 | Here's another way to use a vector of function pointers. This uses c-style function pointers, and this could probably be simplified too.

| | line 16: variable [b]a[/b] is NOT a string but just an array of characters because it is not null terminated. So string functions such as [b]strlen()[/b] (line 18) and [b]cout[/b] (line 29)will not work with it. To use strlen() you should have declared it like this: [icode]char a[] = "tanka";[/icode] … |
