You need two nested foreach loops. One iterates the ebles the inner one the elements in each list. The innermost loop contains a yield return element; This is the outline. Now go and read about each of the words mentioned in this outline. solved C# Enumerable yield and foreach [closed]
A working variation of my solution appears below. The reason I had to do it this way is because while I was able to dereference (**Array)[MAX_FILENAME_AND_PATHNAME_LEN] I was only able to modify the first string array in the array. The string array was initialized and filled several strings. While I could reference a string contained … Read more
It means, add 10 to arr[n-1], then add the new arr[n-1] value to arr[0]. 1 solved What is the use of equal sign two times in a statement
As a non-admin, you can only set something to startup automatically for your own user account. You would use the per-user startup folder (or one of the HKCU registry keys) for this. FOLDERID_CommonStartup For all users, requires admin privileges to modify. Location depends on OS version and customization, but by default is either: %ALLUSERSPROFILE%\Microsoft\Windows\Start Menu\Programs\StartUp … Read more
All expressions like ++a / b * b– – a have undefined behavior because variables are read from and written to without a sequence point in between. solved Why C++ operation priority is different when dealing with objects or primitive types ++a*b/b– – a [duplicate]
You can define an abstract class with “default” behavior by declaring a method as virtual and overriding it in derived classes. A derived class is not forced to override a virtual method in an abstract base class. If the method is not overridden, the behavior defined in the abstract class is used. Overriding the method … Read more
There is none. Once the array-to-pointer conversion happens, the size information is gone. If you need it, you have to pass the size as a separate argument. Since pArr is a pointer, sizeof(pArr) gives the size of the pointer. Your pointers seem to be double the size of ints; that is the case on x86-64, … Read more
Let’s split this into parts: $ is a character indicating that the shell is ready to receive a command. It is not part of the command. gcc is an executable executing the GNU C compiler from the GCC toolchain. test.c -o demo are arguments supplied to gcc. The GCC toolchain is only available natively for … Read more
Your condition should be while (a != ‘e’ && a != ‘r’) Otherwise it is always true no matter what value of a you enter. 6 solved Loop not doing its job
very probably a reasonable definition of cities (which was much better named City, no reason so have it plural) is typedef struct cities { char name[64]; struct cities * e; struct cities * n; struct cities * s; struct cities * w; } cities; and your problem is to write all the links without entering … Read more
You will want to do the following: char *gg = “hello”; printf( “%c\n”, gg[3] ); This will print the fourth character (zero based array = 0, 1, 2, 3 so 0=’h’, 1=’e’, etc). Change the 3 to which ever character you want, but make sure to not go past the end of the string. strlen … Read more

File-handling is all fairly new to me but, this is how I’ve done it in a recent MVC project. ImageController: this is how I’m saving the file public ActionResult Create(FormCollection collection) { if (ModelState.IsValid) { HttpPostedFileBase file = Request.Files[“userUploadedFile”]; var userName = User.Identity.Name; var selectAlbum = Request.Form[“lstAlbums”]; Image img = new Image(); img.FileName = file.FileName; … Read more
You can reformulate the question y = sqrt(x) as to find the value for y such that y*y – x equals zero. The easiest way to solve that equation is by doing a bisection on y (http://en.wikipedia.org/wiki/Bisection_method) between 0 and x (because 0 <= sqrt(x) <= x for all real numbers x where x should … Read more
