Introduction [ad_1] If you are looking for a way to run multiple tasks and get the results after all of them have ended, then you have come to the right place. In this article, we will discuss how to run many tasks and get their result after all of them have ended. We will discuss … Read more
[ad_1] strlen(myarray) returns the index of the first 00 in myarray. 0 [ad_2] solved strlen() gives wrong size cause of null bytes in array
[ad_1] I’m guessing here based on the many questions leading up to this. It is pretty obvious that you do not want sample type to be a scalar, but a 2-dimensional array. I will sketch a generic short-cut that would allow you to write mean_square_displacement::operator() to accept those, potentially even without knowing the concrete type(s) … Read more
[ad_1] Move you initialization of count to above the first for loop. Move the if statement after the end of the first for loop. void board::winner(int x, int y) { int count = 0; for (int i = 0; i < col; i++) { for (int j = 0; j < row; xaxis++) { if … Read more
[ad_1] As long as you’re bothered with the for loop syntax, for ( ; lastheight < height ; lastheight++) is perfectly valid, as long as lastheight is defined and initialized previously. Quoting C11, chapter §6.8.5.3 for ( clause-1 ; expression-2 ; expression-3 ) statement […] Both clause-1 and expression-3 can be omitted. An omitted expression-2 … Read more
Introduction [ad_1] The question of who is the winner is a common one, and it can be difficult to answer. It depends on the context of the situation and the rules that have been set. In this article, we will discuss the various ways to determine who is the winner in a given situation and … Read more
Introduction [ad_1] This tutorial will provide a step-by-step guide on how to combine two single dimensional arrays into a two-dimensional array in C#. We will discuss the different methods of combining the two arrays, as well as the advantages and disadvantages of each approach. We will also provide code examples to illustrate the different approaches. … Read more
[ad_1] Firstly, you’re going to have to either define currentYear within the try/catch (both try and catch due to way the compiler interprets code paths) or upon declaration. Otherwise, you’ll get CS0165: Use of unassigned local variable ‘currentYear’ at the line with age = findAge(currentYear, birthYear) The following code works: static void CollectUserInfo() { // … Read more
[ad_1] I didn’t check your code but… No, you can’t use fixed weight like that. Each node in your hidden layer will get larger and larger values as you increase the amount of inputs. Sigmoid will scale the large values to 1. Think about it: Let’s say that you have 100 inputs each having “random” … Read more
Introduction [ad_1] Quadratic equations are a type of mathematical equation that involve a variable raised to the second power. Solving a quadratic equation can be a difficult task, but with the right knowledge and tools, it can be done quickly and easily. In this article, we will discuss how to solve a quadratic equation using … Read more
[ad_1] You can pass objects to functions as arguments. Here, fnMainMenu takes a reference to a constant std::string object as parameter and prints it out to stdout: void fnMainMenu(const std::string& msg) { std::cout << msg << “\n”; } Then fnLogin() can call the function and pass it any string it likes: void fnLogin() { std::string … Read more
Introduction [ad_1] Solution The error you are getting is likely due to the fact that you are trying to assign a value to a variable that is not of an integral or unscoped enum type. To fix this, you will need to make sure that the type of the variable you are assigning a value … Read more
[ad_1] using System.Drawing; using System.Drawing.Imaging; void Main() { double hue = 3.3; double sat = 0.4; double val = 0.9; var wheel = new ColorPicker(400); var img = wheel.DrawImage(hue, sat, val); using (var g = Graphics.FromImage(img)) { var pen = val < 0.5 ? Pens.White : Pens.Black; var wheelPosition = wheel.GetWheelPosition(hue); g.DrawEllipse(pen, (float)wheelPosition.X – 5, … Read more
[ad_1] mlorbetske’s regex can be rewritten a bit to remove the use of conditional regex. I also remove the redundant 0-9 from the regex, since it has been covered by \d. ^[a-zA-Z\d](?:[a-zA-Z\d]|(?<![._/\\\-])[._/\\\-]){0,49}$ The portion (?:[a-zA-Z\d]|(?<![._/\\\-])[._/\\\-]) matches alphanumeric character, OR special character ., _, /, \, – if the character preceding it is not a special … Read more
Introduction [ad_1] Garbage characters are a common issue in C programming. They are characters that appear in a program’s output that are not intended to be there. These characters can cause a variety of problems, from incorrect output to program crashes. Fortunately, there are a few simple steps that can be taken to solve this … Read more
