代码段如下.错误在cout行的foo函数中:

typedef struct Datatype {
    int first;
    int second;
} Datatype;

void foo(std::array<Datatype, 100>* integerarray){
    cout << *integerarray[0].first << endl; //ERROR: has no member first
}

void main() {
    std::array<Datatype, 100> newarray;
    for(int i=0; i<100; i++)
        newarray[i] = i;
    }
    foo(&newarray);
}
