你自己做啊
main()
{int i,j=0,k=0,r=0,s=0;
scanf("%d",&i);
if(i!=0)
{if(i%2==0)
j++,r+=i;
else k++,s+=i;}
printf("%d\n",r/j);
printf("%d\n",s/k);
}
#include
int main()
{

while(scanf("%d",&a))
{
if(a==0) return 0;
if(a%2==0) {sum1+=a;total1++};
else {sum2+=a;total2++;}
}

printf("奇数个数: %d, 奇数平均数: %f\n", sum2, float(sum2)/total2);
}
哦 是吗 我还不知道啊
#include
void main()
{
int count_odd, count_even; //计数
float sum_odd, sum_even; //求和
int number, i;
count_odd = count_even = i = 0;

0;
while (1)
{

scanf("%d", &number);
if (number == 0)
break;
if (number % 2 == 0)
{
count_even++;
sum_even += number;
}
else
{
count_odd++;
sum_odd += number;
}
}
if (count_odd == 0 && count_even == 0)
printf("Just 0 input。
\n");
else //保证被除数不为0
{
printf("\nThe number of odd numbers is: %d, and the average is: %5。2f\n", count_odd, count_odd==0 ? 0 : sum_odd/count_odd);
printf("The number of even numbers is: %d, and the average is: %5。
2f\n", count_even, count_even==0 ? 0 :sum_even/count_even);
}
}
。
