背景： 刪除 bmp格式檔案 （建立日期超過當天的時間）

示例程式碼如下：

#include<iostream>
#include<io.h>
#include<time.h>
#include<string>
#include<Windows.h>

int main()
{
    while(1)
    {
        char* fileName = "./*.bmp";
        struct _finddata_t fileInfo;
        long handle;
        handle = _findfirst(fileName, &fileInfo);
        
        if(-1 == hanlde)
        {
            cout<<"*.bmp file is not exist!\n";
        }
        else
        {
            cout<<fileInfo.name<<endl;
            
            char curTimeStr[64] = {0};
            time_t timeCur;
            time(&timeCur);
            strftime(curTimeStr, sizeof(curTimeStr), "%Y-%m-%d", localtime(&timeCur));
            string curTime(curTimeStr);

            char timeStr[64] = {0};
            time_t timep = fileInfo.time_create;

            strftime(timeStr, sizeof(timeStr), "%Y-%m-%d", localtime(&timep));
            string tTime(timeStr);

            if(tTime < curTime)
            {
                if(remove(fileInfo.name) == 0)
                {
                    cout<<"del file success!\n";
                }
                else
                {
                    cout<<"del file fail, errorcode = "<<GetLastError()<<endl;
                }
            }
            while(!_findnext(handle, &fileInfo))
            {
                cout<<fileInfo.name<<endl;
                
                time_t timep = fileInfo.time_create;

                memset(timep, 0, 64);
                strftime(timeStr, sizeof(timeStr), "%Y-%m-%d", localtime(&timep));
                string tTime(timeStr);
                if(tTime < curTime)
                {
                    if(remove(fileInfo.name) == 0)
                    {
                        cout<<"del file success!\n";
                    }
                    else
                    {
                        cout<<"del file fail, errorcode = "<<GetLastError()<<endl;
                    }
                }
            }
        }
        _findclose(handle);
        Sleep(3600000);
    }
    return 0;
