[ad_1] Yes you can’t! The IEnumerable generates new Lists every time it is evaluated; it says so right there in your code: .Select(x => new List<int>{x}); When you call Dump(), it is evaluated. When you call First(), it’s evaluated again. Then Dump again. All new Lists! If you evaluate the IEnumerable before putting it in … Read more
[ad_1] When two “>” characters are near each other, they need a space in between so that it is not interpreted as the “>>” operator. After doing that change, the prototype compiles. #include <iostream> #include <vector> #include <iostream> template <typename T, typename Q> std::vector<std::pair<T, Q> > sortPairIntoVector( std::pair<T,Q>, std::vector<std::pair<T, Q> >); template <typename T, typename … Read more
[ad_1] A better way to achieve what you’re trying to do overall would be to use an exception. Consider if we wrote AddNumbers as such: public static int AddNumbers(int number1, int number2) { int result = number1 + number2; if(result <= 10) { throw new Exception(“Should be more than 10”); } return result; } and … Read more
[ad_1] Hidden? It’s not hidden. What does that even mean? I do remember that you have to explicitly use it in Java Only in some circumstances. A variable called name could be known inside the class and also be the name of a parameter in a method. Example: class Test { String name; public void … Read more
[ad_1] You can only overload the actual C# operators, it isn’t possible to create your own. The list of overloadable operators is here 1 [ad_2] solved Operator with more than one charecter C#
[ad_1] If its a c# code then you can use contains to check the stageID if(stageID.Contains(1)) { //your code } else if(stageID.Contains(2)) { //your code } else { // your code } if its a SQL code DECLARE stageID number(3) := 100; BEGIN — check the boolean condition using if statement IF( stageID < 20 … Read more
[ad_1] This cannot be done because once the class definition is set, that’s it. The best you can do to retrieve an array of only the Name and Address properties contained in an object is to use LINQ to perform an operation on each element, in which case you can then retrieve an array of … Read more
[ad_1] In your interface you have it defined as Task<IEnumerable<TabMain>> Gettabs(); but you implement it like this public async Task<IEnumerable<TabMain>> GetTabs() C# is a case sensitive language, so you need to either change your implementation method name or your interface method name. I would change the interface method name to GetTabs to go with the … Read more
[ad_1] You could try following code, it uses private field to stroe all permutations generated by methods finding permutations: private static List<string> _permutations = new List<string>(); public static Main(string[] args) { string testString = “abc”; TestMethod(testString); // You need to handle case when you have last permuation in a list string nextPermutation = _permutations[_permutations.IndexOf(testString) + … Read more
[ad_1] public final boolean ParantezKontrol(String input) { return ParantezKontrol(input, 0); } //Java does not support optional parameters. So you can overload this method //ORIGINAL public bool ParantezKontrol(string input, int numOpen = 0) public final boolean ParantezKontrol(String input, int numOpen) { if (numOpen < 0) { return false; } if (isNullOrEmpty(input)) { return numOpen == 0; … Read more
[ad_1] As far as I understand you are comfortable with replacing words in a single paragraph and that you are doubtful regarding text with multiple paragraphs. Please look into a function called “getline()” function. This function reads entire your text until it encounters a “\n” element (Next line) So you can use this getline function … Read more
[ad_1] There is a quite simple answer to how to encrypt files. This script uses the XOR encryption to encrypt files. Encrypt the file a second time to decrypt it. #include <iostream> #include <fstream> #include <string> using namespace std; void encrypt (string &key,string &data){ float percent; for (int i = 0;i < data.size();i++){ percent = … Read more
[ad_1] Try using regular expressions: String source = “Invoice No:< 12345sd ) <1234567890>”; // {10} 10 characters exactly // {10,} 10 characters or more // {,10} 10 characters or few // {5,10} from 5 up to 10 characters var matches = Regex .Matches(source, @”<([^<]{10})>”) .OfType<Match>() .Select(match => match.Groups[1].Value) .ToArray(); // Or FirstOrDefault(); if you want … Read more
[ad_1] #include <cstdlib> … if(rand()%2)a++; else a–; That’s not very hard to do. Its simple trick. 0 [ad_2] solved Radomly add or subract 1; [closed]
[ad_1] I think what you are asking is not possible. But you can use constants. const string s = “I’m a constant and I’ll not change”; But the word variable itself speaks itself. It varies But for your sake how about this: struct Uoolean { } A empty struct? No matter what object you create … Read more
