Bad practice to use fopen and then neglect to verify that the file was
actually opened. If the call to fopen fails, then fp will be NULL and
your subsequent call to fprintf will fail. You should do
FILE *fp;
if((fp = fopen("xdKm.txt", "a+") == NULL) {
/* handle error, print msg, exit function, etc */
}
fprintf(...);
close fp;
I also question the way you are using fprintf -- why use a format
string if you are using a string const? Why not just do
fprintf(fp, "I am Here2\n");
or even
fputs(fp, "I am Here2\n");
