    Help with getch();

    Why does getch(); have to get the character before it will output the cout<< before it???

    void displayalbum(NODE* &head,apstring &album)
    {
    NODE *node=head;
    int count=0;

    cout<<"\n";

    for(node;node;node=node->next)
    {
    if(node->album==album)
    {
    cout<<node->artist<<endl;
    cout<<" "<<node->album<<endl<<" Loaned : "<<node->loaned<<endl;

    if(node->loaned=="y")
    {
    cout<<" To : "<<node->towho<<endl;
    }

    cout<<"\n";

    count++;
    }
    }

    if(count==0)
    cout<<"* CD NOT FOUND *\n\n";

    cout<<"Press any key to continue.";
    getch();

    cout<<"\n";

    return;

    }
    <^>( * ; * )<^>

    try using _getch()
    -Save the whales. Collect the whole set.

    The problem you are having is because cout is buffered....

    cout<<'\n'; // this does not flush the buffer.

    cout<<endl; // this on the other hand will.

    to flush specifically without using a newline ....

    cout<<"Are you starting to get it??"<<flush;

    cout will also be flushed on any call to cin (providing you have not untied the streams).
    Free the weed!! Class B to class C is not good enough!!

    Try
    [/CODE]

    cout<<"Press any key to continue.Test" << endl << flush ;
    getch();
    [CODE]

    I think you just need to force (flush) the output.

    dang
