The coding style is almost the same as i blackbox. Instead of 2 spaces there is tab. Use a tab size of 2 or 4 and you will be fine. if-statements: if ( stuff ) function(stuff, more stuff, more, even more); else morefunction( stuff, more stuff stuff, stuff, stuff); if the functionline needs to be split up, like above, right after an if-statement use {�and }, so its clear when the if-statement ends. It should look like this if ( stuff ) { function(stuff, more stuff, more, even more); } else { morefunction( stuff, more stuff stuff, stuff, stuff); } If a line need to be splited in an if-statement then it should use two tab for indent next row in if-statement like this: if ( longline && longline && longling && longline && longline && longline) funktion(); The include guards: FILENAME_HH Function comments: //------------ function name -------- // This do that and that // Returns this on success else // this on failure. // TODO: if there is something to do. //----------------------------------- type classname::function(...) { } enums must be in uppercase letters and not in file scope: enum {WHITE, RED, BLUE}; Class data members are prefixed by m_ Class member function will be organized accordning to creator, manipulator and accessor categories.
