How can I see an the output of my C programs using Dev-C

Question

I m looking to follow along with The C Programming Language  Second Addition  on a machine running Vista   So far  I ve found Dev-C   the easiest IDE to do this in  However  I still have one problem  Whenever I run my compiled code  for example  a simple hello world program  it runs  but the console window just flickers on the screen  and I can t see the output   How can I see an the output of my C programs using Dev-C    I found a C   specific solution  System  pause    and a really ugly C solution  while looping fflush stdout   but nothing nice and pretty

You can open a command prompt  Start -  Run -  cmd  use the cd command to change directories  and call your program from there  or add a getchar   call at the end of the program  which will wait until you press Enter  In Windows  you can also use system  pause    which will display a  Press enter to continue      or something like that  message

Well when you are  writing a c program and want the output log to stay instead of flickering away you only need to import the stdlib h header file and type  system  PAUSE     at the place you want the output screen to halt Look at the example here The following simple c program prints the product of 5 and 6 i e 30 to the output window and halts the output window    include  lt stdio h gt   include  lt stdlib h gt  int main            int a b c        a 5 b 6        c a b        printf   d  c         system  PAUSE          return 0       Hope this helped

It works      include  lt iostream gt  using namespace std  int main         int x y      Or whatever variable you want you can    your required process syntax type here then      cout  lt  lt  result     or your required output result statement   use without space in getchar and other syntax      getchar        Now you can save your file with  cpp extension and use ctrl   f 9 to compile and then use ctrl   f 10 to execute the program  It will show you the output window and it will not vanish with a second Until you click enter to close the output window

When a program is not showing or displaying an output on the screen  using system  pause    is the solution to it on a Windows profile

For Dev-C    the bits you need to add are -  At the Beginning   include  lt stdlib h gt    And at the point you want it to stop - i e  before at the end of the program  but before the final    system  PAUSE      It will then ask you to  Press any key to continue

In Windows when a process terminates  the OS closes the associated window   This happens with all programs  and is generally desirable behaviour   but people never cease to be surprised when it happens to the ones they write themselves   I am being slightly harsh perhaps  many IDE s execute the user s process in a shell as a child process  so that it does not own the window so it won t close when the process terminates   Although this would be trivial  Dev-C   does not do that   Be aware that when Dev-C   was popular  this question appeard at least twice a day on Dev-C   s own forum on Sourceforge   For that reason the forum has a  Read First  thread that provides a suggested solution amongst solutions to many other common problems   You should read it here   Note that Dev-C   is somewhat old and no longer actively maintained   It suffers most significantly from an almost unusable and very limited debugger integration   Traffic on the Dev-C   forum has been dropping off since the release of VC   2005 Express  and is now down to a two or three posts a week rather than the 10 or so a day it had in 2005   All this suggest that you should consider an alternative tool IMO

i think you should link your project in console mode  just press Ctrl h and in General tab select console

User · Answer

The use of line system  PAUSE   will fix that problem and also include the pre processor directory  include lt stdlib h gt

I put a getchar   at the end of my programs as a simple  pause-method    Depending on your particular details  investigate getchar  getch  or getc

The easiest thing to do is to run your program directly instead of through the IDE   Open a command prompt  Start- Run- Cmd exe- Enter   cd to the folder where your project is  and run the program from there   That way  when the program exits  the prompt window sticks around and you can read all of the output   Alternatively  you can also re-direct standard output to a file  but that s probably not what you are going for here
