指向数组的指针(Pointer to an array).doc,指向数组的指针(Pointer to an array) If I have a definition int (* p) [3]; A pointer variable called p is defined, indicating that p is a pointer variable, which can point to a two-dimensional array of three int
the pointer ‘ptr’ contained the address of ‘ch’ and in the next line it contained the address of ‘c’. In other words, we can say that Initially ‘ptr’ pointed to ‘ch’ and then it pointed to ‘c’.
If you do need to have a pointer to"c"(in the above example), it will be a "pointer to a pointer to a pointer" and may be declared as − int***d=&c; Mostly, double pointers are used to refer to a two−dimensional array or an array of strings. ...

Here, is an example of an array and a pointer being used to identify a particular element. One of the most powerful features of using pointers with arrays is that incrementing a pointer always moves it to the next element in the array, regardless of the number of bytes that each element...

That's because you weren't printing an std::string. You were printing an array of std::strings. Trystd::cout <<myStringinstead. (also i did add in passing the length, thats why it started showing the entire array) Oh. In that case, to answer your previous question: imagine you have...
