Does anyone know a logic to divide a number randomly? I need to do this in C#, but it might just be logic here.
Example:
I want to split 10 = 3 + 4 + 1 + 2
I want to split 30 = 2 + 5 + 8 + 4 + 6 + 5
Pseudo Code:
myNumber = 30; //Number to split
int maximumValue = myNumber; //Maximum value we can get with rand()
int totalValue = 0; //Save our total
while(totalValue < myNUmber)
{
newSplitNumber = rand(0, maximumValue); //Use as needed
totalValue+= newSplitNumber; //Update our total
maximumValue = myNumber - totalValue; //Update our maximum on next iteration
}

In the below code i have declared an and then assigned it to z. [Please note this is a duplicate]
double an;
for(double z= Amt+Intrest; z>0; z-=MonthlyInstallment)
{
an = z;
}
I want to access the an variable in the below loop.
for (int i = 0; i < Months; i++)
{
dt.Rows.Add(i + 1, MonthlyInstallment, MonthlyIntrest, MonthlyInstallment - MonthlyIntrest,//use the an variable here);
}
You cannot relate the two loops directly, because I assume that those have equal iterations.
A suggestion: You could calculate the value a the loop.
// start with the base value.
double an = Amt + Intrest;
for (int i = 0; i < Months; i++)
{
dt.Rows.Add(i + 1, MonthlyInstallment, MonthlyIntrest, MonthlyInstallment -MonthlyIntrest, an);
// decrease an with the MonthlyInstallment
an = an - MonthlyInstallment;
}

I'm working on windows form application and I have homework to calculate the square of 5 numbers in one textbox and I have to put all 5 numbers in different lines
I expect the results to be like this,
you enter 5 numbers in each line
4
9
16
25
and get them in one single message box saying the results like
2, 3, 4, 5
Pass the Textbox Text into the function and It will Print all the SqureRoot of the Numbers
private void squreRootFinder(string textBox)
{
string[] numbers = textBox.Split('\n');
string data = "";
for (int i = 0; i < numbers.Length; i++)
{
data += Math.Sqrt(Convert.ToInt32(numbers[i])) + " ";
}
MessageBox.Show(data);
}

double cash;
private void btnHesapla_Click(object sender, EventArgs e)
{
int number= Convert.ToInt32(tbadet.Text);
int oneprice= Convert.ToInt32(tbbirim.Text);
cash= number * oneprice;
if (number >= 100)
{
double i = 0;
i =cash- (cash * (5 / 100));
lblcash.Text = cash.ToString() + " $" + (" Discount");
}else
lblcash.Text = cash.ToString() + " $";
}
If the customer is over 100, they will get 5% off
but without a discount calculate
You assign final result to i variable but you use cash variable to show result.
Also, as #Bathsheba said (5 / 100) results to 0 because this operation uses two integers.
Replace this line:
i = cash - (cash * (5 / 100));
by this:
cash -= cash * 5 / 100;
You should assign to cash variable.
5 / 100 is an expression equal to 0 due to integer division.
Removing the parentheses will fix this one, and don't forget to assign to cash, rather than i which you can remove.
cash *= 0.95 is probably clearer.

I want an auto-numbering class in c# which would generate numbers of 8 digit length in the following format i.e. 1A2B3C4D..one number followed by one letter.Any suggestions??
Pseudocode for generating such string:
String result = "";
for ( int i = 0; i < 8 ; i++)
{
if ( i % 2 == 0)
{
// random(a,b) returns random value between or equal to a-b
result.append(random(0,9).toString());
}
else
{
result.append(random(65,90).toChar()); // Generating a random value between 65-90 (A-Z in ascii)
}
}
Edit:
Or as Sayse suggested:
String result = "";
for (int i = 0; i< 4; i++)
{
result.append(random(0,9).toString());
result.append(random(65-90).toChar());
}

I want to multiply two numbers one by one until last row in datagridview; and add them in a double variable .
They then divided by the total units do.
For example:
mark |units |result
12.00 * 2 = 24.00
20.00 * 3 = 60.00
15.00 * 1 = 15.00
24 + 60 + 15 = 59
59 / 2 + 3 + 1
= 59 /6
= 16.50
so show in a textbox.
for (int i = 0; i < dataGridView1.RowCount ; i++)
{<br>
mark = Convert.ToInt32(dataGridView1.Rows[i].Cells[3].Value);<br>
unit = Convert.ToInt32(dataGridView1.Rows[i].Cells[2].Value);<br>
sumunit += unit;<br>
result += ( mark * unit);<br>
}<br>
result /= sumunit;<br>
label2.Text = result.ToString();<br>
}<br>
Do not do it in DataGrid, but do it directly in the data you bind to.
Ad new row were result of computation are stored, and after bind it to DataGrid.
