⼤致如下：

typedef struct
{
long long int  molecular;

int change_to_proper_fraction(FRACTION *fraction);
void fraction_add(FRACTION *frac_sum, FRACTION *frac_num);

long long int diff = 0;

printf怎么输出字符mole_posi = fraction->molecular > 0 ? fraction->molecular : (0 - fraction->molecular);
deno_posi = fraction->denominator > 0 ? fraction->denominator : (0 - fraction->denominator);
smaller = mole_posi
diff = deno_posi + mole_posi - 2 * smaller;
larger = diff>smaller ? diff : smaller;
smaller = diff + smaller - larger;
while (larger%smaller != 0)
{
diff = larger - smaller;
larger = diff>smaller ? diff : smaller;
smaller = diff + smaller - larger;
}
fraction->molecular = fraction->molecular/smaller;
fraction->denominator  = fraction->denominator/smaller;
return 0;
}
void fraction_add(FRACTION *frac_sum, FRACTION *frac_num)
{
if (frac_sum->molecular == 0)
{
frac_sum->molecular = frac_num->molecular;
frac_sum->denominator  = frac_num->denominator;
return;
}
else if (frac_num->molecular == 0)
{
return;
}
else
{
frac_sum->molecular = frac_sum->molecular*frac_num->denominator + frac_num->molecular*frac_s
um->denominator; frac_sum->denominator = frac_sum->denominator * frac_num->denominator;
change_to_proper_fraction(frac_sum);
return;
}
