hi i m making a window application in which i want that when i enter a expanded form of a number in a textbox like (5*10000+6*1000+7*100+8*10+9*1) , then after button click it will show the answer of it like (56789).
and i also want reverse of this that when i enter a number like (56789) in textbox, then after button click it will show its expanded form like( 5*10000+6*1000+7*100+8*10+9*1 ).
First, you need to get a random number by using Random class, example:
CODE
Random random = new Random(); int number = random.Next(1, 100000);
Next, I would create a string which has the number in it:
CODE
string strNumber = number.ToString();
Parsing string is easier than number in my opinion.
Next, you get the numbers of strNumber and multiply them by "1" + requiredAmountOfZeros, something like this:
CODE
string line = ""; for (int i = 0; i < strNumber.Length; i++) { line += strNumber[i].ToString() + "*1"; for (int j = 0; j < strNumber.Length - (i + 1); j++) { line += "0"; } }
Might work but I didn't bother to test it. Testing the code and correcting the errors is your job.
thanks 4 ur rply... but i m not getting this... actully i want that first i enterd value in textbox n then on button click it will show the answer on another textbox. can u tell me the code on button click
you enter something into a textbox like 5*5*5 then it will show 125, then you type 125 and no mater what else you type every time you type 125 you want it to show you 5*5*5 cause is the stored operation for that 125?

well i m made a code for expanded form, but it will give one error error is: like i enterd a number 1234 then on button click it will give 1*1000+2*100+3*10+4*1+ here it will print one extra + how can i remove this problem
here is my code:
CODE
private void button1_Click(object sender, EventArgs e) { long x = Convert.ToInt64(textBox1.Text); string strNumber = x.ToString(); string line = ""; for (int i = 0; i < strNumber.Length; i++) { line +=strNumber[i].ToString() + "*1"; for (int j = 0; j < strNumber.Length - (i + 1); j++) { line += "0"; } line += "+"; }
this.textBox2.Text = line.ToString();
}
can anyone resolve my this problem and also tell me how can i do the reverse of this. i mean when i enter 1*1000+2*100+3*10+4*1 in one textbox, then on button click it will give its collapse form like 1234...... kindly give me code, if possible

You can remove the plus sign either with string.SubString or string.Remove methods, here is example with substring:
CODE
line = line.Substring(0, line.Length - 1);
And the easiest solution for your second problem is probably to store your variable "long x" to class scope instead of method scope, then you could show the same number easily.
CODE
private long x; private void button1_Click(object sender, EventArgs e) { // random code }
private void button_show_answer_click(object sender, EventArgs e) { // user clicked show button: show variable x TextBoxAnswer.Text = x.ToString(); }

this code has not solved my problem,kindly modify my code with another logic........

Like I wrote earlier, just a simple substring will do the trick. Here is the substring added to previous code:
CODE
private void button1_Click(object sender, EventArgs e) { long x = Convert.ToInt64(textBox1.Text); string strNumber = x.ToString(); string line = ""; for (int i = 0; i < strNumber.Length; i++) { line +=strNumber[i].ToString() + "*1"; for (int j = 0; j < strNumber.Length - (i + 1); j++) { line += "0"; } line += "+"; }
// this line here: line = line.Substring(0, line.Length - 1);
hi, jaane paane The solution which u gave me for my second problem does not work when I am making separate applications for both.... Kindly tell me how can I find numeral for expanded form ........ How can i parse the string to find the equivalent numeral
Can anyone give me the reply to solve my problem.?
Ok heres what I think you want; I made a console app to test it, but you can easily pull out the methods, and logic from it. If I didn't follow what you wanted as an end result, let me know. (Nothing based off previous, I just did both methods myself)
CODE
using System; using System.Collections.Generic; using System.Linq; using System.Text;
namespace DIC_Help { class Program { static void Main(string[] args) { Console.WriteLine("Input String"); string input = Console.ReadLine();
hi SwiftStriker00........ Can u tell me one more thing..
How can i solve mathmatical expresion(example: A+B*C-D/E, assuming A,B,C,D,E are any numbers) with the help of BODMAS rule. The main problem which i m facing is that i do not know how to parse the input string and solve it by BODMAS rule. Kindly help me regarding this......
Well, now your getting into a little bit more complicated of a subject. Your going to have to break your input into tokens (an array of individual chars). Then your going to need a little recursion and an understanding of Polish Notation (wiki has good explination). The computer works in Polish notation, and that way you do your order of operations (BODMAS/PEDMAS).
hi SwiftStriker00. i tried, but could not achieved anything............ Can u provide me the code, if possible........
That code is a bit more than a snippet. And would take considerable thought, something I shouldn't be doing at work .
But think about this. In my previous code, I broke the string up based on an operation sign, correct? Use that knowledge to start attacking the issue. You know that * and / go first so look for those so find those, and do the math on those and replace the "B*C" with your new result "F". So your next state would look like " A+F-D/E". Now keep doing this until there are no more math symbols. Btw Parentheses will complicate this process greatly, so avoid them at first, and figure out what your donig.
