Detailed explanation of C++ function naming: Questions and answers on following specifications and improving readability

C Function naming convention follows camel case naming or Pascal naming. It is recommended to use descriptive, concise function names that avoid abbreviations and special characters. Overloaded functions can be distinguished by differentiating parameters, using suffixes, or namespaces. Function naming conventions that have single-letter names, are ambiguous, are overly specific, or contain special characters should be avoided.

Detailed explanation of C function naming: Q&A on following specifications and improving readability

Function naming is an important style in C programming guidelines as it affects code readability and maintainability. Following clear naming conventions ensures your codebase is consistent and easy to understand.

Q1: What are the naming conventions for C functions?

• Camel case nomenclature: Compound words are named with camel case, such as IsValidInput()
• Pascal nomenclature: Compound words are named with camel case Pascal naming, such as IsValidInput
• Snake case: Compound words are connected with underscores, such as is_valid_input()
• Hungarian nomenclature: The prefix of the variable name indicates the data Type, for example iIsValidInput represents the integer IsValidInput()

It is recommended to use camel case nomenclature or Pascal nomenclature.

Q2: How to choose meaningful and concise function names?

• Descriptive: The function name should accurately describe the function and purpose of the function.
• Conciseness: Function names should be as concise as possible without losing clarity.
• Avoid abbreviations: Avoid using abbreviations unless they are widely recognized.

Practical case:

Suppose you want to write a function to check whether the input is valid, you can use the following function name:

• IsValidInput() (CamelCase nomenclature)
• IsValidInput (Pascal nomenclature)

Q3: How to deal with heavy What is the name of the loading function?

• Distinguish parameters: Use different parameter lists to distinguish overloaded functions, such as Add(int, int) and Add (double, double).
• Use suffixes: You can add suffixes to overloaded functions to distinguish them, such as Add_Int() and Add_Double().
• Namespace: Put overloaded functions into different namespaces, such as std::Add(int, int) and mylib:: Add(double, double).

Q4: What function naming conventions should be avoided?

• Single-letter names: such as i, j, lack of descriptiveness.
• Ambiguous: Such as DoSomething(), the meaning is unclear.
• Too specific: For example, GetCustomerByEmailAddress(), a more general name should be used (such as GetCustomer()).
• Use special characters: such as @, $, which are difficult to read.
