[ad_1] Your definition for the array is incorrect, it should be: int t[n]; Note that you do not need to declare a local array for your purpose, but you should check for proper conversion by scanf. Note also that insert_end probably does not take a list *** argument. Here is an improved version: void tab2list(int … Read more
[ad_1] As per your requirement, round decimal up to 2 place using following way : 1) Use Math.Round(). var vatprice= Convert.ToDecimal(Math.Round(dt.Rows[0][5], 2)); 2) second way is var vatprice=Convert.ToDecimal(dt.Rows[0][5].ToString (“#.##”)); [ad_2] solved how to convert decimal value into int in c# [closed]
[ad_1] A binary operator member should only take one parameter, the right-hand argument – the left-hand argument is *this. template<int NMAX> typename FastOut<NMAX>::Flags FastOut<NMAX>::operator&(Flags rhs) const { // Return *this & rhs } [ad_2] solved I can’t get enum class operators to work
[ad_1] No, there is not much use. Probably checking the variable being null or not is just as expensive as setting it to null one time too many. If it was a property, with additional logic behind it, it could make sense to test it before, but that should actually be the responsibility of the … Read more
[ad_1] Loading report is a single operation (two at most: query and displaying the viewer), so that you can’t split it do display progress accurately. You could display progressless bar or use animated image like this one: That operation has to run in parallel to UI thread (use Thread, Task or BackgroundWorker), otherwise your progress … Read more
[ad_1] It doesn’t make any sense to mark local method variables as private. That is what is causing your errors. Why the compiler is giving you an } expected error, I’m not sure. I’m guessing that the compiler is assuming that private int howmanybars is being interpreted as a private instance field definition, which cannot … Read more
[ad_1] The problem is that you’re storing pointers into cstr in argv, but then you’re deleting cstr at the end of the parse() function. Get rid of: delete[] cstr; Also, you should pass argc by reference. Otherwise, when you update it in the parse() function it won’t update the caller’s variable. So it should be: … Read more
[ad_1] An operator is a function which can be represented with a special syntax. So the following, if defined on a class MyClass: T MyClass::operator% (int k); can be called as follows: MyClass a; int k = 1; T answer = a % k; The other operator: T MyClass::operator[] (int k); Can be called by: … Read more
[ad_1] Neater, more linq: var data = GetData(); foreach (var v0 in data) { if (v0.Key.Item3 != string.Empty) continue; //Get all related data var tr_line = data[v0.Key]; sb.AppendLine(tr_line.First()); var hhLines = from v1 in data where v1.Key.Item2 == string.Empty && v1.Key.Item1 == v0.Key.Item1 select data[v1.Key]; foreach (var hh_line in hhLines) { sb.AppendLine(hh_line.First()); var grouping = … Read more
[ad_1] You will have to draw every line and circle through your code,there won’t be a shortcut for that. Though, I would suggest using other graphics libraries like OpenGL. In other languages certain IDEs have features wherein you don’t have to write a code but you can manually design your graphics on a editor window … Read more
[ad_1] The only thing missing is initialization of the property – it is null otherwise (meaning that calling Add on it will throw a NullReferenceException). DatabaseLogger.ILogger logger = new DatabaseLogger.Logger(); logger.customProperties = new Dictionary<string, string>(); logger.customProperties.Add(“companyName”, “Company”); logger.customProperties.Add(“application”, “application”); Though this might be better done in the Logger constructor: public Logger() { customProperties = new … Read more
[ad_1] I think this is what you want, List<string> keys = new List<string>() { “name”, “age”, “param3” }; string url = “http://www.test.com/test.aspx?testinfo=&|&;”; Regex reg = new Regex(“&”); int count = url.Count(p => p == ‘&’); for (int i = 0; i < count; i++) { if (i >= keys.Count) break; url = reg.Replace(url, keys[i], 1); … Read more
[ad_1] Try something like this: #include <iostream> #include <string.h> #include <vector> #include <fstream> #include <cstdlib> #include <stdio.h> #include “tm.h” using namespace std; tm::tm(char *fn) { current = “”; readFile(fn); } void tm::readFile(char *fn) { char temp; string word = “”; ifstream indata; bool blank = false; indata.open(fn); //opens the file if(!indata) //error message if the … Read more
[ad_1] You need to toupper every single character, e.g. while( (leido = read(0,&buffer,sizeof buffer)) > 0){ for (int i=0; i<leido; i++) { buffer[i] = toupper((unsigned char)buffer[i]); } retorno = write(1,&buffer,leido); } 2 [ad_2] solved How can I use the function toupper() in this code? [closed]
[ad_1] Using the algorithm you propose in your question (i.e. to first find all unique values and then find the lowest one), a possible implementation looks like this: #include <stdio.h> #include <stdlib.h> // NOTE: The second parameter array_size specifies the number of // int elements in the array, NOT the size of the array in … Read more
