c++ - Validate string within short range -

i have short integer in string. eg: "123456". there api check whether string contains valid number in range of unsigned short?

thanks!

simply use stream operators input number:

istringstream istr("12346"); short s; if ((istr >> s) , istr.eof())     cout << "valid: " << s << endl; else     cout << "invalid" << endl; 

(needs header sstream.)
