[Solved] Why compilers put zeros into arrays while they do not have to?

by

[ad_1] A structValue{}; is aggregate initialization, so 0 are guaranteed. As A has no user provided constructor because explicitly defaulted constructors do not count as such, the same applies for value initialization as in A* psstructValue = new A();. For the default initialization cases: Reading uninitialized variables is UB, and Undefined behavior is undefined. The … Read more

[Solved] Question: Is There A Way To Format White-space Like This In C#?

by

[ad_1] I personally love using Linq, also this works with any number of columns and will calculate the distance needed for each column. void Main() { string[][] StringArray = new string[][] { new [] {“Name:”, “John”, “Jones.”}, new [] {“Date of birth:”, “Monday,”, “07/11/1989.”}, new [] {“Age:”, “29”, “Years old.”}}; var lines = FormatWhiteSpace(StringArray, Padding: … Read more

[Solved] C++ char getting errors? [closed]

by

[ad_1] These both statements are wrong char[] name = { “Nitish prajapati” }; char* namePointer = &name ; In C++ valid declaration of an array looks like char name[] = { “Nitish prajapati” }; As for the second statement then there is no implicit conversion from type char ( * )[17] to char *. The … Read more

[Solved] Size of char pointer

by

[ad_1] names is array of character pointers. So names[0] is char * pointing to “Miri”. And similarly for other subsequent items. 3 [ad_2] solved Size of char pointer

[Solved] Running a hello world HElib program

by

[ad_1] Ah, so this is a misunderstanding of the operations being performed. Notice the constant p=2. I have the text All computations are modulo 2.. Perhaps also stating All inputs are modulo 2 would help hammer the point home. Lets look at some of our computations: 0 + 0 mod 2 = 0 2 + … Read more

[Solved] How to compute the average for every n number in a list [closed]

by

[ad_1] public List<double> Average(List<double> number, int nElement) { var currentElement = 0; var currentSum = 0.0; var newList = new List<double>(); foreach (var item in number) { currentSum += item; currentElement++; if(currentElement == nElement) { newList.Add(currentSum / nElement); currentElement = 0; currentSum = 0.0; } } // Maybe the array element count is not the … Read more

[Solved] Lambda convert to LINQ

by

[ad_1] Lambda LINQ is still a link expression. However, the statement should look something like this: var train2 = (from c in db.sample1 join t in db.sample2 on c.CertificateId equals t.CertificateId where c.Year.Value.Year == year && c.TrainingTypeId.Value == trainingTypeId && c.IsApproved.Value && t.EndDate >= DateTime.Now select c).Distinct(); 8 [ad_2] solved Lambda convert to LINQ

[Solved] Parse string with arithmetic operation [duplicate]

by

[ad_1] Maybe using regular expressions you can do something like… String sExpression = “23 + 323 =”; int nResult = 0; Match oMatch = Regex.Match(@”(\d+)\s*([+-*/])\s*(\d+)(\s*=)?”) if(oMatch.Success) { int a = Convert.ToInt32(oMatch.Groups[1].Value); int b = Convert.ToInt32(oMatch.Groups[3].Value); switch(oMatch.Groups[2].Value) { case ‘+’; nResult = a + b; break; case ‘-‘; nResult = a – b; break; case ‘*’; … Read more

[Solved] Console Application to count all ‘#’ characters in a text file

by

[ad_1] The problem is that ‘#’ (symbol your looking for) is a special symbol in regular expressions and so, should be escaped: static void Main(string[] args) { //String fileName = @”C:\Documents and Settings\9chat73\Desktop\count.txt”; // To search dinamically, just ask for a file: Console.WriteLine(“Enter a file to search”); String fileName = Console.ReadLine().Trim(); if (File.Exists(fileName)) { Console.WriteLine(“Enter … Read more

[Solved] Same average function c++ [closed]

by

[ad_1] Array[i].getAverageGrade is a function. You can compare that function to another function (like Array[j].getAverageGrade) but what you really want is to call that function compare the result to the result of calling the other function: Array[i].getAverageGrade() == Array[j].getAverageGrade() BTW: Please keep in mind what others have told you about comparing double values. 1 [ad_2] … Read more

[Solved] C++ program functions arrays [closed]

[ad_1] I would declare the functions the following way const size_t SCORE_NUM = 5; const size_t STUDENT_NUM = 100; // at least not less than the number of records in the file size_t inputScores( std::ifstream &, std::string[], double[][SCORE_NUM], size_t ); double computeAverage( const double[], size_t ); char computeLetterGrade( double ); void printGrades( const std::string[], const … Read more
