Does the both object point to the same value in copy constructor

Foo(const  Container& obj);   // Copy Constructor

Foo::Foo(const Container& obj) : Geom (obj.Geom)  {
 // Assign Values In Constructor
  stdstrContainerName = obj.stdstrContainerName;
  stdstrPluginType = obj.stdstrPluginType;  
}

Foo fooToCopy;
 Foo foo;
 foo = fooToCopy;

1) Since i am using pass by reference do the foo and fooToCopy point to the same variable

2) If fooToCopy goes out of scope before foo than will the variable value be destroyed.
