The identifier private restricts access to class methods and class friends. The static identifier indicates there is only 1 instance of the variable to be shared among all children. So, private static means a data member that has only one instance, regardless of the number of instances, and only class methods and class friends can … Read more
I would use a list of tuples like this: double TotalDebts = 30000; list<Tuple<int, double>> AllDebits = new list<Tuple<int, double>>(); for (int i = 0; i < 250; i++) { if (TotalDebts > 0) { double DebtsLessIncome = Convert.ToDouble(TotalDebts – 1000); double InterestCharged = Convert.ToDouble((DebtsLessIncome * 5) / 100); double InterestDebt = Convert.ToDouble(DebtsLessIncome + InterestCharged); … Read more
First of all, you aren’t guarenteed to get a segmentation fault, or any defined behavior, for triggering undefined behavior, such as modifying a string literal. Though on Linux, string literals are put into read-only memory, so modifying them on Linux will usually result in a segmentation fault. So why doesn’t this code trigger a segfault? … Read more
It is only a logical error if you consider it to be one. If however the change of the value of the static variable with each constructor is exactly what you WANT it to do, then it is not a logical error. As in the comments already mentioned, one example is to count all constructors. … Read more
Thanks everyone for the help. I have stumbled upon a link that clearly highights the difference between the two versions and is proving to be very informative to me. I am posting it here so that if anyone has the same question as mine, they can refer here. http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p1319r0.html solved DIfference in function signatures between … Read more
So, where you call GetSingleLocationInfo, you are calling an async method. GetSingleLocationInfo calwill therefore run as far as the await statement then return stright to the caller, before the it httpClient.GetStringAsync(hereNetUrl); has returned. To fix this, you need to await on your call GetSingleLocationInfo before trying to access the variable. 1 solved why instance variable … Read more
I think you have non printable characters before each ‘$’ in a.txt even there are not indicated through notepad, as you can see the count written reach 7 then 5 etc, this is not possible if the text is the one we see a.txt contains only ascii characters or is UTF8 or something like that … Read more
So the thing is, Python does not have the same ternary operator. condition?true:false => true if condition else false To implement the line: return(isalpha(ch) ? accvs[ch & 30] : 20) in python, you have to do the following: return (accvs[ord(ch) & 30] if ch.isalpha() else ’20’) solved Trying to change or interpret the C code … Read more
If you want to use Regex, you can use the following. “( |:).*” Example, var list= @”Summoner1 joined the lobby. Summoner2 jonied the lobby. Summoner3: Top Summoner4: ADC”; var result = list.Split(new []{Environment.NewLine},StringSplitOptions.RemoveEmptyEntries).Select(x=> Regex.Replace(x,”( |:).*”,string.Empty)); Update: Based on Comment var result = string.Join(“|”,list.Split(new []{Environment.NewLine},StringSplitOptions.RemoveEmptyEntries).Select(x=> Regex.Replace(x,”( |:).*”,string.Empty))); Output Summoner1|Summoner2|Summoner3|Summoner4 7 solved How to crop strings using … Read more
Looking at what you are asked to do I think you just have to determine the highest and lowest int in the array and point to. You sort the array thats slower. I think it should look like that: #include<iostream> using namespace std; int main() { int kre_arr[10]; int *low; int *high; cout<<“Enter 10 Integers: … Read more
In the first case, Derived is a class which can be used to declare a variable. In the second Derived is a variable name of type std::vector<Base>. In the case of the class it is possible to produce undefined behaviour with the following code: void deleter(std::vector<Base>* ptr) { delete ptr; } void buggy() { auto … Read more
I see your code, it have 2 problems: You get data but don’t return data for View. When return PartialView, We are can’t “public ActionResult SearchResutl()”, It can remove. Code fix same that: public ActionResult MemberSearch() { return View(); } [HttpPost] public ActionResult MemberSearch(ViewModesTest m) { var d = db.Members.Where(s => s.Name == m.Name && … Read more
You can split the string on / and then use int.TryParse on the first element of array to see if it is an integer like: string str = “1234/xxxxx”; string[] array = str.Split(new []{“https://stackoverflow.com/”}, StringSplitOptions.RemoveEmptyEntries); int number = 0; if (str.Length == 2 && int.TryParse(array[0], out number)) { //parsing successful. } else { //invalid number … Read more
A simple way using std::setw and std::setfill is this: int hour = 0; int minute = 0; int second = 59; std::cout << std::setw(2) << std::setfill(‘0’) << hour << “:”; std::cout << std::setw(2) << std::setfill(‘0’) << minute << “:”; std::cout << std::setw(2) << std::setfill(‘0’) << second << endl; It will print: 00:00:59 0 solved How … Read more
Let’s look at the first two lines of your code: str = (char *) malloc(15); strcpy(str, “63tczfqV4nqB2YnH9iFJbGvGyyDkvK341rrj0G0mo1PEYniOVHejVIFIQnJzHSSMRbuyGMCZ4M5HFMV4y1q4QgYqyxp2XkTjxaolKTkaw1r25S2Emz061tw1”); At this point, you have broken the rules of the C language. strcpy will write past the end of str which causes undefined behavior. Everything that happens after this point is kinda up in the air. 5 solved … Read more
