Jun 15, 2018 · To write a C++ object in XCode, just do it. Create .cpp and .h files like you would anywhere else. When you need to interact with a C++ object from Objective-C, you can either go into the properties of the .m file in XCode and change it to use the Objective-C++ compiler, or (better yet) just name it .mm instead of .m.
Jun 24, 2021 · In C++ there are number of stream classes for defining various streams related with files and for doing input-output operations. All these classes are defined in the file iostream.h. Figure given below shows the hierarchy of these classes. ios class is topmost class in the stream classes hierarchy. It is the base class for istream, ostream, and ...
Jan 4, 2018 · ios::app (short for append) means that instead of overwriting the file from the beginning, all output operations are done at the end of the file. This is only meaningful if the file is also open for output. ios::trunc (short for truncate) means that when the file is opened, the old contents are immediately removed.

The insertion operator (<<) is used to put information into an output stream. C++ has predefined insertion operations for all of the built-in data types, and you’ve already ...
