测试点 #5 WA，请问是不能用两个数组吗

#include<iostream>
using namespace std;
int main()
{
    int book[10];
    double t = 0,a[10] = {28.9,32.7,45.6,78,35,86.2,27.8,43,56,65};
    for(int i = 0;i < 10;i++)
        cin >>book[i];
    for(int i = 0;i < 10;i++)
        t+=book[i] * a[i];
    cout << t << endl;
    return 0;
}

麻烦各位帮忙看一下，谢谢！
