What are real programming conventions I have heard different things and seen different things so is there none at all? I know style varies between individuals and development teams but there are definite trends. For example:
pointers, which of these do people generally follow?
and when using operator overloading I was told that if the operator has no side effects it should be a friend function, else it should be a member function. Is this true?
What other conventiosn are there? And which do you follow?
