Why Is 'super' Not a Standardized Keyword in C ?

The Power of "super" in C

The concept of "super" in object-oriented programming allows derived classes to reference their base classes. While C lacks a dedicated "super" keyword, it provides an alternative solution using typedefs. This article explores the use of "super" through typedefs, addressing its prevalence, validity, and potential standardization.

Common Use of "super"

While the usage of "typedef super" may vary, it is generally uncommon in codebases. However, it offers convenience when working with verbose or templated base classes. Its simplicity and expressiveness make it a compelling choice for certain scenarios.

Validity of Using "super"

The use of "typedef super" is technically valid and effective. It allows derived classes to alias their base classes, enabling concise constructor initializations and method overrides. Furthermore, it supports chaining of base class references.

Standardization of "super"

The concept of "super" has been proposed for standardization in C in the past, but the proposal was ultimately rejected due to its low perceived value. However, the typedef approach remains a viable solution that addresses many of the same needs.

Private or Public "super"

It is generally recommended to keep the "super" typedef private. This prevents derived classes from accessing the superclass directly, promoting encapsulation and preventing potential misuse. Private "super" also enables chained base class references, though this feature is rarely utilized.

Conclusion

The use of "super" through typedefs in C is a legitimate technique that offers certain advantages. While it may not be standardized in C , it provides an effective workaround and enhances code readability in specific situations. Whether or not to use "super" depends on individual coding styles and project requirements.
