关于数组和指针的测试

char *p1 =  "hello" ;      char *p2 =  "world" ;      char *p3 =  "a piece of cake" ;      char *str[] = { p1, p2, p3 };      cout <<  sizeof (*str[0]) <<  " " <<  typeid (str[0]).name() <<  " " << *(str[0] + 1) << endl; //typeid是类型      cout <<  sizeof (*&str[0]) <<  " " <<  typeid (&str[0]).name() <<  " " << *(&str[0] + 1) << endl;      cout <<  sizeof (*str) <<  " " <<  typeid (str).name() <<  " " << *(str + 1) << endl;      cout <<  sizeof (*&str) <<  " " <<  typeid (&str).name() <<  " " << *(&str + 1) << endl;      return 0;
