C++ 转义字符

下述程序演示了一些转义序列。它使用振铃字符来提请注意，使用换行符使光标前进，使用退格字符使光标向左退一格

void bodini(void)
{
	cout<<"\aOperation \"HyperHype\" is now activated!\n";
	cout<<"Enter your agent code:_______\b\b\b\b\b\b";
	long code;
	cin>>code;
	cout<<"\aYou entered "<<code<<"...\n";
	cout<<"\aCode verified! Proceed with Plan Z3!\n"; 
}
