    Importance of static object in a class and how they are different from general object

    #include "B.h"
    class A
    {
    public :
    A()
    {
    s_b = new B();
    b = new B();
    }
    static B s_b ;
    B b ;
    };
    #include<iostream>
    using namespace std ;
    #include "A.h"
    int main()
    {
    cout<<"hello";
    }
    In my project i have seen static object as above . But not able to know what is the exact use of it and how they are different from general object . Please help me in finding out What all the things i can do with s_b which is not being done by b .

    Did you try to compile this?

    a static class member and a global object are pretty much the same from a generated code p.o.v.

    from a C++ p.o.v., one is a class member, and the other is not (well duh)
    meaning, you can make the class member public access, protected access of private access.

    the global object will be public access either only for the module (.cpp file) it's declared in, or it will be public access for all the modules in compilation.

    Short story: the only difference is that the static member is encapculated where the other (global) is not.
