ماهو الفرق بين c و ++c وماذا اختار ؟

أرجوك لا تكرر السؤال حتي لا تقيم سلبا و يعتبروك سبام

و هذا جواب على سؤالك و لكنه باللأنجليزية

You pick C when

you need portable assembler (which is what C is, really) for whatever reason,
your platform doesn't provide C++ (a C compiler is much easier to implement),
you need to interact with other languages that can only interact with C (usually the lowest common denominator on any platform) and your code consists of     little more than the interface, not making it worth to lay a C interface over C++ code,
you hack in an Open Source project (many of which, for various reasons, stick to C),
you don't know C++.
In all other cases you should pick C++.
