access an object

[mar11]

Hi,

Assuming, i have the following code..

//obj1

class obj1{ 
obj1();
void foo();
.......
};
// file1.cpp

int main{
...
obj1 Ob;
.....
} 

//file2

class obj2{ 
obj2();
.......
};

//file3

class obj3{ 
obj3();
.........
};

my question is, how can i access the instance 'Ob' in the main.cpp from the constructor of ther classes without instancing them in the main file. Something like that:

class obj3{ 
obj3();
.........
};
obj3::obj3(){

Ob.foo();  // how can i implement it
}

please help

thanks

You need to pass the object as a parameter to the constructor.
