可以使用迭代器或范围 for 循环来遍历 std::vector

使用迭代器:

#include <iostream>
#include <vector>
#include <string>

int main() {
    std::vector<std::string> v = {"hello", "world", "how", "are", "you"};
    for (auto it = v.begin(); it != v.end(); ++it) {
        std::cout << *it << " ";
    }
    std::cout << std::endl;
    return 0;
}

使用范围 for 循环:

#include <iostream>
#include <vector>
#include <string>

int main() {
    std::vector<std::string> v = {"hello", "world", "how", "are", "you"};
    for (const auto& s : v) {
        std::cout << s << " ";
    }
    std::cout << std::endl;
    return 0;
}

两种方法都可以遍历 std::vector,但范围 for 循环更加简洁和易读
