VS里的绿色波浪线需不需要修改？
程序代码：#include<iostream>
#include<string>
using namespace std;
struct Jg{string Xingming; double Qian;};
int main() {
int Zongshu;
cout << "总共有多少名捐赠者？";
cin >> Zongshu; cin.get();
Jg* a = new Jg[Zongshu];
for (int i = 0; i < Zongshu; i++) {
cout << "请输入捐赠者姓名：";
getline(cin, a[i].Xingming);
cout << "请输入捐赠金额（单位/元）：";
cin >> a[i].Qian;
cin.get();
}
bool You_1 = false;
bool You_2 = false;
cout << "Grand Patrons：" << endl;
for (int i = 0; i < Zongshu; i++)
if (a[i].Qian > 10000) {
cout << "姓名：" << a[i].Xingming << endl;
cout << "金额：" << a[i].Qian << endl;
You_1 = true;
}
if (You_1 == false)cout << "none" << endl;
cout << "Patrons：" << endl;
for (int i = 0; i < Zongshu; i++)
if (a[i].Qian < 10000) {
cout << "姓名：" << a[i].Xingming << endl;
cout << "金额：" << a[i].Qian << endl;
You_2 = true;
}
if(You_2==false)cout << "none" << endl;
delete [] a;
system("pause");
return 0;
}在第4行代码struct Jg{string Xingming; double Qian;};有绿色波浪，提示为未初始化变量 Jg::Qian。始终初始化成员变量(type.6)。
程序能正常运行，想问下这个提示是什么意思，是说我没给Qian这个变量赋值么？一般什么情况下会出现这种现象？
