auto 自动类型推导以及注意事项

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++11
    static 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 m
    auto 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* p1
    auto* p2 = &n;  //同上

}
