The C + + programming Language Learning Note the 5th chapter pointers, arrays, and structures

1. The value of the pointer to the output pointing to the character.

Now defined, Char c= ' a ', char* pc=&c. In C, it only takes printf ("%p\n", PC) to output this value, whereas in C + +, if cout<<pc<<endl; a strange string of characters, what's going on? Because the i/class in the C + + standard library overloads the << operator, it is treated as a string name when the character pointer is encountered, outputting the string that the pointer refers to. So we can convert its first to void* and then output.  cout << static_cast<const void*>(pc) << endl。有点麻烦，不过平时一般也不会要求输出这个值，所以就记住就好啦。
