源码整合时遇到问题了。能否指点一下。谢谢
这是自己写的一段获取当前目录文件名并且存入数组中的源码。
程序代码：#include <stdlib.h>
#include <windows.h>
void Get_FileName()
{
system("dir /b *.csv > file_name.txt");
}
int main()
{
Get_FileName();
int i=0;
char file_name[255][255];
FILE *fp;
fp=fopen("file_name.txt","r");
if(fp==NULL)
{
printf("\n error! can\'t find file_name.txt!");
getchar();
exit(0);
}
while(fscanf(fp,"%s",file_name[i])!=EOF)
i++;
fclose(fp);
for(int j=0;j<i;j++)
printf("%s\n",file_name[j]);
system("pause");
return 0;
}这是一段学长写的可以单独处理一个固定名字和输出固定名字的CSV文件的源码
程序代码：#include<fstream>
#include<iostream>
#include<sstream>
#include<map>
#include<string>
#include<cstdlib>
#include<windows.h>
using namespace std;
struct _data
{
string info;
string name;
};
class secTool
{
public:
secTool() {};
~secTool() {};
void handlefile()
{
cout << "请确保data.csv和dict.txt两个文件在本程序目录下" << endl;
system("PAUSE");
system("CLS");
ifstream fData("data.csv"), fDict("dict.txt");
while (!fData)
{
cout << "data.csv不在程序目录下或者无法打开，正在重试!" << endl;
fData.sync();
fData.clear();
Sleep(1000);
system("CLS");
fData.open("data.csv", ios::_Nocreate);
}
while (!fDict)
{
cout << "dict.txt不在程序目录下或者无法打开，正在重试!" << endl;
fDict.sync();
fDict.clear();
Sleep(1000);
system("CLS");
fDict.open("dict.txt", ios::_Nocreate);
}
string temp, id, name;
_data tData;
getline(fData, temp);
tableHead += temp + '\n';
getline(fData, temp);
tableNum = temp.size() + 1;
tableHead += temp + '\n';
getline(fData, temp);
tableHead += temp + '\n';
while (fDict >> id >> name)
{
tData.name = name;
dataMap.insert(make_pair(id, tData));
}
fDict.close();
while (!fData.eof())
{
getline(fData, temp);
int i = temp.find(',');
int j = temp.find(',', i + 1);
string t = temp.substr(i + 1, j - i - 1);
if (dataMap.count(t) > 0)
{
subNum++;
stringstream stream;
stream << subNum;
dataMap[t].info = stream.str() + temp.substr(temp.find(','), temp.size() - temp.find(','));
}
}
fData.close();
}
void outputfile()
{
map<string, _data>::iterator it;
ofstream outFile("out.csv");
if (!outFile)
{
cout << "生成out.csv文件失败！" << endl;
return;
}
outFile << tableHead;
for (it = dataMap.begin(); it != dataMap.end(); it++)
{
if (it->second.info.size() == 0)
{
outFile << ++subNum << ',' << it->first << ',' << it->second.name;
for (int i = 0; i < tableNum - 3; i++) outFile << ',';
outFile << endl;
}
else
outFile << it->second.info << endl;
}
cout << "输出文件out.csv成功！" << endl;
outFile.close();
}
private:
map<string, _data> dataMap;
string tableHead;
int tableNum ;
int subNum ;
};
int main()
{
secTool sectool;
sectool.handlefile();
sectool.outputfile();
system("PAUSE");
return 0;
}我现在想把它改成一个能够循环处理我数组里文件名的，并且输出到另一个文件夹里的工具，就是一次可以批量处理本目录下所有CSV。但是我还没有学c++,学长的代码看不懂。。改的不能够编译了。能不能帮我看一下，我哪里出问题了，谢谢。谢谢(*°∀°)=3
