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’.

intia[]= {0,1,2}; vector<int>ivec(ia, ia+sizeof(ia)/sizeof(int)); 只是個便宜行事的寫法,因為vector本身並沒有如boost::array提供initializer,所以借用了array的initializer,再由array轉vector。實務上是用pushback()將資料塞進vector。 重點應該放在14行 voidfunc(vector<int>const&ivec) { 只需傳...

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. ...

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...
