实在是没着拉
一个机子一个运行结果！！
关键那个机子的运行结果都不对
程序介绍：这个程序运用是最简单的压缩方法，数据：2222压缩成 4 2 分成2个文件分装
这种方法处理完成后再连接两个文件（这一部我的程序没有写）
源程序：
#include <stdio.h>
int reduce(char *file_name); /*压缩一个文件*/
int dell_fill(char *file1_name,char *file2_name);/*删除两个文件*/
int re_file(char *file1_name,char *file2_name);/*解压缩两个文件*/
main()
{
char *file_name="E:\\file.txt";
reduce(file_name);
puts("\nend!");
getch();
}
int reduce(char *file_name)
{
FILE *fp,*fp1,*fp2;
long fnum=0;
int f=0,f_h=1,flag,i;
char *file1_name,*file2_name;
if((fp=fopen(file_name,"rb"))==NULL)
{
printf("Open the \"%s\" error!",file_name);
getch();
exit(1);
}
i=0;
flag=0;
do
{
if(file_name[i]=='.')
{
file1_name[i]='a';
file1_name[i+1]='.';
file2_name[i]='b';
file2_name[i+1]='.';
flag=1;
}
else
{
file1_name[i+flag]=file_name[i];
file2_name[i+flag]=file_name[i];
}
}while(file_name[i++]!=0);
if(!flag)
{
file1_name[i]='a';

if(f_h==f)
{

}
else

fputc(f_h,fp2);

？？？？？？
