This article mainly introduces "what are the basic principles of C++". In daily operation, I believe many people have doubts about what the basic principles of C++ are. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer your doubts about "what are the basic principles of C++?" Next, please follow the editor to study!

P: Philosophy (basic principles)

The rules in this section are very general.

The rules in this partition are general and universally applicable.

Philosophy rules summary:

A list of basic principles:

P.1: Express ideas directly in code

Express ideas directly in code

P.2: Write in ISO Standard C++

Write code using the ISO standard C++

P.3: Express intent

Interpretive intention

P.4: Ideally, a program should be statically type safe

Ideally, the program should be type-safe

P.5: Prefer compile-time checking to run-time checking

Compile-time checks are better than execution-time checks

P.6: What cannot be checked at compile time should be checkable at run time

Cannot be checked at compile time, it should be checked at execution time

P.7: Catch run-time errors early

Catch execution errors as early as possible

P.8: Don't leak any resources

No resource leaks.

P.9: Don't waste time or space

Don't waste time and space.

P.10: Prefer immutable data to mutable data

Immutable data is better than variable data.

P.11: Encapsulate messy constructs, rather than spreading through the code

Compress messy constructs instead of spreading them through code

P.12: Use supporting tools as appropriate

Proper use of support tools

P.13: Use support libraries as appropriate

Proper use of support libraries

Philosophical rules are generally not mechanically checkable. However, individual rules reflecting these philosophical themes are. Without a philosophical basis, the more concrete/specific/checkable rules lack rationale.

Basic principles are not usually mechanically inspectable. However, separate rules that reflect these basic principles are inspectable. Without basic principles as the basis, more specific / special / inspectable rules will lack basis.

Translator's note: the so-called mechanical inspection should refer to the use of inspection software to check through the rules.

At this point, the study of "what are the basic principles of C++" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
