C++常用小工具……

1. 批量改变文件内容：

//批量改变输出文件内容
#include <fstream>
#include <iostream>
#include <string>

using namespace std;

int main(){
    ifstream input("D:pos_img.txt");
    ofstream output("D:pos_image_o.txt");
    string strin,strout;
    while(input>>strin){
        strout ="pos_image/"+strin;
        strout+=" 1 0 0 40 40";
        output<<strout<<endl;
    }
    return 0;
}

效果如图：

      改前                                    改后

2 .利用TinyXML把.xml转化为.txt,以便日后离线处理。

#include "tinystr.h"
#include "tinyxml.h"
#include "concrt.h"
#include <fstream>

#include <iostream>
#include <string>

using namespace std;

ofstream output("D:ImageInfo.txt");

bool ReadXmlFile(string& szFileName){
    TiXmlDocument *myDocument = new TiXmlDocument(szFileName.c_str());
    if(!myDocument->LoadFile())
        return false;

    TiXmlElement *RootElement = myDocument->RootElement();
    TiXmlElement *ItemsElement = RootElement->FirstChildElement()->NextSiblingElement();

    TiXmlElement *ItemElement = ItemsElement->FirstChildElement();
    for(;ItemElement!=NULL;ItemElement=ItemElement->NextSiblingElement())
    {//Item循环
        TiXmlAttribute *ItemAttribute = ItemElement->FirstAttribute();
        output<<ItemAttribute->Value()<<endl;

        TiXmlElement *LabelElement = ItemElement->FirstChildElement();
        for(;LabelElement!=NULL;LabelElement=LabelElement->NextSiblingElement())
        {//子元素Label循环
            TiXmlAttribute *labelAttribute = LabelElement->FirstAttribute()->Next();
            for(;labelAttribute!=NULL;labelAttribute=labelAttribute->Next())// Label属性循环
                output<<labelAttribute->Value()<<endl;
            //Concurrency::wait(1000);//输出到控制台的时间控制
        }
        output<<endl;
    }
    cout<<"complete";
    return 1;
}

int main(){
    string fileName = "D:dongnanmeneast_15_1920x1080_30_R1.xml";
    //CreateXmlFile(fileName);
    ReadXmlFile(fileName);
}

TinyXML源文件+main()+dongnanmeneast_15_1920x1080_30_R1.xml+ImageInfo.txt 下载地址

3. 获取系统当前时间：

#include <windows.h>
#include <iostream>
using namespace std;

int main()
{
    SYSTEMTIME sys;
    GetLocalTime( &sys );
    cout<<sys.wYear<<sys.wMonth<<sys.wDay<<"_"<<sys.wHour<<sys.wMinute<<sys.wSecond<<endl;
    return 0;
}

多么美好的一天，又这么无聊的度过了。Learning efficiency is too low. Come on...beenking
