    Another simple question

    Hi,

    cout << "Love one another";
    cin.get();

    -Prelude
    My best code is written with the delete key.

    ...........

    getch(); // waits for any key being pressed

    ............

    #include <stdlib.h>

    system("pause");

    // print to the screen "Press any key to continue..." and waits for user's input....

    >getch(); // waits for any key being pressed
    Nonstandard, may not work on all implementations and a bad idea in general to use unless you have to.

    >system("pause");
    To my knowledge this only works on DOS and Windows systems, and the system function is godawful slow.

    while (!kbhit()); should also work, but I believe it's nonstandard as well.

    BTW getch() will continue if the user presses any key at all. To check for enter being pressed, try:

    while (getch() != 13);

    Here's a standard way...


    Code:
    char wait;
    cin>>wait;

    The fastest too

    Yeah but you could gunk up your buffer doing that.

    another quick question:

    I don't remember exactly, but once upon a time I heard that "cout" outputs to a buffer. I was wonder if there is a command to purge that buffer (i.e. to display the text in that buffer immediately). I'm having timing problems with the getin() and system("pause").

    cout << "WASABI";
    getin() // or system(pause)

    my program would pause first, then when i press enter,..."WASABI" would then print (not good :[)
