有大佬可以帮忙看看为什么这个程序运行不了结果(只是成功跳出了运行屏)😭😭🙏🙏

vector的用法跟数组不一样，你的代码中在录入数据的时候，都是for (int i = 0; i < message.size(); i++){cin>>message.at(i).sign_time_year;/**/}这种形式，此时message.size()的大小是0，不会往vector中插入数据的。
你的代码写的太乱了。
Volunteer_service类继承了information类，Volunteer_service类中定义的私有成员也没有使用。搞不懂你要干啥。
代码整理了一下，做个参考吧。

回复即采纳!孩子急求🙏🙏
首先，解决编译错误。
Volunteer_service::Act_time” :
Volunteer_service::Sign_time” :
Volunteer_service::Off_signtime” :
Volunteer_service::Sumofpeople” :
Volunteer_service::Off_acttime” :
Volunteer_service::Sumofservetime” :
还有main函数
//必须返回一个值
其次，编译了之后
int main()
{
Volunteer_service u;
for (int i = 0; i < people.size(); i++)
{
people.at(i).setxinxi();
}
}
此处的Volunteer_service u没有调用任何函数
此时people.size()=0，因为vector并没有加入数据。
