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.
To draw the Lewis dot structure for Al³⁺, start with the aluminum atom, which has three valence electrons. However, since Al³⁺ indicates that the aluminum has lost three electrons, it will have no dots around it in the Lewis structure. Therefore, the Lewis dot structure for Al³⁺ is simply represented as "Al³⁺" with no dots, indicating that there are no remaining valence electrons.
To draw a Lewis structure for Be2+, start by writing the symbol for beryllium. Since Be2+ has a 2+ charge, it has lost two electrons. Place the two electrons as individual dots around the beryllium symbol, as there is no other atom bonded to it. The Lewis structure for Be2+ is simply Be with two dots around it.

To describe the bonding in the cation PBr₄⁺, only one Lewis structure is necessary. In this structure, phosphorus (P) is the central atom surrounded by four bromine (Br) atoms, with a formal positive charge on the phosphorus due to the loss of one electron. This results in a tetrahedral geometry, and there are no resonance structures needed for PBr₄⁺, as the single Lewis structure adequately represents the bonding.

Two equivalent Lewis structures are necessary to describe the bonding in NH4+ because nitrogen in the ammonium ion has a full octet and can form a single coordinate covalent bond with each of the four hydrogen atoms, resulting in two resonance structures.

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.
Structures in C and C++ differ in that C structures do not have an automatic typdef associated with them.

I have a 1989 Browning Accelerator Plus and I was wanting to adjust the draw length?
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.
