//之前看过一篇有关文件属性及目录列表的操作。假如我们要对某一目录下的所有文件进行操作，那么不得不遇到遍历文件的问题。//下面给出遍历D盘下的所有文件的程序，同时输出了每个文件的属性。遍历其他文件则类似。 //源程序清单：#include<iostream>#include<string.h>#include<io.h>FILE *fp;using namespace std;void traval(char name[]);//遍历一个目录//int i=0;void main(){ if((fp=fopen("data.txt","w"))==NULL) {  cout<<"打开写文件失败！\n";  return; } char name[250]="D:\\*.*"; traval(name); fclose(fp);}void traval(char name[])//遍历一个目录{ char name1[250]; //cout<<name; //fprintf(fp,"%s  ****%d",name,++i); _finddata_t file; long lf; if((lf=_findfirst(name,&file))==-1l) {  cout<<"该目录不存在！\n";  fprintf(fp,"该目录不存在！\n"); } else {  while(_findnext(lf,&file)==0)  {   if(file.name[2]==0)    continue;   cout<<file.name<<"\t";   fprintf(fp,"%s\t",file.name);   if(file.attrib==0)   {    cout<<"正常 ";    fprintf(fp,"正常 ");   }   if((file.attrib%2)==1)   {    cout<<"只读 ";    fprintf(fp,"只读 ");   }   if((file.attrib==2)||(file.attrib==3)||(file.attrib==6)||(file.attrib==7)||    (file.attrib==18)||(file.attrib==19)||(file.attrib==22)||(file.attrib==23)||    (file.attrib==34)||(file.attrib==35)||(file.attrib==38)||(file.attrib==39)||    (file.attrib==50)||(file.attrib==51)||(file.attrib==54)||(file.attrib==55))   {    fprintf(fp,"%s\t",file.name);    cout<<"隐藏 ";    fprintf(fp,"隐藏 ");   }   if((file.attrib==4)||(file.attrib==5)||(file.attrib==6)||(file.attrib==7)||    (file.attrib==20)||(file.attrib==21)||(file.attrib==22)||(file.attrib==23)||    (file.attrib==36)||(file.attrib==37)||(file.attrib==38)||(file.attrib==39)||    (file.attrib==52)||(file.attrib==53)||(file.attrib==54)||(file.attrib==55))   {    cout<<"系统 ";    fprintf(fp,"系统 ");   }   if((file.attrib>=32&&file.attrib<=55))   {    cout<<"存档 ";    fprintf(fp,"存档 ");   }   if((file.attrib>=16&&file.attrib<=23)||(file.attrib>=48&&file.attrib<=55))   {    cout<<"文件夹 ";    cout<<endl;    fprintf(fp,"文件夹\n");    strcpy(name1,name);    name[strlen(name)-3]='\0';//最后三个字符去掉    name=strcat(name,file.name);//    name=strcat(name,"\\*.*");    cout<<endl<<name<<endl;    //fprintf(fp,"\n%s\n",name1);    traval(name);    strcpy(name,name1);   }   else   {    cout<<endl;    fprintf(fp,"\n");   }  } } _findclose(lf);}
