本文实例讲述了C语言按关键字搜索文件夹中文件的方法。分享给大家供大家参考。具体实现方法如下：

方法1：

#include<iostream>#include<string>#include<io.h>using namespace std;void filesearch(string path,string mode){ struct _finddata_t filefind; if(path[path.size()-1]=='\\') path.resize(path.size()-1); string curr=path+"\\*.*"; int done=0,handle; if((handle=_findfirst(curr.c_str(),&filefind))==-1) return; while(!(done=_findnext(handle,&filefind))) { if(!strcmp(filefind.name,"..")) continue; curr=path+"\\"+filefind.name; if(strstr(filefind.name,mode.c_str())) cout<<curr<<endl; if (_A_SUBDIR==filefind.attrib) filesearch(curr,mode); } _findclose(handle); }void main(){ string path,mode; cout<<"请输入要搜的目录"<<endl; cin>>path; cout<<"请输出包含字符"<<endl; cin>>mode; filesearch(path,mode);}

方法2：

#include<stdio.h>#include<string.h>#include<dir.h>#define SIZE 12void find_creat_file(char *);int main(void){ char filename[SIZE]; strcpy(filename,"filename"); find_creat_file(filename); getch(); return 0;}void find_creat_file(char *filename){ struct ffblk ffblk; int done; done=findfirst("d:\\filename",&ffblk,0); if(done==0) return 0; else mkdir("d:\\filename");}

希望本文所述对大家的C语言程序设计有所帮助。
