note scanf() can be tricky. It might be better to use fgets()
followed by atoi() or (better) strtol(). Read the documentation for
them.

Oh, and try and get a copy of K&R

The fscanf equivalent of fgets is so simple
that it can be used inline whenever needed:-
char s[NN + 1] = "", c;
int rc = fscanf(fp, "%NN[^\n]%1[\n]", s, &c);
if (rc == 1) fscanf("%*[^\n]%*c);
if (rc == 0) getc(fp);
