[ad_1] What is the use case of the declaration of array like below in C-Language (It is valid one dont say it is error) [duplicate] [ad_2] solved What is the use case of the declaration of array like below in C-Language (It is valid one dont say it is error) [duplicate]
[ad_1] Snippet 1 char a[200],*p; Defined a block of 200 characters ,a, and a pointer, p, to a block of one or more characters. gets(a); // cin.get(a,200); Read some user input into memory block a p=a; Points p at block a. p can now be used as a reference to the same thing as a … Read more
[ad_1] Case B is not async-await. If you have a thread, and this thread has to start a fairly lengthy process in which it has nothing to do but wait, usually because someone / something else performs the operation, then your thread could decide to do something else instead of waiting for the operation to … Read more
[ad_1] It is just logic: whole expression combined by and is true only when both parts are true. So when your loop met first : character, expression is false and loop has been stopped. Based on your description, your code should look like while (!(json[z-2] == ‘s’ && json[z] == ‘:’)) { z++; } or … Read more
[ad_1] This produces a stack-overflow, because there is a recursive call on the hour, when you try to get it. Here t.hour, you try to get the value of hour. This we call the getter, which returns hour / 3600. This will call again the hour and so on and so forth, until the stack … Read more
[ad_1] Use Integer.TryParse to handle the strings potentially not being numbers. Then prompt the user if the input is not parsable to enter valid input. Convert and Parse both will throw exceptions if the string is not an exact number. https://msdn.microsoft.com/en-us/library/f02979c7%28v=vs.110%29.aspx int n = 0; int sum = 0; int i = 0,val = 0; … Read more
[ad_1] Let us say that we have taken an integer, 1234, and split into two parts: 12 and 34: int part_1 = 12; int part_2 = 34; To sum or add, we can use the addition operator: int sum = part_1 + part_2; cout << “Sum is: ” << sum << endl; Edit 1: Playing … Read more
[ad_1] Let’s step through your code static void Main(string[] args) { int input = 7; int zeroes = 0; List<int> myList = ATM(input); mylist => [3,2,1] foreach(var number in myList.ToArray()) { if (number != 0) { myList.AddRange(ATM(number)); } else { continue; } after 3 mylist => [3,2,1,1,1,0] after 2 mylist => [3,2,1,1,1,0,1,0,0] after 1 mylist … Read more
[ad_1] As already noted in the comments, char *str[10]; depicts an array of char pointers. This would be useful, for example, if the length of strings this object will contain is not known until run-time. Once at run-time, it is determined that the length of string for each char * needs to be 25 (for … Read more
[ad_1] Your code is unnecessarily complex. use default .Net implementations to make your code readable and understandable. string skaiciai = “skaiciai.txt”; string[] lines = File.ReadAllLines(skaiciai); // use this to read all text line by line into array of string List<int> numberList = new List<int>(); // use list instead of array when length is unknown for … Read more
[ad_1] It depends on the variable. If the variable is a string it’s no problem and you can do it like this: Label1.Text = yourString; However when the variable is of another type like int it’s a abit harder to do. Luckily you are working with a label that accepts string and most types are … Read more
[ad_1] To acomplish your goal you need to do two steps: Read the entire file. Transform to appropiate structure. Thanks to LINQ you can accomplish quickly: var cells = (from l in System.IO.File.ReadAllLines(“myfile.txt”) select l.Split(” “.ToArray(), StringSplitOptions.RemoveEmptyEntries)).ToArray(); Now you can access the cells like this: var value = cells[1][2]; 3 [ad_2] solved C# Readint a … Read more
[ad_1] I’m not sure if the small scope you share with us is enough to give a meaningful answer; but neither I’m sure sharing with us a bigger part of the code would be really helpful. Anyway, with the small information you gave us, I can think of a couple suggestions: 1. Create a custom … Read more
[ad_1] I feel bad writing this answer, but hopefully this will prevent all other answers and close the ticket. private static int ToPercentage(double d) { return (int)(d*100); } EDIT: Thanks Devid for the suggestion 🙂 TIL how to make an answer a community wiki post! 2 [ad_2] solved Converting decimal percentage to int
[ad_1] Every widget constructor should never block the main message loop! The main message loop looks usually like this: int main(int argc, char *argv[]) { QApplication a(argc, argv); MainWindow w(nullptr); w.show(); int r = a.exec(); return r } In your case your MainWindow ctor never returns, so w.show() is never called and a.exec() (main messgae … Read more
