stcuct和class的区别

1struct的成员默认权限是public，而class的成员默认权限是private。

#include <iostream>int main(){class A{public: int a;};    struct B     {public:int a;    }; A A1; B B1; B1.a = 0; A1.a = 0; return 0;}

2.struct的默认继承方式为public，而class的默认继承为private

#include <iostream>int main(){class A{public: int a;};    struct B     {public:int a;    };class A1:A{};struct B1:B{};B1 B2;A1 A2;A2.a = 0;B2.a = 0; return 0;}
