[ad_1] We don’t have the full details on your string class, so this is hard to reproduce. However, when you call sensors[0] = sensor1; you are copying your Sensor, but haven’t defined an assignment operator (or copy constructor for that matter). You also do this in the Car constructor with (*(m_sensors + i)) = Sensor(*(sensors … Read more
[ad_1] In GeeksForGeeks, overloading is defined to be “a feature in C++ where two or more functions can have the same name but different parameters.” Constructor can be overloaded by allowing for same names and different parameters. For example, you can refer to this. Nesting functions is not supported by C++. Please refer to this … Read more
[ad_1] The best you can achieve is to have two separate configuration files, then have the code of one method read the “main” config file (using the ordinary ConfigurationManager.AppSetting[“”] code) and other method read the configuration file of the class library using such code: Configuration config = ConfigurationManager.OpenExeConfiguration(dllFilePath); KeyValueConfigurationElement element = config.AppSettings.Settings[appSettingKey]; string value = … Read more
[ad_1] If you haven’t enabled vsync, frames swap as often as possible (if you haven’t added artificial pause). If you pushed high load on graphics card, it is likely that your program is GPU-limited (CPU have nothing to do and standing idle waiting for GPU to finish drawing). When your program is invisible, drawing costs … Read more
[ad_1] This is actually a rather interesting error; the error message doesn’t do much to tell you what the problem is. My initial speculation was largely incorrect, but I’ve left it in place for now. See below. This code: #ifndef uint32_t #define unsigned int uint32_t; #endif is incorrect. The name of the macro being defined … Read more
[ad_1] As the error says: structure xmlNode has no member “d”. If you want to compare the content of the node, use the member “content”: xmlStrcmp(cur->content, (const xmlChar *)”d”)) 2 [ad_2] solved C++ program error Libxml2 [duplicate]
[ad_1] Sorry that I won’t go through your example and your intermediary function; the issue you’re having occurs due to double being insufficient, not the long long. It is just that the number grows too large, causing it to require more and more precision towards the end, more than double can safely represent. Here, try … Read more
[ad_1] You can do this: var str = “asp,mvc,c#,wpf”; var anotherStr = “<b>asp</b>,<b>wpf</b>”; var myArr = anotherStr.Replace(“<b>”, “”).Replace(“</b>”, “”).Split(‘,’); foreach (string value in myArr) { str = str.Replace(value, “<b>” + value + “</b>”); } Console.WriteLine(str); 2 [ad_2] solved Replace the particular part of string? [closed]
[ad_1] Access the file in read mode so that you will not get this error. Try this solutionHow do I open an already opened file with a .net StreamReader? [ad_2] solved C#: How to read a file that’s in use by another process
[ad_1] You could add std::fixed like so: float f; std::cin >> f; std::cout << std::setw(10) << std::right << std::fixed << std::setprecision(3) << f << “\n”; 1 [ad_2] solved Float formatting C++
[ad_1] You can define variables with the same names in different scopes. The first variable i is defined in the scope of the main function. In the loop there is another implied nested and anonymous scope for the variables you declare for the loop. For the compiler, the code for(int i = 1; i <= … Read more
[ad_1] You could efficiently extract the month with bitwise operations if you represented the date in a binary format, e.g., 5 bits for the day of the month, 4 bits for the month number, and the rest for the year, rather than as decimal digits. For your example, the date would be (2011 << 9) … Read more
[ad_1] Your code is correctly printing the value of c as 9. You need to clarify on the environment you are running this code. 2 [ad_2] solved (CUDA C) Why is it not printing out the value copied from device memory?
[ad_1] The error is telling you that your declaration of MonitorFromWindow conflicts with the prior declaration. The prior declaration in Winuser.h declared the function with extern “C” linkage, is __declspec(dllimport) and has the __stdcall calling convention. You should remove your erroneous declaration and use that from the header file. 15 [ad_2] solved Windows7.1 SDK: C2373: … Read more
[ad_1] If you want to assign something calculated in a method, then that method needs a return type. It should not be void. public string compute1(double n1, double n2, string opr) { var ans = “”; if (opr == “-“) { ans = (n1 – n2).ToString(); } return ans; } private void cmbOperator_SelectedIndexChanged(object sender, EventArgs … Read more
