Gathering general coding advises...

Question

Hi there,

the next exam is coming, starring C, CPP and Java.
Therefor i want to ask u, or the SoloLearn-Community for some general coding advises ... such as:

avoid type casting
using getter/setter
and so on ...

Are there any advises - no matter what language is used - to make programs more efficient?
Which classic Datatypes to use?
When to use pointer?

Lets gather all of these improving samples :)
