C# For Loop

[chkmte21]

Hi, my problem is displaying the sequence of a for loop in a label. I am sure this is simple, but cannot figure it out. Please help... I want the dice to roll 100 times, and each time there is a double, it will display the roll sequence (the 2nd roll) thanks. Below is my code segment

private void button1_Click(object sender, EventArgs e)
{
Random rollDie = new Random();
int i, die1, die2, die1Value, die2Value, doubles;

int count = 100;
for (i = 1; i <= count; i++)
{
label3.Text = "";
label4.Text = "";

die1 = rollDie.Next(6);
die2 = rollDie.Next(6);

die1Value = die1 + 1;
die2Value = die2 + 1;

lblDie1.ImageIndex = die1;
lblDie2.ImageIndex = die2;



if (die1 == die2)
{
label3.Text = "you rolled double " + "'s";
label4.Text = ("Current value of i is " + i);

}



}

**Update** Please help if you can. the label is saying the roll sequence is 100 everytime i roll doubles...

private void button1_Click(object sender, EventArgs e)
{
Random rollDie = new Random();
int i, die1, die2, die1Value, die2Value, doubles;

int count = 100;
for (i = 1; i <= count; i++)
{
label3.Text = "";
label4.Text = "";

die1 = rollDie.Next(6);
die2 = rollDie.Next(6);

die1Value = die1 + 1;
die2Value = die2 + 1;

lblDie1.ImageIndex = die1;
lblDie2.ImageIndex = die2;

doubles = die1 + 1;


if (die1 == die2)
{
label3.Text = "You rolled double " + doubles + "'s";
label4.Text = ("On the " + i + "th roll");
}


}


}

}

}

You won't see the display until the function exits.
Using the debugger, I saw that the dies matched 16 times. Of course, each time the results may vary. If you execute label3.Text = ""; and label4.Text = "";, you may see blank for those labels unless you got a match right before the function exited. You may want to add each update to the label string, otherwise you will only display the last match.

I took out the blank label.text execution, and it seemed to help. What function are you referring to? How do I do each update? Sorry, I am a novice C# programmer... Thank you for your help

Its displaying when I get doubles, but doesn't show the sequence in the iteration when the doubles occurred. It just says 100th roll instead of the correct sequence

[Jim_Auricman]

The function is: private void button1_Click(object sender, EventArgs e)
Outside the 'for' loop, add: label4.Text = "Value of i where there was a match, is ";
Then inside the place where "if (die1 == die2)" add: label4.Text += ", " +i;
That way after the function exits, all the places "i" where there was a match, are displayed.

Thank you for your response, but I am still having trouble. Every time I click the button "roll dice", it should roll the dice as a sequence starting with 1 and go to 100 each time its clicked. It looks like it runs all the way to 100 and shows the first or last matching double. I am so confused. I think their should be a break or continue in the loop, like a pause. Am I in the right direction? How would you do this. Thanks for any help

RESOLVED!! Used a counter instead of loop...

[Jim_Auricman]

I usually prefer 'while' loops that exit when a flag is set, indicating that certain conditions have been met. For example,

while(!done)
{
// do whatever needs to be done;
// When condition(s) have been met, 
done - true;
}

I only use 'for' loops when a specific number of loops need to be made without premature exit.
