[ad_1] The simple answer that won’t help you much is that this is done for backwards compatibility with C, that has exactly the same syntax to define variables. The rationale for that design would have to come from the creators of C, and I don’t really know it. What I do know is that most … Read more
[ad_1] You have your counter incrementing in the wrong place. int count = 0; foreach (string[] element in logBook) { Console.WriteLine (“#{0}: {1}”, count, element[0]); count++; // Increment after you print } [ad_2] solved C# How to start list count on 0 [closed]
[ad_1] You just need to delete the array referenced by del: delete[] del; You are already deleting the arrays referenced by hello and bye: delete[] * del; delete[] * (del + 1); Though this would be more idiomatic: delete[] del[0]; delete[] del[1]; Or even better, avoid using new and delete altogether, taking advantage of modern … Read more
[ad_1] But it doesn’t works, il only returns 1 and there are at least 2 objects in my map that have same id It’s a std::map. You cannot have two objects with the same key, and I assume you’re trying to use the m_id filed of O as your key. Try using std::multimap instead. And, … Read more
[ad_1] Please ask only one question per question. Is Int32 a = new Int32() equal to int a ? No. It is the equivalent of int a = 0; If not: How its possible to write a.ToString() ? Ints have a method called ToString. You called it. Do we have primitive types in C#? The … Read more
[ad_1] The problem is likely that you’re starting your counter variables at 1, then using that as an index into the array, but array’s are zero-based in c# so you’re essentially skipping the first item at 0 and then trying to access an item that’s out of the bounds of the array. It’s also not … Read more
[ad_1] Suppose that v is a vector, only elements v[0] to v[v.size() – 1] are available and v[v.size()] is out-of-range. Therefore, for(int i=0;i<=weights.size();i++) and for(int it =0;it<=values.size();it++) should be for(int i=0;i<weights.size();i++) and for(int it =0;it<values.size();it++) (use < instead of <=) 4 [ad_2] solved libc++abi.dylib: terminating with uncaught exception of type std::out_of_range: vector Abort trap: 6. … Read more
[ad_1] What you appear to be looking for is the furthest neighbour between points. Writing a brute force solution is trivial, just compare distances between every possible pair of points. As per the link, far better solutions exist. Edit: Distance between two points is double distance(double x1,double y1,double x2, double y2) { return sqrt((x2-x1)*(x2-x1) + … Read more
[ad_1] Can you do in C++ something like this: Yes. struct Lecture { }; struct Carriage { Carriage(const Lecture&) { } void runIt() { } }; int main() { Lecture le; Carriage ca = le; ca.runIt(); } The problem is, when I am trying to invoke a method which belongs to Lecture class the methods … Read more
[ad_1] Well I solved the problem i was installing wrong SDL2 libraries: used these: sudo apt-get install libsdl2-dev sudo apt-get install libsdl2-image-dev sudo apt-get install libsdl2-ttf-dev 1 [ad_2] solved SDL2 Exporting to linux
[ad_1] What is the current code you have? A C# example would look something like this: // Assuming ‘items’ is an Enumerable type containing the list of items in the order var totalCost = 0; for (var i in items) { // Accumulates the cost of each item at a 25% discount totalCost += 0.75 … Read more
[ad_1] As you use username and password of type char, you can’t read them by %s (for strings) in the scanf function, use %c (for chars) instead. If your username and password contain more than 1 char, use a char array. For example char username [20]. Now you can fill them in the scanf function … Read more
[ad_1] You are writing to memory which you do now own i.e. was not handed back by malloc , calloc or realloc. This results in undefined behaviour. Your program can do anything at all, including not producing any error message or core dump. 7 [ad_2] solved Not generation of core [duplicate]
[ad_1] yes that is correct. If they would just write w = 1.0 / w; division by zero might occur. So adding the ternary operator here is an OK way to handle this. A more intuitive alternative would be: if (w != 0.0f){ w = 1.0f / w; } 2 [ad_2] solved What does this … Read more
[ad_1] You either meant FindObjectsOfType <- mind the ‘s‘ or following your variable names it should be simply only one instead of an array: public ResetOnRespawn ObjectToReset; [ad_2] solved error CS0029: Cannot implicitly convert type `ResetOnRespawn’ to `ResetOnRespawn[]’ c# unity [closed]
