Quite a newbie question as is.
Functions in a C library can be used and accessed by programmers to create several different programs. As a programmer, you may find yourself using the same function or functions repeatedly. In this case, it is best to put this function or functions in a library to speed up the compilation of the program.
The ANSI C standard library consists of 24 C header files which can be included into a programmer's project with a single directive. Each header file contains one or more function declarations, data type definitions and macros.
Oracle Developer Studio C and C++ compilers use compatible headers, and use the same C runtime library. They are fully compatible.
If you disassemble the program, you can see only your code is there, there is no standard library bloat in it. So you can use C without the standard library.
Yes. There is no reason you cannot use C libraries in C++. Things change if you want to compile C in a C++ compiler. The C ABI is fully supported from C++, however things are not necessarily so neat from an API perspective. Certain C additions such as restrict
are not in the C++ standard, and must be dealt with carefully.
If the headers are properly protected with extern "C" { ... }
, then yes.
