In C, function naming follows linguistic principles, including using verbs or verb phrases (such as calculateAverage()), avoiding semantic ambiguities (such as formatText is better than modifyText), providing sufficient context (such as calculateAverageOfStudents()), and using Pascal Nomenclature (such as GenerateStudentReport()).

Linguistic considerations of C function naming

In C, function naming is crucial because it can show To improve the readability and maintainability of the code. Follow linguistic principles to create clear, concise, and meaningful function names.

Linguistic principles

  • Use verbs or verb phrases: Function names should accurately describe what the function does, usually using verbs or verb phrases phrase. For example: calculateAverage(), displayMessage().
  • Avoid semantic ambiguity: Use clear names and avoid ambiguous or confusing words. For example: formatText is better than modifyText.
  • Provide sufficient context: Function names should contain enough information for the reader to understand what the function does without having to refer to the function documentation. For example: calculateAverageOfStudents().
  • Use Pascal nomenclature: For multi-word names, use Pascal nomenclature (the first letter of each word is capitalized). For example: GenerateStudentReport().

Practical case

The following are some examples of C function naming that follow linguistic principles:

  • Computing students Average score: double calculateStudentAverage(const vector& scores)
  • Display message on the screen: void displayMessage(const string& message)
  • Format text into HTML:string formatTextForHTML(const string& text)
  • Generate student report :string generateStudentReport(const Student& student)

Errors to avoid

  • Use ambiguity Clear names: doSomething(), process().
  • Put context into comments: calculateAverage(**description of the set of numbers**).
  • Extensive use of abbreviations: calcAvg(), dispMsg().
  • Use Hungarian nomenclature: Add a type prefix (such as iNum, sName) in front of the variable name.

By following these linguistic principles, you can create clear, meaningful C function names that improve code quality and maintainability.
