It would look something like this
.. .. ..
: F ----Br -----F:
.. .. ..
There are 21 valence electrons in neutral BrF2, so there will be one unpaired. Draw each F having a shared pair, giving each F 8 electrons. The central Br atom will have 9 electrons.
If the charge is BrF2 there will only be 8 electrons around Br, if the charge is BrF2- then there will 10. BrF2+ is well known.

Mg2+
You mean balance it? 2C2H6 + 7O2 -> 4CO2 + 6H2O

Structures in C and C++ differ in that C structures do not have an automatic typdef associated with them.
Sorry, it's impossible to draw with a keyboard!
Download and install the WinBGIM Devpack. Once installed, you can include graphics.h to draw graphics.

Mg2+ is (theoretically speaking) a Lewis acid, but I don't know how strong.
The Lewis structure of CH3 starts with a C in the center, representing the Carbon atom. The carbon atom has three dashes and two dots. Connected to each dash is an H, representing the hydrogen atoms.
yes
2 dots
Put their names into the parameter-list.
As far as C++ is concerned files do not have structures, they are simply raw data streams. It's entirely down to the programmer to determine what structures exist within the file and to interpret the data accordingly. C++ cannot do it for you.
