How to parse a string to an int in C++?
... problem: what if the caller needs to distinguish 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 h...

The key point is mentioned in the answer ab...
