c++ - Output always 65535 characters? -


this code.

#include <iostream> using namespace std;  int main()  {     string s;     cin >> s;     cout << s.length();     return 0; }

note limitation has nothing c++ language, or particular implementation of it. limitation ideone (and it's understandable. wouldn't want allow people upload unlimited data fill server). appears behaviour silently truncate input.
