Preventing console window from closing on Visual Studio C C Console application

Question

This is a probably an embarasing question as no doubt the answer is blindingly obvious   I ve used Visual Studio for years  but this is the first time I ve done any  Console Application  development   When I run my application the console window pops up  the program output appears and then the window closes as the application exits   Is there a way to either keep it open until I have checked the output  or view the results after the window has closed

You could run your executable from a command prompt  This way you could see all the output  Or  you could do something like this   int a   0  scanf   d   amp a    return YOUR MAIN CODE    and this way the window would not close until you enter data for the a variable

Here s a solution that  1  doesn t require any code changes or breakpoints  and  2  pauses after program termination so that you can see everything that was printed   It will pause after either F5 or Ctrl F5   The major downside is that on VS2013 Express  as tested   it doesn t load symbols  so debugging is very restricted    Create a batch file   I called mine runthenpause bat  with the following contents    1  2  3  4  5  6  7  8  9 pause   The first line will run whatever command you provide and up to eight arguments   The second line will    pause  Open the project properties   Configuration properties   Debugging  Change  Command Arguments  to   TargetPath   or whatever is in  Command    Change  Command  to the full path to runthenpause bat  Hit OK    Now  when you run  runthenpause bat will launch your application  and after your application has terminated  will pause for you to see the console output   I will post an update if I figure out how to get the symbols loaded   I tried  Z7 per this but without success

Just press CNTRL   F5 to open it in an external command line window  Visual Studio does not have control over it    If this doesn t work then add the following to the end of your code   Console WriteLine  Press any key to exit       Console ReadKey      This wait for you to press a key to close the terminal window once the code has reached the end   If you want to do this in multiple places  put the above code in a method  e g  private void Pause    and call Pause   whenever a program reaches a possible end

Currently there is no way to do this with apps running in WSL2  However there are two work-arounds   The debug window retains the contents of the WSL shell window that closed   The window remains open if your application returns a non-zero return code  so you could return non-zero in debug builds for example

A somewhat better solution   atexit      system  PAUSE          at the beginning of your program   Pros    can use std  exit   can have multiple returns from main you can run your program under the debugger IDE independent    OS independent if you use the cin sync    cin ignore    trick instead of system  pause       Cons    have to modify code won t pause on std  terminate   will still happen in your program outside of the IDE debugger session  you can prevent this under Windows using      extern  C  int   stdcall IsDebuggerPresent void   int main int argc  char   argv        if  IsDebuggerPresent            atexit     system  PAUSE

Here is a way for C C      include  lt stdlib h gt    ifdef  WIN32      define WINPAUSE system  pause    endif   Put this at the top of your program  and IF it is on a Windows system   ifdef  WIN32   then it will create a macro called WINPAUSE  Whenever you want your program to pause  call WINPAUSE  and it will pause the program  using the DOS command  For other systems like Unix Linux  the console should not quit on program exit anyway

SUBSYSTEM CONSOLE  did not worked for my vs2013  I already had it     run without debugging  is not an options  since I do not want to switch between debugging and seeing output   I ended with  int main            if  DEBUG   LOG INFO  end  press key to close      getchar     endif     DEBUG   return 0      Solution used in qtcreator pre 2 6  Now while qt is growing  vs is going other way  As I remember  in vs2008 we did not need such tricks
