在C++中，结构和类基本相同。但也有一些细微的差别。这些差异如下所示。
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。
#include <iostream>
using namespace std;
class my_class {
int x = 10;
};
int main() {
my_class my_ob;
cout << my_ob.x;
}This program will not be compiled. It will generate compile time error for the private data member.
#include <iostream>
using namespace std;
struct my_struct {
int x = 10;
};
int main() {
my_struct my_ob;
cout << my_ob.x;
}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.
#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;
}This program will not be compiled. It will generate compile time error that the variable x of the base class is inaccessible
#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;
}10
