Golden Rule: Imitate the code from template.cpp and template.h, and what you see around.
Indentations: use ONLY white spaces. 1 indentation == 4 white spaces.
Comments: use multiline comments for multiline text and single line comments for single lines of text.
Names: use short names for simple things, long names for complex.
File Names: use lowercase characters and underscores (a-z and _) for names of .h and .cpp files.
