问题 I want to convert an int to a string so can cout it. This code is not working as expected: for (int i = 1; i<1000000, i++;) { cout << "testing: " + i; } 回答1: You should do this in the following way - for (int i = 1; i<1000000, i++;) { cout << "testing: "<<i<<endl; } The << operator will take care of printing the values appropriately. If you still want to know how to convert an integer to string, then the following is the way to do it using the stringstream - #include <iostream> #include

问题 Is there any human-editable configuration file that Visual Studio uses for its key bindings? The Options->Environment->Keyboard dialog is so completely broken (or at least much too tedious to use) and has been since Visual C++ 5 that I really just want to go to the configuration file the Visual Studio is saving the keybindings to and edit that directly. Ideas? 回答1: Not the most ideal format, but there is the currentsettings.vssettings file located in your profile. There is a section that

问题 Edit: im now using http://code.google.com/p/jpeg-compressor/ so i dont care about making this work anymore. I downloaded the http://ijg.org/ source code, i tried to build it as a DLL file. This is farthest i could build until i went into dead-end. I noticed there was some .c files which i had to delete, but i dont know if i deleted the correct ones, there was at least these files jmemmac.c and jmemdos.c which i figured i dont need. I had to delete jmemmac.c because i compile on windows, but
