求奇数的乘积：

#include<iostream>
using namespace std;
#define N 1000
int a[N];
int main(){
    int n;
    while(cin>>n){
        int i;
        long long sum=1;
        for(i=0;i<n;++i){
            cin>>a[i];
            if(a[i]%2!=0)
                sum*=a[i];
        }
        cout<<sum<<endl;
    }
    return 0;
}
