error in declaring the class type variable

#include <iostream>
using namespace std;
class A{
private:
    int x;
public:
    A(){
        x=0;
    }
    A(int i)
    {
        x=i;
    }
    int Get_x(){
        return x;
    }
};
class B{
    private:
    A objA(1);
    public:
    objA.Get_x();   
};

This is my code and it has two classes i.e A and B ..First class runs fine but in class B ..compiler gives the syntax error in the declaration of objB.....But as far as i know it should be correct ...so plz help ....thanks

The compiler is trying to interpret A objA(1) as a function declaration, which is wrong. You may declare objA as A objA = A(1); (please note that thi is a C++11 feature, you may need to enable it before).

Also, I don't really know what objA.Get_x() should do, but this is also wrong, you can't just access a member outside of a function. Probably, you meant this: 

int Get_x() {
    return objA.Get_x();
}

This initialization is invalid for a data member:

A objA(1);

You need 

A objA{1};

or

A objA = A(1);

Besides that, this kind of statement can only happen inside of a function:

objA.Get_x();
