Array of char pointers.
If I had to say what "arr" is, I would say it is an array of pointers to chars. If so why is it intialized with strings instead of addresses? char *arr[] = { "a", "b", "c","dd", "eee" }; Also when looking at the values of the pointers (when they appear to be adjacent) they seem to decrease by at leas... 21 Apr 2008 12:29

which design is better to wrap another class instance
Hello everyone, Some people doubt that the design below is inferior compared to design which makes f, either Foo* or Foo&. The reason is below design will waste memory space and degrade performance by creating a new instance. I think it depends.
