Help,I have trouble in writing a file into a buffer and anoter file!

[ArmStronger]

There is a MIDI file "hello.mid"(Size : 1M).
I want to write the data of it to a buffer and anther file.

#include "stdafx.h"
#include "stdio.h"

using namespace std;

const int nSize = 2*1024;//Max size :2M 

int _tmain(int argc, _TCHAR* argv[])
{
	FILE* pf, * pf1;
	int nLength = 0; 
	unsigned char * pBuffer = new unsigned char[nSize];
	char* strPathName = "hello.mid";
    
	if((pf = fopen(strPathName,"r"))==NULL)
	{
		cout<<"Can't open file"<<endl;
		system("pause");
		return 0;
	}

//Write data into *pBuffer
 
	while(!feof(pf))
	{		
		fread(pBuffer,sizeof(unsigned char),1,pf);
		nLength++;
		
	}
	
               //Write data into anther file named "temp.mid":
          if((pf1 = fopen("temp.mid","w+"))==NULL)
	{
		cout<<"Can't write file"<<endl;
		system("pause");
		return 0;
	}
	
	unsigned char ch=fgetc(pf);
	while(!feof(pf))  
	{
		fputc(ch,pf1); 
		ch=fgetc(pf);
                     nLength++;
	}

	fclose(pf1);  
	fclose(pf);
	
	system("pause");
	return 0;
}

Problem:
1." Temp.mid"is lager than "hello.mid",in other words, "temp.mid" has
indescribable redundant data, why?
2. Why can't "temp.mid" be generated in this way :
fwrite(pBuffer,sizeof(unsigned char),nLength,pf1); ?

Thanks!

Midi are binary files and you're opening it as text. Read and write it binary.
