在QT程序中使用cout和cin

1先輸入10個數字，再輸出。

 

#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，此時的cout是不會在輸入之遙自動刷新緩沖區的
    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;
}
