There is no such keyword or data type known as tbuffer in C++. It's most likely an user-defined identifier, possibly a text buffer. But without knowing its actual type or its context it's impossible to say what it means.
If you mean the original name of C++, it was originally called "C with Classes". However, after the introduction of template metaprogramming, it was renamed C++ which meant "the successor to C".
I'm not exactly sure what you mean by this, but if you'd like to know how to do this in C here: q ^ 2 + 20 q + c
Just eat a watermellon!
C is not an object-oriented programming language and therefore has no objects as such. However, the term is often used in a more general sense to mean any instance of an user-defined or primitive variable/constant. In C++, the term is used specifically to mean any instance of a class.
C: there are no methods in C. C++: no.
It is used to distinguish between the C or C++
I guess you mean Java, there is no interface in C++.
c is any constant value
b=2 a=1 c=3 so b plus a =c

Objects that are not supposed to be written. Surprised?
b+b+b+c+c+c+c =3b+4c
c + c + 2c + c + c = 6c
b + b + b + c + c + c + c = 3b + 4c
4c

the answer is that a plus c is equal to b.
