#include <api.h> is the way you include a system header. (That is, the header for a library installed on your system.) It does not search in the directory of the source file or in directories specified in -I command line arguments. #include “api.h” is the way you include your own headers. (But it will also … Read more
TL;DR #include <vector> std::vector <unsigned long long int> triangleNumbers(0); int main() { triangleNumbers[0]=10000000000; } You have an empty vector, and the very first line in main leads to undefined behavior since you’re trying to access item 0 (there is no such item). Live Example using operator [ ] Live Example showing what vector::at() does Note … Read more
It’s quite common, actually almost all templates have certain requirements towards their arguments. Those are usually implicitly clear from how the template parameter is used, but you can improve the error messages by using type traits. In C++11, they are available from the standard library via #include <type_traits>, otherwise look into Boost.TypeTraits. With C++11, the … Read more
Introduction A 2D array pointer is a pointer that points to an array of elements, each of which is an array of elements. It is a powerful tool for manipulating data in a two-dimensional array. However, it is important to note that a 2D array pointer does not apply to both dimensions of the array. … Read more
Introduction Char () and int () are two functions in C++ that are used to convert data types. Char () is used to convert an integer value to its corresponding character value, while int () is used to convert a character value to its corresponding integer value. These functions are useful when dealing with data … Read more
Introduction Unity3D is a powerful game engine that allows developers to create complex and interactive 3D games. One of the most important aspects of game development is the use of variables. Variables are used to store data and can be used to control the behavior of objects in the game. In this tutorial, we will … Read more
Introduction If you are looking for a way to remotely host a C# Web Service with a custom URL, then you have come to the right place. In this article, we will discuss the steps you need to take in order to successfully host a C# Web Service with a custom URL. We will cover … Read more
Is MonoBehaviour.Destroy(gameObject) what you’re after? I’m not really sure what part of the process you are struggling with? Edit: With the clarification, below is the revised answer: Track the position of the players co-ordinates, and when an object finds that its own co-ordinates are less that players co-ordinate minus the offset of where the player … Read more
In theory you can, by simulating individual data structures or even the entire memory (static data, heap and stack) with arrays. But the question is whether this is very practical; it may involve having to rewrite every pointer-based standard library function you need. Anyway, there’s a nice explanation on Wikipedia: It is possible to simulate … Read more
one of the problems in your code is, that you never check the results of your operations, there should be: M[i] = imread(“Klasa_pierwsza\\” + lista[i]); if ( M[i].empty() ) { cerr << “Klasa_pierwsza\\” + lista[i] << ” could not be loaded !” << endl; continue; } // … std::vector<cv::Vec4i> lines; cv::HoughLinesP(bw, lines, 1, CV_PI / … Read more
Here is a demonstrative program written in C++ that you can use as an algorithm and rewrite it in C #include <iostream> #include <iomanip> #include <stack> #include <cstring> bool balance( const char *s, std::stack<char> &st ) { const char *open = “({[<“; const char *close = “)}]>”; if ( *s == ‘\0’ ) { return … Read more
In expressions an array designator is implicitly converted to the pointer to its first element. Adding an integer to a pointer you will get again a pointer. It is so called the pointer arithmetic. Thus for example if you have an array int a[] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, … Read more
You must protect against dividing by zero. Specifically, any time the value of q may be zero. At a minimum you need to test q each time you enter your function. With the additional code you posted, if you insure q isn’t 0 before calling geoprogress, that is sufficient as well. Regardless, a test in … Read more
You need CookieCollection to get cookies and set UseCookie to true in HtmlWeb. CookieCollection cookieCollection = null; var web = new HtmlWeb { //AutoDetectEncoding = true, UseCookies = true, CacheOnly = false, PreRequest = request => { if (cookieCollection != null && cookieCollection.Count > 0) request.CookieContainer.Add(cookieCollection); return true; }, PostResponse = (request, response) => { … Read more
I’m not going to answer with a complete solution (and you are free to improve your question so you get better answers later), but regarding the question title, here are some hints. Your declaration char displaymenu(int num1, int num2); and your definition char displaymenu(int &num1 = num1, int &num2 = num2) should have the same … Read more
