输入以下代码后,我会收到错误.

const int quantity;
cout << "How much spacing do you want in-between the frames? " ;
cin >> quantity;

错误:未初始化的const'数量'[ - fpermissive]

错误:'operator >>的模糊重载

如果我只使用int类型,就不会发生这种情况

int quantity;
cout << "How much spacing do you want in-between the frames? " ;
cin >> quantity;

哪个编译没有问题.我是C++的新手,所以我想知道为什么会这样.
