The C programming language provides many standard library functions for file input and output.These functions make up the bulk of the C standard library header <stdio.h>. [1] The functionality descends from a "portable I/O package" written by Mike Lesk at Bell Labs in the early 1970s, [2] and officially became part of the Unix operating system in Version 7.

The C++ Standard Library is based upon conventions introduced by the Standard Template Library (STL), and has been influenced by research in generic programming and developers of the STL such as Alexander Stepanov and Meng Lee. [4] [5] Although the C++ Standard Library and the STL share many features, neither is a strict superset of the other.
In computer programming, run-time type information or run-time type identification (RTTI) [1] is a feature of some programming languages (such as C++, [2] Object Pascal, and Ada [3]) that exposes information about an object's data type at runtime. Run-time type information may be available for all types or only to types that explicitly have it ...
Object pools can be implemented in an automated fashion in languages like C++ via smart pointers. In the constructor of the smart pointer, an object can be requested from the pool, and in the destructor of the smart pointer, the object can be released back to the pool.
In C files do not exist as a built-in type (they are defined in a system header) and all I/O takes place via library calls. Pascal has file handling built into the language. The typical statements used to perform I/O in each language are:

Prior to C++20, C++ used a header file source code inclusion system to share declarations between source files. Since C++20, however, modules were introduced offering similar functionality to Java packages, however C++ modules do not have the same granularity of Java packages which allowing for importing individual functions or classes - rather ...
