Update main.cpp

[Brooksey24]

First thanks for the tutorials so far! Brand new here so just finding any reason to get into code. Both bytes_read and bytes_written seem to be unnecessary variables as the documentation specifies NULL is usable in this instance. Figured it might help reduce complexity to newcomers like myself.

Thanks for the suggestion and glad you are enjoying the tutorials! I vaguely remember at one point in the past (Windows 7-era) that ReadProcessMemory & WriteProcessMemory would fail in certain situations if not provided with a lpNumberOfBytesRead parameter. However, when looking at the MSDN documentation, this is apparently not the case.

Let me investigate this a bit. If it turns out the parameter is unneeded in all cases, I'll drop it and update all the code.

Thought there would be a good reason. Cheers for giving an explanation! I'll try give you more feedback for further tutorials (after studying a bit more C++ XD)
