] | What's the C++ way of parsing a string (given as char \*) into an int? Robust and clear error handling is a plus (instead of [returning zero](http://en.cppreference.com/w/cpp/string/byte/atoi)). | In the new C++11 there are functions for that: stoi, stol, stoll, stoul and so on.
```
int myNr = std::stoi(myString);
```
It will throw an exception on conversion error.
Even these new functions still have the **same issue** as noted by Dan: they will happily convert the string "11x" to integer "11".
