A string is a class that contains a char array, but automatically manages it for you. Most string implementations have a built-in array of 16 characters (so short strings don't fragment the heap) and use the heap for longer strings. You can access a string's char array like this: std...
An array of char is not really different from an array of int or any other array of numeric type; it's just that the language offers some extra ways to write objects of type char and arrays of them, and there is a general convention (systematized with functions like strlen) for how ...
An std::string is a class that is much like a vector. Internally, it handles the storage of an array of characters, and gives the user several member functions to manipulate said stored array as well as several overloaded operators. Reasons to use a char* over an std::string: C backward...

Thus, array (pointer (char), 4) is the type of arrays of 4 Pointers to char. 因此y的类型就是有四个元素、这些元素指向char类型的指针数组。 For most char drivers, there is little benefit to be gained from AIO support. 对于大多数字符设备驱动,支持AIO并不能获得太多好处。 The second diff...
