[ad_1] float is an alias for single. float C# – MSDN (Remember that float is an alias for the System.Single type.) [ad_2] solved what the need of using single and float keywords separately . when we have to use single in the real time scenario?
[ad_1] There are several issues: Instead of calling initialisation(&LBO); which is not really wrong, just write: LBO = NULL; Then don’t hide pointers with typedefs, it only adds confusion. Instead of: typedef struct noeud { int adresse, taille, temp; struct noeud* suivant; } *liste; Write: struct noeud { int adresse, taille, temp; struct noeud* suivant; … Read more
[ad_1] \+\d{1,4}-(?!0)\d{1,10}\b Breakdown: \+ Match a literal + \d{1,4} Match between 1 and 4 digits inclusive – Match a literal – (?! Negative lookahead, fail if 0 this token (literal 0) is found ) \d{1,10} Match between 1 and 10 digits inclusive \b Match a word boundary Demo (with your examples) var phoneRegexp = /\+\d{1,4}-(?!0)\d{1,10}\b/g, … Read more
[ad_1] Q: How do I fix problem 1 … ? 10 ^ i is 10 exclusive-or’ed with i. It is not 10i. To find the integer portion of log10(num) int i_portion = 0; if (num <= 0) Handle_elsewhere(); else { int i_portion = 0; int n = num; while (n >= 10) { n /= … Read more
[ad_1] It is not possible to put generic constraint about specific constructor availabilty, so you cannot guarantee inside the method that TDal _dal = new TDal(_connectionString); is possible. I would refactor it then to provide dal externally: public List<TRule> getData<TRule>(TRule perRA, IDal<TRule> dalRA, int acao) { List<TRule> list = new List<TRule>(); try { list = … Read more
[ad_1] Here’s an example: public class Example { public int Result {get; private set;} private Example(int x, int y){ Result = x + y; } public static Example Create(int x, int y){ return new Example(x,y); } } [ad_2] solved Is there a way to add two numbers using a private constructor in C#
[ad_1] Answering the question in the title line: If you use java.util.Vector<E>, then it is addElement. Those would be the closest-match class and method in Java to the C++ template classes that you mentioned in your question. Docs are here: https://docs.oracle.com/javase/8/docs/api/java/util/Vector.html#addElement-E- 2 [ad_2] solved what is the method equivalent to push_back (C++) in java?
[ad_1] For starters there is no elseif statement in C++.There are if and if-else statements in C++. Also you have to remove mistaken semicolons at the end of if or else with if statements. And the conditions are also written incorrectly. A valid else statement can look for example like else if ( dateOfBirth == … Read more
[ad_1] The else branch of the if(fsize==0) conditional in csvwrite() does not fclose(fe). There is a limit on the number of files that can be opened by any one process at once; if you call this enough times, you’ll hit the limit, and the next fopen() will return NULL (and errno will be set to … Read more
[ad_1] You are trying to compile C++ code as C. C and C++ are different languages, and your C compiler is complaining about C++-specific syntax. Try compiling the code as C++. For most compilers it should be sufficient to rename your file main.cpp. 1 [ad_2] solved error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before … Read more
[ad_1] The C Programming Language (second edition): Exercise 1-15 (Celsius to Fahrenheit conversion) – What is wrong with my solution? [duplicate] [ad_2] solved The C Programming Language (second edition): Exercise 1-15 (Celsius to Fahrenheit conversion) – What is wrong with my solution? [duplicate]
[ad_1] Your comparison code is fine. The problem is that you’re not calling the function correctly. You need to call the member function through an object. Otherwise, how will it know that it should be comparing with pepper? if (pepper.sameAge(salty)) { // do something } This is basic to all object-oriented programming — methods are … Read more
[ad_1] My solution to this is a new class: class ShapedPictureBox : PictureBox { public ShapedPictureBox() { } public Color transparentColor = Color.White; public void updateShape() { if(this.Image = null) return; Bitmap bitmap = new Bitmap(this.Image); System.Drawing.Drawing2D.GraphicsPath graphicsPath = new System.Drawing.Drawing2D.GraphicsPath(); for(int x = 0; x < this.Image.Width; x++) for(int y = 0; y < … Read more
[ad_1] Assuming your array is an array of Int32… using (var stream = File.Create(“file.xml”)) { var serializer = new XmlSerializer(typeof(Int32[])); serializer.Serialize(stream, someArrayOfInt32); } Will create a simple XML file that is very easy to understand/modify. To deserialize it, use the Deserialize method. In JSON format : using System; using System.Collections.Generic; using System.Linq; using System.Web; using … Read more
[ad_1] “what should i do?” You simply do this (using the std::system() function): #include <cstdlib> // … if(i == 1) { std::system(“ROBOCOPY D:/folder1 D:/folder2 /S /E”); } else if(i == 2) { std::system(“ROBOCOPY D:/folder3 D:/folder4 /S /E”); } Note that for string literals like “D:\folder3”, you’ll need to escape ‘\’ characters, with another ‘\’: “D:\\folder3”. … Read more
