Only if not able to do import std, or pre-compiled headers, and not using modern IDEs with "just my code" filters.

As someone that enjoys C++ since 1993, alongside other ecosystems, many pain points on using C++ complaints are self inflicted, by avoiding using modern tools.

Heck, C++ had nice .NET and Java alike frameworks, with bounds checking even, before those two systems came to exist, and nowadays all those frameworks are mostly gone with exception of Qt and C++ Builder ones, due to bias.
