I suggest that you read on how to ask a good question first Straight from Separation of concerns: design principle for separating a computer program into distinct sections, such that each section addresses a separate concern. I hope that you are not the developer taking over this project, because it seems like you have minimal … Read more
On your system, long is 32 bits. The largest positive integer it can hold is 4294967295. But 1836311903 + 2971215073 = 4807526976, which is larger, so it overflowed and you got 512559680 (which is 4807526976 – 4294967296). If you want to go past the 47th Fibonacci number, you’ll need a larger datatype or do multi-precision … Read more
It’s unclear what the problem is but your for loop doesnt over the letters in word as the termination condition is based on the empty List size passed to the buildAL method. Replace for (int i = 0; i < arr2.size(); i++) with for (int i = 0; i < word.length(); i++) { solved Error … Read more
A solution: Scanner input = new Scanner(System.in); int l; // it should be int if read int l = input.nextInt(); if (l <= 30) { System.out.println(“40 Sinas”); } if (l > 30 && l < 50) { System.out.println(“55 Sinas”); } if (l > 50 && l < 100) { System.out.println(“70 Sinas”); } if (l >= … Read more
First, there appears to be a typo in your question. Apparently your formula isn’t A^2-B^2=(A-B)+(A+B), as the beginning of your question suggests; the example shown is doing multiplication on the right-hand side of the equation. Here’s a very basic example of how to do this. int a = ReadInt(“Enter value for A: “); // see … Read more
You need to split it up into sections. First: Get positive number double i; double k; Console.Write(“What is your total income : “); while (!double.TryParse(Console.ReadLine(), out i) || i < 0) { if (i < 0) { Console.WriteLine(“Your income cannot be negative.”); } else { Console.WriteLine(“Enter your income as a whole-dollar numeric figure.”); } } … Read more
Assuming you don’t care what the file names are, you could write each batch of messages to a new temp file, thus: import tempfile texts = some_function_grabbing_text() while texts: with tempfile.TemporaryFile() as fp: fp.write(texts) texts = some_function_grabbing_text() solved How to save data in multiple files on python
A watchdog is a mechanism that periodically tests whether a process or thread is running properly. If it’s not, it either restarts it or notifies an administrator, depending on the needs of the application. The details of how you implement this will depend on the application design. solved What is a watchdog? [closed]
I would prefer i++ over the other two because it expresses a common idiom. Those lines of code all end up doing exactly the same thing. But if I’m scanning code for an increment, the ++ just sort of jumps off the page. Also, the i = i++ is actually incorrect. You meant i = … Read more
You can use row_number() and conditional aggregation. Here is an exaple: select customerid, avg(sales) as avgsales, max(case when segnum = 1 then sales end) as sales_01, max(case when segnum = 2 then sales end) as sales_02, max(case when segnum = 3 then sales end) as sales_03 from (select t.*, row_number() over (partition by customerid order … Read more
Here is an example (completely neglecting error handling): request, _ := http.Get(“https://api.github.com/repos/openebs/openebs”) defer request.Body.Close() bytes, _ := ioutil.ReadAll(request.Body) var apiResponse struct { StargazersCount int `json:”stargazers_count”` } json.Unmarshal(bytes, &apiResponse) fmt.Println(apiResponse.StargazersCount) Playground 3 solved How to extract json api through go to extract stargazers_count of a repo?
Based on the example you provided, it seems to me that you want to repeatedly add the same elements (plural) into your array a particular N number of times. Because arrays are fixed in size, you can’t declare int[] a1 = {1,2,3};and then attempt to add more elements to it. That is why I recommend … Read more
Here are a few hints foldAEB2 Nil Un Conc is the identity function foldAEB2 Nil Un Conc :: AEB2 a -> AEB2 a Un :: a -> AEB2 a \a -> Conc (Un a) (Un a) :: a -> AEB2 a 4 solved Function double in haskell
This should work: OleDbCommand cmd = new OleDbCommand(@”INSERT INTO tbbill(invoice,[datetime],custm,total,tax,grand) VALUES(” + Convert.ToInt32(txtinvoice.Text) + “,\”” + dateTimePicker1.Value.ToString(“yyyy/MMM/dd”) + “\”,\”” + Convert.ToString(txtcn.Text) + “\”,\”” + txtttl.Text + “\”,\”” + Convert.ToInt32(cmtax.Text) + “\”,\”” + txtgrdttl.Text + “\”)”, con); cmd.CommandType = CommandType.Text; cmd.ExecuteNonQuery(); con.Close(); EDIT: As stated by others, your query is still open to SQL injection.

Yes, you will need to put your file inside the libraries folder(if the class is separate from codeigniter or is shared among many controllers, if not a Model would suffice), then create a controller for it. class Ajax_Controller extends CI_Controller { public $statusCode = 200; public $response = array(); public function __construct() { parent::__construct(); if(!$this->is_ajax_request()){ … Read more
