在QT程序中使用cout和cin

#include <QtCore/QCoreApplication>  
#include <QtCore/QList>  
#include <QTextStream>  
int main(int argc, char *argv[])  
{  
    QCoreApplication app(argc, argv);  
    QTextStream cin(stdin, QIODevice::ReadOnly);   
    QTextStream cout(stdout, QIODevice::WriteOnly);    
    QList<int> list;  
    cout << "Please enter ten numbers: ";  
    //注意，此时的cout是不会在输入之遥自动刷新缓冲区的  
    cout.flush();  
    for(int i=0; i<10; i++)  
    {  
        int temp;  
        cin >> temp;  
        list.push_back(temp);  
    }  
    QList<int>::iterator iter;  
    for(iter=list.begin();iter!=list.end();iter++)  
        cout << *iter << " ";  
    cout << endl;  
    return 0;  
}
