Array of function pointers

What I need to do is have a array of pointers in a class without knowing how many items I need in the array. How do I deal with that ? Can I declare a pointer in the declaration and then define it as an array in the constructor for example ?

That depends on when you know how may pointer you need. If you know it at constructor time, you can create a pointer to an array of pointers and allocate the memory at constructor time for just the number of elements you need.

void (**pfa)(char*);

void xyz(char *x)
{}

X:x(int n) {
  pfa = new (void (*[n])(char *));
  pfa[0] = xyz;
}

pfa[0]("hello");

If you want real dynamic array, you need to use the vector class from the Standard Library.
