STL string没有能查多个字符串的函数，但可以查多个字符。

代码

#include <algorithm>
#include <iostream>
#include <string>
using namespace std;
const string a[] = {"Apple", "iPhone", "iPod", "iPad", "Sony"};
string str;
inline void cal(int pos) {
    for (int i = 0; i < 5; ++i) {
        if (str.substr(pos, a[i].size()) == a[i]) {
            if (i == 4)
                cout << "SONY DAFA IS GOOD!
";
            else
                cout << "MAI MAI MAI!
";
            return;
        }
    }
}
int main() {
    ios::sync_with_stdio(false);
    cin.tie(NULL);
    while (getline(cin, str)) {
        int pos = 0;
        while ((pos = str.find_first_of("AiS", pos)) != string::npos) {
            cal(pos);
            ++pos;
        }
    }
    return 0;
}
