    Dev- C++

    Hi all,

    Im having a bit of problem with Dev-C++. When i run a dos program i have to use the system("pause") command, to stop the dos screen flashing up fast and then vanishing - this was fine when my programs were simple. However now my programs are getting more complex( running command line applications), its getting a real pain using the pause command.

    Therefore could somebody offer me some advice on how to change the compilers configuration options to enable me not to use the system("pause") .

    Cheers

    Just run your program from the command line. With the command prompt window open, you will not have this problem of "the dos screen flashing up fast and then vanishing".

    Hi,

    Thanks for speedy reply.

    Im dont really understand how to do that, currently i do the following:

    Open Dev-C++ >> open project >> run my program >> dos screen flashes up

    ????

    Look forward to your advice.

    cin.get();

    1. Start -> Run -> Open cmd. The command prompt window appears.

    2. Using the command prompt, navigate to your project directory.
    For example,
    cd C:\projects\xyz

    3. Enter your program name at the command line to run the program.

    If you really do not want to run your program like this (or redirect output to a file), then you have no choice but to live with system("pause") or one of the better suggestions from our FAQ.

    Oh wait, our FAQ needs to be updated because Prelude pointed out that in.clear() is not guaranteed to work as expected. From what I see, you can just remove in.clear() from myflush() in the C++ example.

    Select "Start" menu >> "Programs" >> "Accessories" >> "Command Prompt"

    In the black box that opens navigate to the directory where your exe is located using "cd" (change directory) command and type the name of your program to launch it.

    You can also create a shortcut to "Command Prompt" and configure it to start from desired directory.

    system("Pause") or cin.get are not very helpful if your program aborts because of an assert etc.
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.

    Hi again.

    I have followed your steps and i have a few questions:

    1) how to i create a shortcut to the path entered on the command line?

    2) is the path entered on the command line the same as creating a shortcut to the exe in the project folder (from windows desktop)?

    Cheers Tuurbo46

    Is there a reason you need to use Dev-C++?

    Hi,

    In a round about way, im a embedded c programmer and im learning dos c and c++ to improve my skill etc. After reading the cprogramming site they recommend Dev-C++ so this is what i use.

    Apart from the above reason no not really, what do you recommend?

    Cheers Tuurbo46

    There's Visual Studio Express. Terrific IDE IMO.

    You mean CLI-type, no? A dos window within <insert favorite OS here>?
    Pretty much all compilers can do that.
    Yes, I mean 2008. It can do both C and C++, if you want.
    Btw, I meant IDE, not GUI. It's a dev environment, debugger and compiler.

    Sure, Express is free, so go ahead if you want.
