- There is no vector<...> type, we only use arrays
- There are no namespaces
- void main() is allowed by the compiler (in more recent compilers main() must return something, if I understand correctly)
- Standard libraries still have to be written with a ".h" at the end (e.g.: #include <iostream.h> instead of <iostream>)
Over time I got used with the (apparently) outdated version of the language I have to use at school, but I was wondering: how old exactly is the C++ we are being taught? When were the changes I listed above first implemented?
