Plz help

Sounds like you should use a textbox vs. a datagrid.

Hi,
I have this code below and I want to get the sum of the amount of the "441210" and "441110". Please show me the code. thanks.
Case "441210"
amt = Mid(strLine, 93, [20])
Range("I10").Select
Range("I10").Value = amt
Case "441110"
amt = Mid(strLine, 93, [20])
Range("J10").Select
Range("J10").Value
Range("J10").Value = amt
Thanks

You're kidding, right ?
Use Convert.ToInt32 to get ints, then use the + operator to add them.
Your code is pretty messy, if you know the values, why are you calling Mid, or is that not what this is doing ?

I use Mid function because the value is from my source which is text file and it automatically extract the data from it.

The Case blocks are separate blocks of code - in other words the case for handling "441210" does NOT drop through to case "41110". What you'll need to do as create a separate variable to hold the sum of these cases viz:
<br />
Dim totalAmt as Integer<br />
totalAmt = 0<br />
<br />
Select Case ....<br />
<br />
Case "441210"<br />
amt = Mid(strLine, 93, [20])<br />
Range("I10").Select<br />
Range("I10").Value = amt<br />
totalAmt = totalAmt + amt<br />
<br />
Case "441110"<br />
amt = Mid(strLine, 93, [20])<br />
Range("J10").Select<br />
Range("J10").Value<br />
Range("J10").Value = amt<br />
totalAmt = totalAmt + amt<br />
<br />
End Select <br />
The variable totalAmt will hold the sum of the two cases and you can then use this in your program.

Hi,
I have my source file containing numbers and link to my excel. There is some cell that the value of the number must be in negative value but in my source, it is in positive value.
Please show me the code on how to convert negative value to positive value, vise versa when it is transferred to my excel template.
More thanks.

Multiply your value by negative one, this will convert a positive to a negative and a negative to a positive.
x *= -1

Hi. Anyone knows which is the name of desktop applications that uses an embedded web ui to interact with the user, like McAfee security center, etc. Any link to a tutorial or article about that kind of applications!? 
Thanks in advance...!

Given that a web UI is limited compared to a Winforms UI, why would you do such a thing ? You can easily simulate a web UI in winforms, seeing as winforms does so much more.
The only reason I can think of to do this is to reuse the UI on the web, and then host IE in your winforms app. I still don't like it.

Perhaps you should take a look at HTA. (Search MSDN for it.)
Basically, it allows you to run an HTML file (with embedded java/VB script) just like an app. But like Christian said, it is a more limitted user interface.
