You would have to use coding.
yes! why not! this c program is used in ATM servicesand also in games.
Yes, you can program games with C++.
You can create an exe-file from your C++ source, if you have a compiler.
Use function mkdir.
It is used to distinguish between the C or C++
A simulator is a computer program which reproduces the behaviour of one system upon another system. Computer languages are used to create computer programs.
They are both used to create general purpose, native machine code programs. C++ evolved from C and essentially adds object-oriented programming to the language, making it easier to produce highly-complex, highly-robust and highly-scalable solutions that would be difficult to produce with C alone.
class class_name { private: data_members; public: member_functions; };
Of course they are used. Both stand-alone and class-member functions are used in C++.
Programming.
C++, but it's always worth learning both, if only to better understand the machine code you create with C++.
