int static length_ = 2;
};
會(huì)報(bào)錯(cuò)non-const static data member must be initialized out of line
解決方法：
solu-1： 把此靜態(tài)成員變量加設(shè)為const
solu-1-eg.
#include <iostream>
class Cube
{
const?int static length_ = 2;
};
solu-2：把次靜態(tài)成員變量放到類外定義
solu-2-eg.
#include <iostream>
int static length_ = 2;
class Cube
{
};
