	cout<<"1.查询航线2.订票业务3.退票业务4.返回主菜单5.退出系统"<<endl;
    int n;	
	cin>>n;
	switch(n){
	
	case 1:
		cout<<"查询航线"<<endl;
		break;
	case 2:
		cout<<"订票业务"<<endl;
		break;
	case 3:
		cout<<"退票业务"<<endl;
		break;
	case 4:
		cout<<"           主菜单          "<<endl;

	case 5:
		cout<<"退出系统"<<endl;
		cout<<"1.查询航线2.订票业务3.退票业务4.返回主菜单5.退出系统"<<endl;
