求围观

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
int handleF()
{
FILE *Hf;
int Fn;
Hf=fopen ("0.txt","w+");
fscanf (Hf,"%d",&Fn);
printf ("%d\n",Fn);
Fn++;
fprintf (Hf,"%d",Fn);
fclose (Hf);
printf ("%d\n",Fn);
return Fn++;
}
void NewFile()
{
FILE *NewFile;
int GetNum;
char aftF[5]=".txt";
char *NewFpath;
GetNum=handleF();
sprintf (NewFpath,"%d%s",GetNum,aftF);
printf ("%s",NewFpath);
NewFile=fopen (NewFpath,"w");
//rename ("a.txt",NewName);
fclose (NewFile);
}
int main ()
{
NewFile();
return 0;
}

无论里边的数字是几

等一等，看看有没有大神帮解问题
