Следует ли использовать try-кроме с self.fail

#include <iostream>
#include <string>

using namespace std;

int validatedInput(int min = 1, int max = 3)
{
    while(true)
    {
        cout << "Enter a number: ";
        string s;
        getline(cin,s);
        char *endp = 0;
        int ret = strtol(s.c_str(),&endp,10);
        if(endp!=s.c_str() && !*endp && ret >= min && ret <= max)
            return ret;
        cout << "Invalid input. Allowed range: " << min << "-" << max <<endl;
    }
}

int main(int argc, char *argv[])
{
    int val = validatedInput();
    cout << "You entered " << val <<endl;
    return 0;
}
