How to identify a new line in C++?

Question

I have to take integer input to an integer array. I have to identify the newline also in input. To be more clear, I have an example. The input I am giving is:-

2         


        

Answer 1

though you mention c++ here is something that i often use to read in an array of doubles from a file

 char line[512+1];

  unsigned int row = 0 ;
  unsigned int col = 0 ;

  while( fgets(line, sizeof(line), file) )
    {
      col = 0 ;
      tempChr = strtok(line, delimters);

      // ignore blank lines and new lines
      if ( tempChr[0] == '\n' )
    {
      continue ;
    }

      tempDbl = atof(tempChr);

      data[row*numCols+col] = tempDbl ;


      for(col = 1 ; col < numCols ; ++col)
    {
      tempDbl = atof(strtok(NULL, delimters));
      data[row*numCols+col] = tempDbl;
    }

      row = row + 1;
      if( row == numRows )
    {
      break ;
    }
    }
