#include <iostream> using namesapce std;
 void test(int t) {   if(t > 10)     throw "integer larger than 10!";   else     cout << "t = " << t << endl; }
 int main() {   try {     test(21);   } catch(char *str) {     cout << str << endl;   } catch(...) {     cout << "unexpected error\n";   } }

这个的结果是
  unexpected error.
除非， catch(const char*str) {....}
 才会是 integer larger than 10!
