默认情况下，类成员是私有的，但结构体的成员是公共的。让我们看看这两个代码，看看有什么不同。
示例#include <iostream>using namespace std;class my_class { int x = 10;};int main() { my_class my_ob; cout << my_ob.x;}
输出this program will not be compiled. it will generate compile time error forthe private data member.
示例#include <iostream>using namespace std;struct my_struct { int x = 10;};int main() { my_struct my_ob; cout << my_ob.x;}
输出10
when we derive a structure from a class or structure, the default access specifier of that base class is public, but when we deriving a class the default access specifier is private.
示例#include <iostream>using namespace std;class my_base_class { public: int x = 10;};class my_derived_class : my_base_class {};int main() { my_derived_class d; cout << d.x;}
输出this program will not be compiled. it will generate compile time error that the variable x of the base class is inaccessible
示例#include <iostream>using namespace std;class my_base_class { public: int x = 10;};struct my_derived_struct : my_base_class {};int main() { my_derived_struct d; cout << d.x;}
输出10
以上就是c/c++ 结构体与类的区别的详细内容。
