auto 自动类型推导以及注意事项

#include <iostream>
using namespace std;struct Student {int age = 18;//auto num = 20; //不允许//C++11static const auto num = 0;//C++17//static inline auto number = 0;  
};void main(){int n = 100;//auto 自动类型推到auto m = 50; //如同int mauto m = 50.0;  //如同float m//auto p1 = &n, k = 5; //k推到时被干扰auto p1 = &n; //如同int* p1auto* p2 = &n;  //同上}
