從鍵盤中給整型數組a[20]輸入20個正整數，求出a 中奇數的個數和奇數的平均值

#include <stdio.h>

void main(void)

{

int a[20];

int i = 0;

for( ;i < 20;i++ )

{

scanf("%d",&a[i]);

}

int num = 0;

int sum = 0;

for(i=0;i<20;i++)

{

if(a[i]%2 == 1)

{

num++;

sum+=a[i];

}

}

printf("The number of odd number is:%d\n",num);

printf("The odd numbers's average value is:%.2f\n",sum*1.0/num);

}
