How to parse a string to an int in C++?
...tinguish between bad input (e.g. "123foo") and a number that is out of the range of int (e.g. "4000000000" for 32-bit int)? With stringstream, there is no way to make this distinction. We only know whether the conversion succeeded or failed. If it fails, we have no way of knowing why it failed. As y...
What's the best way to refactor a method that has too many (6+) parameters?
...e minSpeed and maxSpeed parameters and put them in a new type:

}
bool SpeedIsAcceptable(SpeedRange sr, int currentSpeed)

return currentSpeed >= sr.Min & currentSpeed < sr.Max;
}
This is better, but to really take advantage ...
