Computer programming.
Yes.
It's primary purpose is to develop programs for the Windows platform.
Object oriented programming. General purpose. Cross-platform.
The header, io.h, is part of the standard C library and contains declarations for file handling and I/O functions. The file has no practical purpose in C++; it is only included because it was required prior to C++ standardisation. However, it can be used when writing C-style programs and libraries in C++.
b+b+b+c+c+c+c =3b+4c
c + c + 2c + c + c = 6c
Informatics is, broadly speaking, the science of information (amongst other things). C++ is, specifically, a cross-platform, general purpose, programming language.
b + b + b + c + c + c + c = 3b + 4c
Prolog is a high-level general purpose logic programming language, typically used in artificial intelligence applications. C++ is an intermediate-level general purpose programming language, suitable for a broad range of applications.
4c
No. .NET programming is Microsoft-specific, similar to Java in some respects, but it is non-portable. C++ is a general purpose and cross-platform programming language.
c + c + c + c + c = 5 * c.
