What are the notations (naming rules) in programming?

Question

Programming

I met two types of notation:
- camelCase;
- under_score.
Based on the above I saw combinations of styles .
Pros and cons , as I understand it - this is a purely personal matter (individual, company). What are you using? I will use the corrected style tomorrow, based on the source .
I've been learning programming for a couple of months. Now in Java I use the following conventions:
1. variable int iValue = 0;(I put the first symbol of the type in the prefix);
2. instance variable int m_iValue = 0;(met in S.Prata 's book )
3. function/method: camelCase;
4. Grades: CamelCase;
5. objects: obj_jlabName = new JLabel();(something similar in the book atG. Schildt about Swing ).
Conclusion #1: Self-documenting code. Source - post and comments on this question.
Conclusion #2: Reading books like Perfect Code , Clean Code .

Answer 1

I don't see the point in modern IDEs with syntax highlighting, putting information about the type and class membership in the variable name.
-less gibberish
-more readability and self-commenting code

Answer 3

Briefly: Name so that the meaning of the variables (code) is clear not only to you.

Answer 4

points 1,2 and 5 are horror and the last century.

Answer 5

I've been learning programming for a couple of months.

I propose, for greater fruitfulness of the indicated discussion, to return to it ... in 10 years. ;-)
PS In the meantime, you study programming ...

Answer 6

Now in Java

Java has its own naming convention, like most languages. This is not a place for creativity or display of individuality.
