What you say is a little bit confusing. I assume that you want this:


#include <iostream>

class C {
public:
  static const int ciSize=10;
  static const char apszString[ciSize];
};

const int C::ciSize; // no initialization here ! 
const char C::apszString[ciSize]="123456789";

int main() {
  cout << c::apszString << endl;
  return 0;
}


This is Standard C++ and gcc 2.95 and 2.8.1 do compile it correctly.
