C++ builder How to read float numbers from text file and put into 2d dynamic array

Here is my code

include "string"

include "fstream"

if(!Opendialog1->Execute()) return; String Name = Opendialog1-> FileName;

std::ifstream is(Name.c_str()); if(!is.is_open()) return; std::string s;

while (!is.eof()) { std::getline(is.s); String S=s.c_str(); }

int colcount = StrToInt(Edit1->Text); int rowcount = StrToInt(Edit2->Text); float *array = new float [rowcount] for ( int i =0 ; i<colcount+1; i++) { array[i] = new float [colcount]; }

My .txt file is 0,15 0,3 0,5 0,8 0,9 0,76 0,32 0,45 0,74 0,99 0,34 0,21 0,34 0,45 0,73 0,11 0 0,13 0,89 0,19
