Should You Use Custom Wrappers for `cout`, `cerr`, `cin`, and `endl` in C ?

C Standard Library: A Critique of Custom Wrappers for cout, cerr, cin, and endl

In an attempt to streamline coding, some developers explore methods to abbreviate the constant typing of std:: before standard input/output streams (i.e., cout, cerr, cin, endl). Custom wrappers, like those presented in the STLWrapper example, provide one solution. However, this approach raises questions about potential drawbacks and alternative approaches.

Potential Pitfalls of Custom Wrappers

While syntax issues have been addressed, other concerns remain:

• Overloading Hazards: Custom names for these objects conflict with potential user-defined functions. This can lead to unintended function calls.
• Objectively Clear Code: Prefixes such as std:: objectively improve code clarity. They eliminate ambiguity in identifier references, making it easier for both humans and compilers to discern the intended target.

Alternative Approaches

Instead of custom wrappers, a more effective method is to embrace the std:: prefix for improved code readability:

• Negligible Typing Cost: The time invested in typing std:: is minimal compared to the overall development process.
• Enhanced Readability: The prefixes add valuable clarity to each line of code, making it easier to comprehend and interpret.
• Developer Consensus: Developers who have adopted this approach report increased code readability and reduced reliance on using directives, solidifying its effectiveness.

Conclusion

While custom wrappers may offer a perceived convenience, they introduce potential drawbacks and compromise code readability. Embracing the std:: prefix provides an objectively clearer approach that enhances code maintenance and comprehension.
