Structures in C++ is a class where the default access is public unlike class where it is private. The default inheritence in structure is also public.
Mainly exists in C++ for backward compatibility with C.
You can use class whereever you want to use structure.
struct A
{
int x; // public by default
};
class A
{
int x; // private by default
};
struct B : A // public inheritence by default
{
};
class B : A // private inheritence by default
{
};
I hope you know what classes are?
