1、先完成找毙阅泥文件的函数：
void GetFileInDir(string dirName)
{
DIR *Dir=NULL;
struct dirent *file=NULL;
if(dirName[dirName.size()-1]!='/')
{
dirName+="/";
}
if((Dir=opendir(dirName.c_str()))==NULL)
{
cerr<<"Can't open Directory"<<endl;
exit(1);
}
while(file=readdir(Dir))
{
//if the file is a normal file
if(file->d_type==DT_REG)
{cout<民良<dirName+file->d_name<<endl;
}
//if the file is a directory
else if(file->d_type==DT_DIR&&strcmp(file->d_name,".")!=0&&strcmp(file->d_name,"..")!=0)
{
GetFileInDir(dirName+file->d_name);
}
}
}
2、加入main函数
相应的main 函数：
int main(int argc,char*argv[])
{
if(argc<2)
{
cerr<<"NeedDirectory"<<endl;
exit(1);
}
string dir=argv[1];
GetFileInDir(dir);
}
3、随后加入要找的文件，从main 函数中穿参数到函数GetFileInDir
GetFileInDir(dir, filename)
然后再GetFileInDir 函数中多加一个文件是否找互海到的判断
GetFileInDir
