[ad_1] My favourite way; hopefully self-explanatory if (a > c) std::swap(a, c); if (a > b) std::swap(a, b); if (b > c) std::swap(b, c); Don’t forget to pass the parameters to Crescator by reference if you want to make them sorted in the caller. [ad_2] solved How to order ascending the variables a , b … Read more
[ad_1] There are multiple issues in the code fragment: The ch = scanf(“%c”, &ch); serves no purpose and does not even properly read a byte from the file into ch. Note that scanf does store the byte into ch, but it is immediately overwritten as you store the return value into ch as well. Just … Read more
[ad_1] The problem is that cin >> y; reads one word, whereas there are two words in “Im qwerty”. In other words, this program always outputs “Your account has been deactivated.” because one word never matches two words. If you would like to read multiple words, the easiest is to read an entire line, e.g. … Read more
[ad_1] Unhandled exception at in ConsoleApplication1.exe: Microsoft C++ exception: std::invalid_argument at memory location [ad_2] solved Unhandled exception at in ConsoleApplication1.exe: Microsoft C++ exception: std::invalid_argument at memory location
[ad_1] In one case, you use size_t, in the other case you use int. If the length is for example 6 characters, then s.size () – 7 is not -1, but one huge number and everything goes wrong. But if you write int len = strlen (…), then len – 7 is indeed -1 and … Read more
[ad_1] The answer is “it depends”, or perhaps better put as “nobody knows”, as this type of question is always tightly coupled with compiler optimisations, processor architecture and many other factors. I would also like to point out that if you find one better on one system, it may not reflect that it’s better in … Read more
[ad_1] Let’s look at it line by line. int cin; This line declare a local variable named cin. From now on, whenever you write cin, the compiler always believe you mean this local variable, not the input stream object std::cin. cin >> cin; This line read the local variable and perform bit shifting. When both … Read more
[ad_1] Many thanks to Jdweng for providing a solution. I modified their code slightly so that it didn’t rely on making the datatable manually and instead took it from my SQLite database file. Jdweng’s code also made a ‘Root’ node which was not necessary for my application so I changed it to only include the … Read more
[ad_1] Change: for (int i = 0; i > cars.Count; i++) To: for (int i = 0; i < cars.Count; i++) [ad_2] solved Searching for a String in a text file
[ad_1] Note that “reachability” on IP networks is kind of tricky to test for. It’s perfectly possible that a server machine is running any number of real services (www, ftp, whatever), but has been configured not to reply to pings since some people do that. If possible, it’s better to just connect like the real … Read more
[ad_1] Since #define in C# is different from C and C++, you should use method call instead. private int xtime(int x) { return (x << 1) ^ (((x >> 7) & 1) * 0x1b); } [ad_2] solved What is the C# equivalent code for C programming statement? [closed]
[ad_1] It’s a reference to a pointer: CheckList(Listfile*& Listitems,bool showSortList) ^^^^^^^^^ pointer to Listfile ^ reference you should study C++ better, this can be found in any decent C++ book. 2 [ad_2] solved Can not understand the return of this function in C++
[ad_1] You can use the Tag property of each control. So set it to something meaningful and on Click event do something like this: (sender As Control).Tag EDIT: Also you may do this: foreach (Control item in this.Controls) //this IS YOUR CURRENT FORM { if ((sender as Control).Equals(item)) { //Do what you want } } … Read more
[ad_1] Code Review: You open the input file in main and open it again in your count_word function. You may get errors from the operating system stating that the file is already open. A good idea is to close a file before opening it again, or pass the file pointer to the function. You could … Read more
[ad_1] The second example has a memory leak. If what you want is just a “fill” function then setOfVertices.insert(setOfVertices.end(), 10, Vertex()); is good enough. However, if what you want instead is insert different Vertex objects then // Make sure only a single memory allocation takes place. setOfVertices.reserve(setOfVertices.size() + 10); for (int i = 0; i … Read more
