Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit I was wondering if anyone could help me. I have the following lines of code: for (i = 0; i <= NUMBINS; ++i) { printf("--------read in input files---------\n"); printf("The value if i is %d\n", i); fscanf(ifp1, "%f\n", &radius_microns); fscanf(ifp2, "%f\n", &volfraction); printf("The value of radius is %f\n", radius_microns); rad_array[i]= radius_microns; printf("The radius is rad_array[%d]=%f\n\n",i, rad_array[i]); printf("The value of volfraction is %f\n", volfraction); vol_array[i] = volfraction; printf("The volfraction is vol_array[%d]=%f\n", i, vol_array[i]); printf("The value of rad_array[%i] is %f\n", i, rad_array[i]); printf("----------end of read in input file------\n\n"); } which, in cygwin produces: --------read in input files--------- The value of i is 0 The value of radius is 0.200000 The radius is rad_array[0] = 0.200000 The value of volfraction is 0.330000 The volfraction is vol_array[0]=0.330000 The value of rad_array[0] is 0.330000 ----------end of read in input file----- as you can see, for some reason rad_array[0] is being reassigned even though I never ask for that!!! my red-hat linux gcc produces: --------read in input files--------- The value of i is 0 The value of radius is 0.200000 The radius is rad_array[0] = 0.200000 The value of volfraction is 0.330000 The volfraction is vol_array[0]=0.330000 The value of rad_array[0] is 0.200000 ----------end of read in input file----- which is the right answer. I cannot figure out what is going on with cygwin, and I haven't found a post that can help me. Any help is appreciated.
