System("PAUSE")?

    Hi guys,

    I forgot that when programming in Visual Studio (in C) the exe will sometimes display on screen for a second before closing itself. I was giving a lab earlier and told them to use system("PAUSE"). I know it's not ideal. Now it worked on some machines and not on others (would I have to tell them to include stdlib.h?). I'm wondering is there an easy way to rectify this in VS?

    If not would some implementation of getchar() be better?

    Thanks (it's for beginners so I don't want to confuse them too much).

    getchar() is better.

    system("pause") will only work in windows.

    Thanks but OS dependent stuff is not really much of a concern at the moment (the course is through Visual Studio) and they are absolute beginners.

    Think I've found the answer though. I was showing them that after compiling and building the project to hit F5 (Start Debugging) to execute... Seems Ctrl+F5 (Start without Debugging) does the trick (leaving the output on screen).

    :o

    I can't believe it. D'oh! My first time giving a lab so I'm allowed a get out of jail free card.

    This is why teaching new students with a heavy professional IDE like Visual Studio is a Bad Idea™...

    Haha! You're right but it ain't up to me.

    Don't most Irish college's do it that way though?

    Wow, I've just started a thread on that subject. I think its because students like to see results up front.

    mine didn't.

    we were 3 years into a 4 year course before we were shown any IDE.

    If you have a solution to your original question can you change the thread to [Solved]? Thanks.

    VS is not a programing language. Have you tried Thread.Sleep(500) or similar?

    Well... this is a one year course. Better suited to the other thread methinks.
