I found a webpage which explains MakeFiles and I am following their directions. http://mrbook.org/tutorials/make/ I downloaded the four example files into their own directory. main.cpp hello.cpp factorial.cpp functions.h I then went ahead and ran their example of how to manually compile without a MakeFile. g ++ main . cpp hello . cpp factorial . cpp - o hello When I ran the command from above, I received the

Then ... C[ler] is assigned to B[ler/2][2]. Those coordinates, per row, in B[ler/2][2] are assign to a and b. a and b are the row and the column of the matrix A[tm][tm] where to add 1.

The following code was compiled with VC++ Nov 2012 CTP on Windows 7 x64. #include <fstream> using namespace std; int main() { ofstream fout("log.txt", ios::app|ios::trunc); if (!fout) { cout << "An error occurred!" << endl; // Always go here! Why? } } The cppreference.com website doesn't say that ios::app cannot be combined with ios::trunc . What are the exact semantics of ios::app and ios::trunc ? The filebuf constructor to which these flags are passed † has behaviours based on those flags defined in Table 132 in C++11: +-----------------------------------+-------------------+ | ios_base flag

Is there a way to print colored output using iostream and Xcode? I'd like to be able to, for example, print Hello World! with Hello red, World blue and ! yellow. How can I do that? shuttle87 You need the terminal color codes. For linux it's the following (your system might be different, look it up): //the following are UBUNTU/LINUX, and MacOS ONLY terminal color codes. #define RESET "\033[0m" #define BLACK "\033[30m" /* Black */ #define RED "\033[31m" /* Red */ #define GREEN "\033[32m" /* Green */ #define YELLOW "\033[33m" /* Yellow */ #define BLUE "\033[34m" /* Blue */ #define MAGENTA "\033

I'm trying to make an iOS 5 app that features real-time things coming from the server. It will only use these whilst the app is running. To make it real-time without polling I have been evaluating two design routes: Creating a socket from the app to the server, and exchanging information via streams. Pros: Relatively simple and would not involve a 3rd party. Cons: Battery life drain. For an overview of how this might work, check out this excellent tutorial: http://www.raywenderlich.com/3932/how-to-create-a-socket-based-iphone-app-and-server Using standard HTTP to communicate with the server,
