有关C++实现文件操作的代码

#include <iostream.h> // 文件操作必须的头文件
#include <fstream.h>
void compare_(char *sourcestr,char aimch,int fitnum,char *aimbuffer);
void main()
{
fstream  file1; // 定义一个fstream类的对象用于读
file1.open("C:\\Program Files\\Microsoft Visual Studio\\COMMON\\MSDev98\\Bin\\font_1.txt", ios::in);
if (!file1)
{ cout<<"font_1不能打开！\n"; return; }
else
cout<<"succed to open font_1\n";
fstream  file2; // 定义一个fstream类的对象用于写
file2.open("D:\\test.txt", ios::out );
    if (!file2)
{
cout<<"test.txt不能创建！\n";
file1.close(); return;
}
else
cout<<"succed to open test\n";
   char ch;
   char arry[80];
   int i=0,j=0;
   while(file1.get(ch)) //或：file1.read(&ch,1)
   {
  arry[i]=ch;
  ++i;
   }
    cout<<i<<"\n";
while(j!=i)
