Hi out there,

I am sorry if this is faq for this newsgroup.   Here is my question:

How can I simulate "pointer to char" by an array in a class whose size will be delayed to be
defined at run time?

For example,


          class X {

          private:
                   char string[      ];    /* not define size of the array */
                              ^^^^^^^^       
          public:
                   X(int);

                   ...............
          };


          X::X(int size) {
                 string[size];          /*  define size of string array now  */
                 strcpy(string, "Hello");
          }

Any pointer to this problem will be greatly appreciated.   Thanks in advance.
