c++写日记簿程序

好的，下面是一个简单的C++日记簿程序实现：

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

using namespace std;

int main()
{
    string filename = "diary.txt";
    string content;
    time_t now = time(0);
    tm* ltm = localtime(&now);
    int year = ltm->tm_year + 1900;
    int month = ltm->tm_mon + 1;
    int day = ltm->tm_mday;
    int hour = ltm->tm_hour;
    int minute = ltm->tm_min;
    int second = ltm->tm_sec;

    cout << "请输入日记内容：" << endl;
    getline(cin, content);

    ofstream outfile;
    outfile.open(filename, ios::app);
    outfile << year << "-" << month << "-" << day << " " << hour << ":" << minute << ":" << second << endl;
    outfile << content << endl;
    outfile << "----------------------------------------" << endl;
    outfile.close();

    cout << "日记已保存成功！" << endl;

    return 0;
}

这个程序会提示用户输入日记内容，然后获取当前时间，最后将时间和内容写入到文件“diary.txt”中。
