杭电oj 求奇数的乘积

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int i,n,a;
    int sum = 1;
    while(scanf("%d",&n)!=EOF)
    {
        for(i=0;i<n;i++)
            {scanf("%d",&a);
                if(a%2!=0)
                    {sum = sum*a;}
            }
            printf("%d\n",sum);
            sum = 1;
    }
    return 0;
