使用fstream C++编辑初始化的结构成员

#include <iostream>
#include <fstream>
#include <string>

struct Person {
    std::string name;
    int age;
};

void writeToFile(const Person& person, const std::string& filename) {
    std::ofstream outFile(filename);
    if (outFile.is_open()) {
        outFile << person.name << " " << person.age << std::endl;
        outFile.close();
    } else {
        std::cerr << "Unable to open file" << std::endl;
    }
}

bool readFromFile(Person& person, const std::string& filename) {
    std::ifstream inFile(filename);
    if (inFile.is_open()) {
        inFile >> person.name >> person.age;
        inFile.close();
        return true;
    } else {
        std::cerr << "Unable to open file" << std::endl;
        return false;
    }
}

std::ofstream outFile(filename);
if (!outFile) {
    // 文件打开失败，处理错误
    std::cerr << "Unable to open file: " << filename << std::endl;
    return;
}

// 写入文件
outFile << person.name << " " << person.age << std::endl;

// 读取文件
inFile >> person.name >> person.age;
