为何输入姓名后要按两下回车才有结果？

Question

#include <iostream>#include <string>#include <stdlib.h>using namespace std;int main(){string name;cout<<"请输入姓名:";getline(cin,name);if(name.empty()){cout<<"输入为空"<<endl;system("pause");return 0;}if(name == "imooc"){cout<<"you are a administrator"<<endl;}cout<<"hello "+ name<<endl;cout<<"名字首字母是："<<name[0]<<endl;cout<<"名字的长度是："<<name.size()<<endl;system("pause");return 0;}为何结果后面“请按任意键继续”回车后又会有“press any key to continue ”

Answer 1

你不是调用了system("pause")吗？这句话就是这个作业。
