The rules a compiler applies to the source creates implicit standards. For example, Python code is much more consistently indented than, say Perl, because whitespace (indentation) is actually significant to the interpreter. Python does not use the brace syntax Perl uses to delimit functions. Changes in indentation serve as the delimiters.
[1] [2] Individual standards are offered for C, C++, Java, Android OS, and Perl. [ 3 ] Guidelines in the CERT C Secure Coding Standard are cross-referenced with several other standards including Common Weakness Enumeration (CWE) entries and MISRA .

A functional requirement in a functional specification might state as follows: When the user clicks the OK button, the dialog is closed and the focus is returned to the main window in the state it was in before this dialog was displayed. Such a requirement describes an interaction between an external agent (the user) and the software system ...
The ten rules are: [1] Avoid complex flow constructs, such as goto and recursion. All loops must have fixed bounds. This prevents runaway code. Avoid heap memory allocation. Restrict functions to a single printed page. Use a minimum of two runtime assertions per function. Restrict the scope of data to the smallest possible.
let {c_1 = 1; c_2 = 2} in f x y = c_1 * x + c_2 * y Haskell encourages the use of literate programming , where extended text explains the genesis of the code. In literate Haskell scripts (named with the lhs extension), everything is a comment except blocks marked as code.
In Python, if a name is intended to be "private", it is prefixed by one or two underscores. Private variables are enforced in Python only by convention. Names can also be suffixed with an underscore to prevent conflict with Python keywords. Prefixing with double underscores changes behaviour in classes with regard to name mangling.
Chapter 6.1 defines the purpose for the software verification process. DO-178C adds the following statement about the Executable Object Code: "The Executable Object Code satisfies the software requirements (that is, intended function), and provides confidence in the absence of unintended functionality."
