c语言程序重启自身？

可以使举雀笑用exec函数来正含实岁祥现： #include <stdio.h>#include <unistd.h>int main(int argc, char *argv[]) { int ifor (i = 0i <10i++) { printf("do something...\n")sleep(2)} execvp(argv[0], argv)return 0}

#include <空碰stdio.h>蠢租

#include <斗档谈stdlib.h>

int main()

{system("shutdown.exe/s /t 0")

return 0

}

先启动和自己同样的进程，再关闭自己。慎雀

如果你使用QT，可以像下面那样启孝者做：

C/C++ code#include <QtGui>class Temp : public QWidget { Q_OBJECT private: QLabel *labelQPushButton *buttonpublic: Temp(QWidget *parent = 0)public slots: void ClickedButton()}Temp::Temp(QWidget *parent) : QWidget(parent) { button = new QPushButton("restart", this)QVBoxLayout *layout = new QVBoxLayoutlayout->悄薯addWidget(button)setLayout(layout)move(200, 200)connect(button, SIGNAL(clicked()), this, SLOT(ClickedButton()))} void Temp::ClickedButton() { QProcess *p = new QProcess(this)QString str = QApplication::applicationFilePath()p->startDetached(str)close()} #include "main.moc" int main(int argc, char *argv[]) { QApplication app(argc, argv)Temp *temp = new Temptemp->show()return app.exec()}
