You're pulling those numbers out of your ass.
You know that most C++ constructs don't come with any extra runtime cost, right? And that those that does are clearly documented, and usually you need to do something that cost as much to do the same in C (like using function pointers to emulate virtual methods)

Alternative: learn to code
Every feature of every language can be put to bad use. A programmer that sucks will manage to write shitty code no matter how many language features you forbid him to use.
Most, if not all the shitty C++ code I've seen seldom used any C++ feature that doesn't exist in java.
