10个比较经典的C++程序。初学者就先多学习学习别人吧。

#include "book.h"
void main( )

	fstream iofile("booksFile.bin",ios::binary|ios::in|ios::out );
	if (! iofile)	{  cerr << "Cannot open File!" << endl;       return;	}
   	while ( 1 )
   	{	cout<<"************BookStore Management system***********\n"
         << "1 :append \t2 :sale \t3 : inquire \t4 :createtxt \t0 :exit >> ";
	   	cin >> choice;
	   	switch ( choice )
	   	{ case 1 : ob.Append(iofile); break;
	   	  case 2 : ob.Sale(iofile); break;
	   	  case 3 : ob.Inquire(iofile); break;
