怎么对当前目录下文件夹内的文件遍历

[fujingn188]

如题

[llf_hust]

函数名: findfirst, findnext
功 能: 搜索磁盘目录; 取得下一个匹配的findfirst模式的文件
用 法: int findfirst(char *pathname, struct ffblk *ffblk, int attrib);
int findnext(struct ffblk *ffblk);
程序例:

/* findnext example */

#include <stdio.h>
#include <dir.h>

int main(void)
{
struct ffblk ffblk;
int done;
printf("Directory listing of *.*\n");
done = findfirst("*.*",&ffblk,0);
while (!done)
{
printf(" %s\n", ffblk.ff_name);
done = findnext(&ffblk);
}

return 0;
}

#include<iostream>

#include<io.h>
using namespace std;
void filesearch(string path,int layer)
{
struct _finddata_t filefind;
string curr=path+"\\*.*";
int done=0,i,handle;
if((handle=_findfirst(curr.c_str(),&filefind))==-1)return;
while(!(done=_findnext(handle,&filefind)))
{
if(strcmp(filefind.name,".."))//不返回
{
if ((_A_SUBDIR==filefind.attrib))
{
for(i=0;i<layer;i++)cout<<" ";
cout<<filefind.name<<"(dir)"<<endl;
curr=path+"\\"+filefind.name;
filesearch(curr,layer+1);
}
else
{
for(i=0;i<layer;i++)cout<<" ";
cout<<filefind.name<<endl;
}
}
}
_findclose(handle);
}
int main()
{
string path;
cout<<"请输入目录"<<endl;
cin>>path;
filesearch(path,0);
system("PAUSE");
return 0;
}

好..学习了..这学期学OS估计能用到

[du51]

OS用不到.OS我特别喜欢.学得算是比较用功的.
主要是进程那一块.内存那一块.

[Rick_ang]

我看了我们的课本..有一个项目是做一个Shell..其中就有要求类似DOS中输入Dir 显示当前目录的功能..正干瞪眼呢呵呵..我也很喜欢OS..
