#include<QtCore/QCoreApplication>
#include<QDebug>
int main(int argc,char *argv[]){
QCoreApplication a(argc,argv);
qDebug() << "hello world";
return a.exec();
}
2.控制台输出 helloworld(QString应用)
#include<QtCore/QCoreApplication>
#include<QDebug>
int main(int argc,char *argv[]){
QCoreApplication a(argc,argv);
QString mStr="hellowlrd";
