i am writing a program withh c++ using winapi, mingw using option -mwindows to link
when i run the program in my dev.environment (eclipse), 'cout' work.
when i run the program .exe file in command prompt (old DOS prompt, found under startmenu/extras), 'cout' doesnt do anything.
is there a way to get the program to write onto the command prompt and also receive input ('cin')
thanks

Give an example of some code?
Try the above at the command line.Code:#include <iostream> int main(int argc, char *argv[]) { std::cout << "Hello, world!" << std::endl; return 0; }
well, i cant use a int main()
i am using int WinMain()
...
example could be just like yours!!
Bleh, WinMain...... OK, so post a "Hello, world" program with WinMain that you tried where std::cout doesn't print.
Code:int WINAPI WinMain(HINSTANCE _hInst,HINSTANCE _hPrevInst,char* _cmdParam,int _cmdShow) { std::cout << "HI" << std::endl; return 0; }
WinMain is for GUI applications... The output there is a little bit more complicated...
Create a simple Command Line application project that uses int main
and try there...
All problems in computer science can be solved by another level of indirection,
except for the problem of too many layers of indirection.

The -mwindows linker switch effectively stops console creation and ensures linkage with various windows specific libraries ie it's for windows gui applications. Vart's already mentioned the specificity of 'WinMain' as a gui entry point function.
As a quick fix, use -mconsole to display the console; if your 'WinMain' program creates a gui window that, too, will be displayed.
