如何遍历std::vector<std::string>

遍历std::vector<std::string>的方法有很多种，这里给出两种常见的方法：

方法一：使用下标遍历

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

int main() {
    std::vector<std::string> vec = {"hello", "world", "example"};
    for (size_t i = 0; i < vec.size(); ++i) {
        std::cout << vec[i] << std::endl;
    }
    return 0;
}

方法二：使用迭代器遍历

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

int main() {
    std::vector<std::string> vec = {"hello", "world", "example"};
    for (std::vector<std::string>::iterator it = vec.begin(); it != vec.end(); ++it) {
        std::cout << *it << std::endl;
    }
    return 0;
}
