#include<iostream.h>
class { public : int x; }a; //a is the object of this class

int main(){

a.x=10;
cout<<"a="<<a.x;
return 0;

}

Execute the above code one can get to know about class without name.

Nice discussion its possible blindly to create a name less class.

But my compiler reports an error.

If you create class but not having any name, gives compilation error. So I think answer C is right.

As said above, I have written the below code,

#include

Class
{
public :
int x;
}a; //a is the object of this class.

int main ()
{

A. X=10;.

Cout<<"a="<
Return (0) ;

}

It is giving me warning in the same compiler given here "Online C++ Compiler",

"Line 3: warning: non-local variable a' uses anonymous type".

@Aarti

Your code is quite wrong, are you trying to access x data member of the nameless class?

Use this code.

#include <iostream>
using namespace std;
class
{
public :
int x;
}a; //a is the object of this class.

int main ()
{
a.x=10;
cout<<a.x;
return (0) ;
}

Use this code.

#include <iostream>
using namespace std;
class
{
public :
int x;
}a; //a is the object of this class.

int main ()
{
a.x=10;
cout<<a.x;
return (0) ;
}

This code provides warning but gives output.

@All.

As per my knowledge.

#include<iostream>
using namespace std;
class
{
public:
void aa()
{
cout<<"aryan"<<endl;
}
}a;
int main()
{
a.aa();
return 0;
}
