Objective-C++ may sound like a new programming language, but it’s not. It’s a combination of two languages, Objective-C and C++. Apple provides Objective-C++ as a convenient mechanism for mixing Objective-C code with C++ code. Objective-C is close to C but with object-oriented features implemented as a thin layer on top of C. It’s a strict superset...
Objective-C++ doesn’t actually merge Objective-C with C++ features. Meaning, Objective-C classes won’t have features that are available to C++ and vice versa. The following code examples illustrate these limitations:
The ability to reuse existing C/C++ libraries is one of the most important use cases in considering native languages and it’s a straightforward process in iOS. While Android still requires a separate NDK, iOS already supports C and C++.
As you have seen, C and C++ development in iOS is straightforward through the use of Objective-C++. If you’ve been programming with C or C++ before then it’s easier now to transition to iOS development and leverage your existing skills. Best of all, you can take advantage of existing C/C++ libraries like the powerful SDL with minimal configuration....

Jan 4, 2018 · AFAIK The difference between ios::out and ios::trunc is when reading (and writing) from the file, i.e. when using fstream, not ofstream. @Barmer's answer is correct for fstream, but the question is about ofstream, so he is wrong here. This is the correct answer. – zzz. Dec 7, 2023 at 22:21.
Sep 11, 2023 · 28.1 — Input and output (I/O) streams. Input and output functionality is not defined as part of the core C++ language, but rather is provided through the C++ standard library (and thus resides in the std namespace). In previous lessons, you included the iostream library header and made use of the cin and cout objects to do simple I/O.
