[GNHLUG] Silly C/C++ question...

[bruce.labitt at autoliv.com]

I am sure I will kick myself when I find out the answer, but...

I have a text file that for now consists of 3 lines, later it will have
  data.
  line 1: integer representing the array size
  line 2: four doubles separated by commas
  line 3: \n

Here is the code fragment that I have been trying to get to work.  I have
no idea why I am getting the output I am.

double fstart1, fend1, , M1, dt1 ;  int N;
FILE *fp;
fp = fopen("/home/workspace/input3.txt", "r"); // open input3 file for
reading
printf("input3.txt opened for reading.\n ");

fscanf(fp, "%i", &N);                                    // Find file
length ==> read first line
printf("file length is %i\n", N);                        // all is good

fscanf(fp, "%d%d%d%d", &fstart1, &fend1, &M1, &dt1);     // get fstart,
fend, number of doppler slices & dt
printf(" fstart = %d  fend = %d number of doppler slices = %d dt = %d \n",
fstart1, fend1, M1, dt1);

fclose(fp);

The output of the file is:
input3.txt opened for reading.
 file length is 1024
 fstart = -1706024  fend = -1705632 number of doppler slices = 1049224 dt =
 268505456

The values for input3.txt are:
line 1: 1024
line 2: -50e6, 50e6, 256, 5e-10
line 3: \n

Umm, what am I doing wrong?

Thanks,
Bruce
