Cannot write .csv file to StringGrid in C++ Builder -

edit: codeblock edited, problem last line of .csv file printed in each row of stringgrid. can reason? in advance.

basically , 1 module of project create output file toushands of point coordinates in comma seperated format shown below :

#pt,     x     ,     y     ,z     124,4500003.833,3499999.500,0 125,4500003.833,3499999.833,0 126,4500003.833,3500000.167,0 

what i'm trying reading .csv module , put stringgrid.

 file *coord;   //some other things here  while (fgets(line,100,dosyagiris)!=null) {   sscanf(line,"%d,%lf,%lf,%lf",&number,&x,&y,&z);         (col = 0; col < 4; col++) {                  stringgrid1->cells[0][row] = inttostr(number);                 stringgrid1->cells[1][row] = floattostr(x);                 stringgrid1->cells[2][row] = floattostr(y);                 stringgrid1->cells[3][row] = floattostr(z);          }  } 

please constructive , have one.

it not working because of unnecessary loop, works.

        int i= 0;         while (fgets(line,100,dosyagiris)!=null){             sscanf(line,"%d,%lf,%lf,%lf",&id,&x,&y,&z);                  stringgrid1->cells[0][i+1] = inttostr(id);                 stringgrid1->cells[1][i+1] = floattostr(x);                 stringgrid1->cells[2][i+1] = floattostr(y);                 stringgrid1->cells[3][i+1] = floattostr(z);                 i++;          }
