[ad_1] Let’s use std::vector: #include <iostream> #include <vector> #include <iomanip> typedef std::vector<double> DoubleArray; DoubleArray v_scalar_prod(double a, double *b, int n) { DoubleArray res(n); for (int i = 0; i < n; i++) { res[i] = a*b[i]; std::cout << std::setprecision(10) << “res = ” << res[i] << ‘\n’; } return res; } int main() { double … Read more
[ad_1] You can either pass the name of a function, such as MyFunction, that has no inputs and returns a string string MyFunction() { return “string”; } or use a lambda expression such as () => “string” 2 [ad_2] solved Passing a func as parameter
[ad_1] To do so you need to just include class.hpp to you class.cpp file. It can be done like #include “class.hpp” So you just need to have both in same folder and after that you need to add above line in class.cpp and then just compile and run the executable. [ad_2] solved How to compile … Read more
[ad_1] I think you need just an example to how to create objects from A: int main() { A obj1(10, 20); // Calls A(10, 20) average: 15 A obj2; // Calls A() -> A(0) -> A(0, 0) average: 0 A obj3(100); // Calls A(100) -> A(100, 0) average: 50 } 1 [ad_2] solved Delegating Constructors … Read more
[ad_1] Almost all programming languages have libraries that help you create a GUI (Graphical User Interface). Most programming languages, including C++, C#, and Java are general-purpose programming languages – you can use them to program whatever you want. For Java for example, see this tutorial: Creating a GUI With JFC/Swing. If you want to write … Read more
[ad_1] The reason your code does not compile as expected is that you have declared the enum Direction to be a nested type, nested inside the outer type Form1, while the referring type Palette is not so nested. A nested type is a type defined within a class or struct. When referred to by code … Read more
[ad_1] After the user has entered the region validate that all values are greater than 0. If they are subtract one from them and process the data just like you are now. if(a < 1) a = 1; if(quantity < 1) quantity = 1; // Subtract 1 from the values a–; quantity–; if (quantity > … Read more
[ad_1] You’ve converted the binary content to a string when you copied it from Wireshark. The result is a string that represents the binary data in a hex Format. Instead of revers the convertion you should use an appropriate methop to copy the data. Try Wireshark’s feature “follow XXX stream” and take the “C Arrays” … Read more
[ad_1] Your code should be : #include <stdio.h> int main() { int r,sales; printf(“Enter sales in dollars : “); scanf(” %d”, &sales); r = sales * 9 / 100+200; printf(“Salary is %d”, r); return 0; } You must first get the value of sales before adding it to a formula. 5 [ad_2] solved why is … Read more
[ad_1] One wrong thing in your check function: you only check the names in the current team to skip that, but you should skip any name that was already put in a team. I already gave you an alternative on another question, so the check function isn’t needed (erasing from the list). Also, when iterating … Read more
[ad_1] Presumably rhs is empty, and so rhs[0] does not exist. Hence an index out of bounds exception is thrown. Try if(!String.IsNullOrEmpty(rhs) && rhs[0] == ‘+’) … 3 [ad_2] solved Index out of bounds in an if statement [closed]
[ad_1] “Better” is arguable, but you could use the built-in method UnionWith and some LINQ for a nice one liner to replace your foreach. Think of it as the closest equivalent to an AddRange, except with the restrictions of a set of course. values.Clear(); values.UnionWith(_values.Select(x => x.Trim())); 2 [ad_2] solved Trim HashSet
[ad_1] What does assert(false); does? It opens an assert window. It’s a mechanism to let the programmer know when a control path that wasn’t supposed to be reached, is, or a condition that wasn’t supposed to fail, does. Basically like: int divide10ByX(int x) { if ( x == 0 ) { assert(!”x can’t be 0″); … Read more
[ad_1] I give it a try, though a lot of questions are open (what type of list, what a column, …). In short: you can use String.Insert to insert text at a specified postition. Assuming you have a List<Foo>, the class Foo has a string property Value (your column). If it’s Length exceeds 100 the … Read more
[ad_1] It looks as if you will need to create a UserControl (right-click your project, New… User Control) for each page of the Wizard, and you will need to implement IWizardPage on your UserControl. Than you have your WizardHost which is a single Form. So to answer your question you will have one Form and … Read more
