But in C++ this 'freedom of variable placement' is based on a
performance consideration. Imagine you have three or four pretty
complex classes, with pretty complex contructors. Now there's
a function in your code where you need to use instances of all
those classes.
In C style you would declare them all at the beginning...but that
would also include the costs of constructions for your classes...
...whereas if you declare them where you actually need them you
only have those costs if you need those costs.
However, I think it was Stroustroup who said, that with C++
you can shoot your foot off...he's right. C++ offers great freedom,
in *any* aspect (both in coding paradigm (OOP vs. structured etc)
but also in personal coding style). Take the wrong turn, you can
wave bye bye to your foot ;)
