[ad_1] I wonder what can I do to increase the speed of the code. Can I get rid of some loops etc? The time complexity of each test case will be O(n) regardless of what you do, since you have to read all the numbers before you know when you stop printing zeros. Now, as … Read more
[ad_1] You want to work from the highest coin you have to the lowest. How many 2s in “giveback”? Take 2* that number off giveback, then calculate how many 1s are left in “giveback”. Then how many 0.5s, and so on until the end. For example: Giveback = 8.57 4 * 2 euro coins in … Read more
[ad_1] You have a local variable of type Entry, which is automatically destroyed at the end of the function. When it is destroyed, destructors run for each of its subobjects. Probably entry.m_value = value; is copying something, and the extra copy needs to be cleaned up. 2 [ad_2] solved Why is the destructor called when … Read more
[ad_1] Thank U guys ,with all Your help I solved it private void button2_Click(object sender, EventArgs e) { button2.Text = “SAVE”; var files = Directory.GetFiles(@”C:\\Users\\Apple\\Desktop\\proj”).Length; string fileName = textBox1.Text.Substring(0, 3) + -+ ++files + “.txt”; string path2 = Path.GetFullPath(“C:\\Users\\Apple\\Desktop\\proj”); string docPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop); string var = Path.Combine(docPath, path2); string var1 = Path.Combine(var, fileName); using (StreamWriter … Read more
[ad_1] Your two options are 1) Make them member variables 2) Add them as arguments to the print() function, as shown below, then call print within the constructor (if that is the intention) void CPOI::print(string name, double latitude , double longitude) If you pass them to the constructor, but they are not stored in member … Read more
[ad_1] For many reasons – code maintainability, extensibility, concision, reliability, minimising the amount of code that needs to be recompiled/redistributed to pick up changes in some library code it uses – you should almost always use virtual functions rather that writing your own switching mechanisms. If you need to ask about it on stackoverflow, I’d … Read more
[ad_1] You can get the date and month values for start date and the year value for end date and use it to set current start date: DateTime startDate = (Convert.ToDateTime(“02/02/2016”)); var dy = startDate.Day; var mn = startDate.Month; DateTime endDate = (Convert.ToDateTime(“18/04/2018”)); var yy = endDate.Year; var currentStartDate = new DateTime(yy, mn, dy); 3 … Read more
[ad_1] You don’t need to use a GtkTreeIter for this, the GtkTreePath API is enough. You’re throwing your path away before using it, which creates problems. Here’s how to do it: GtkTreePath *path = gtk_tree_path_new_from_indices(3, -1); gtk_tree_selection_select_path(treeview_selection, path); gtk_tree_path_free(path); UPDATE: I rewrote the code completely to drop use of GtkTreeIter, I originally thought that you … Read more
[ad_1] Try This: public class Help : ModuleBase<SocketCommandContext> { [Command(“test”)] public async Task TestAsync() { await Context.Client.SetGameAsync(“eating doritos”); await Task.CompletedTask; } } [ad_2] solved Discord bot playing status
[ad_1] Preprocessor directives are interpreted before compiling your program. So VAR has no knowledge of a and b. See C preprocessor on Wikipedia. Instead, you could create a macro that takes parameters, like this: #define VAR(a,b) (a | b) …and use it like that: #if (VAR(a,b) != 0) You would have to adapt your program, … Read more
[ad_1] You can try ^\+?[0-9-]+$ See it here on Regexr The important parts are the anchors ^ and $ for the start and the end of the string. I added also \+? at the start, to match an optional +. The + needs to be escaped since it is a special character in regex, the … Read more
[ad_1] You need to use this i.e. change savings.pin = pin; to this->pin = pin; 1 [ad_2] solved expected unqualified id before “.” token
[ad_1] It should be noted that I’m only guessing about what happens here… My guess is that j becomes equal to j2 inside the loop, by one of the assignments. But then the increase j += inc happens and j is no longer equal to j2 when the loop condition is checked. Generally speaking, a … Read more
[ad_1] This works – although I’d set the thread-sleep to more than 200 ms. Your problem was that you did the work in the UI thread and this way it never gets updated. For better visibility, just change the font color: private void Form1_Load(object sender, EventArgs e) { Task t = new Task(() => StartUpdate()); … Read more
[ad_1] If you call your executable, for instance, with one of these $ ./executable one foobar > program.exe one foobar You get argc == 3 argv[0] ==> “./executable” or “program.exe” argv[1] ==> “one” argv[2] ==> “foobar” argv[3] == NULL argv[2][0] == ‘f’ argv[2][1] == ‘o’ argv[2][2] == ‘o’ argv[2][3] == ‘b’ argv[2][4] == ‘a’ argv[2][5] … Read more
