Structures in C and C++ differ in that C structures do not have an automatic typdef associated with them.
It doesn't. Void has the same meaning in both.
Yes, but overloads cannot differ by return type alone. The signatures must differ by the number and/or the type of the arguments.
The first in a company developping a well-known database system, the second is a programming language.
Turbo C++ keywords are the same as C++ keywords. The language remains the same, only the implementations differ. The Turbo C++ implementations were standards-compliant at the time of their release, but the product is no longer supported.
They differ insofar as C does not use object-oriented programming at all -- there are no classes (only structures), therefore there was nothing to abstract. C++ (which literally means 'the successor to C') is an extension of C that primarily adds object-orientated support to the language. Everything you can do in C you can also do in C++, but with the added benefits of OOP you can do a whole lot more, more easily, including the creation of abstract data types.
