I.e. in this case, x = 0 if the string has any non-integer characters, or x = value of string-as-integer otherwise. So the neat thing is this is one short expression which...
How to extract the first two characters of a string in shell scripting?

...oo {
public:
// Overloaded call operator
int operator()(const std::string& y) {

}
};
Usage:
