Re: [ROOT] Iitialization of string characters

I did it under Windows and it works. However the original message
did not say what was wrong really.


By the way, it is better to let the compiler to define the array size as follows:

  char* HisXTit[] = {  }
  const int MaxHistos = sizeof(HisXTit)/sizeof(char *);

namely:

{
  gROOT->Reset();


  // Initialize array of pointers
  char* HisXTit[] = {
    "xCal",  "yCal", "yCal",
    "xHES",  "yHES", "yHES",
    "xCal",  "yCal", "yCal",
    "rCal",  "rCal", "rCal",
    "rHES",  "rHES", "rHES",
    "rCal",  "rCal", "rCal",
    "zCal",  "xCal", "xCal",
    "yCal",  "yCal", "zCal"
  };

  int i;

  const int MaxHistos = sizeof(HisXTit)/sizeof(char *);
  printf(" size = %d\n",MaxHistos);
  for(i=0;i<MaxHistos;i++){
    printf("%s\n",HisXTit[i]);
  }
}
