Switch files and convert the second include to <>, as other suggested. #include "stdafx.h" #include See this post for more information. share|improve this answer answered May 31 '13 at 13:53 Matthieu Rouget 2,026720 1 thx, I just found that out by myself, but you are the only one with the actual fix :D :D –Dekay May 31 '13 at 13:57 @user2440586, To be fair, it is a lot better to use angle brackets when including standard headers. –chris May 31 '13 at 14:04 add a comment| up vote 11 down vote First of all: #include instead of #inclu

Restrict using directives to small scopes, for example #include inline void foo() { using std::cout; using std::endl; cout << "Hello world" << endl; } Here, the using directive only applies to the scope of foo(). shar

Posted 09 March 2010 - 05:32 AM I am going through a tutorial in a book. At the end of the tutorial they give you some example source code. I copied the source code down word for word. Since I am using the visual c++ 2008 express edition compiler I added #include "stdafx.h". When I try to compile the program I get the error Cout is an undeclared identifier. Anyone know how I can fix this? I tried creating a new project without the precompileed header option checked but it still isnt working. source // Magic Number Game.cpp : Defines the entry point for the console application. // #include #include #include "stdafx.h" int _tmain(int argc, _TCHAR* argv[]) { int magic; int guess; magic = rand(); cout << "Enter your guess: "; cin >> guess; if (guess == magic) { cout << "** Right **\n"; cout << magic << " is the right number.\n"; } else { cout << "...Sorry, you're wrong."; //use a nesed if statement if(guess > magic) cout <<" You're guess is too high.\n"; else cout << " You're guess is too low.\n"; } return 0; } errors 1>------ Build started: Project: magic number game 2, Configuration: Debug Win32 ------ 1>Compiling... 1>stdafx.cpp 1>magic number game 2.cpp 1>(16) : error C2065: 'cout' : undeclared identifier 1>(17) : error C2065: 'cin' : undeclared identifier 1>(20) : error C2065: 'cout' : undeclared identifier 1>(21) : error C2065: 'cout' : undeclared identifier 1>(24) : error C2065: 'cout' : undeclared identifier 1>(28) : error C2065: 'cout' : undeclared identifier 1>(30) : error C2065: 'cout' : undeclared identifier 1>Generating Code... 1>magic number game 2 - 7
