RE: [Dev-C++] MINGW GCC 3.x II

 Hi,

Can anybody explain me why the following Code works:

void ReadData(const char* s)
{
  extern Prozessfaehigkeit pf;
  
  ifstream in(s);
  string line;

  getline(in, line);
  pf.MeanS = (atof(line.c_str()));
[...]

and 

void ReadData(const char* s)
{
  extern Prozessfaehigkeit pf;
  
  ifstream in(s);
  string line;

  getline(in, line);
  pf.MeanS = atof(line.c_str());
[...]

works not ? Why is there a need for brackets ?
Thanks in advance,
Greetings 
Horst
