如何遍历字符串数组，将每个字符串与c++中的字符字符串进行比较。

#include <iostream>
#include <string>

int main() {
    std::string arr[] = {"apple", "banana", "cherry"};
    std::string target = "apple";

    int size = sizeof(arr) / sizeof(arr[0]); // 计算数组长度

    for (int i = 0; i < size; i++) {
        if (arr[i] == target) {
            std::cout << "String found at index " << i << std::endl;
            break;
        }
    }

    return 0;
}
