C++ Conventions: this pointer

Question

I am curious to know, is there a convention to the usage of this-> in C++? I generally like to use this-> to emphasize that a method and/or variable is a member of the containing class, but it does look rather unappealing, visually speaking. It'd also be awesome to know about any other C++ coding conventions often seen in industry, e.g. Camel case vs. underscores, etc.

Thanks!

I personally avoid the this-> pointer whenever possible but that's just personal preference.

Coding conventions largely vary but one example is Google's comprehensive C++ Style guide.

• "Filenames should be all lowercase and can include underscores (_) or dashes (-)."
• "Variable names are all lowercase, with underscores between words. Class member variables have trailing underscores."
• "Regular functions have mixed case; accessors and mutators match the name of the variable"

And, my favorite:

• "You're not really going to define a macro, are you? If you do, they're like this: MY_MACRO_THAT_SCARES_SMALL_CHILDREN."
