学生管理系统主菜单的操作优化，该优化后的区别在于可以通过键盘上的w和s键来控制程序中的<<的移动。
其中_getch()函数功能为获取键盘输入，不同于cin的是cin只能输入一次而_getch()能够输入多次。若键盘没有输入则没有返回值，其头文件为conio.h。

#include<iostream>
#include <conio.h>
using namespace std;
void system_menu(int choice)
{
    cout << "* * * * * * * * * * * * * * * * *" << endl;
    cout << "*\t  学生管理系统  \t*" << endl;
    cout << "*\t\t\t\t*" << endl;
    cout << "*\t    主菜单\t\t*" << endl;
    cout << "*\t\t\t\t*" << endl;
    cout << "*\t 添加学生信息    ";
    if (choice == 1)cout << " <<\t*" << endl;
    else cout << "  \t*" << endl;
    cout << "*\t\t\t\t*" << endl;
    cout << "*\t 删除学生信息    ";
    if (choice == 2)cout << " <<\t*" << endl;
    else cout << "  \t*" << endl;
    cout << "*\t\t\t\t*" << endl;
    cout << "*\t 修改学生信息    ";
    if (choice == 3)cout << " <<\t*" << endl;
    else cout << "  \t*" << endl;
    cout << "*\t\t\t\t*" << endl;
    cout << "*\t 查找学生信息    ";
    if (choice == 4)cout << " <<\t*" << endl;
    else cout << "  \t*" << endl;
    cout << "*\t\t\t\t*" << endl;
    cout << "*\t 显示学生信息    ";
    if (choice == 5)cout << " <<\t*" << endl;
    else cout << "  \t*" << endl;
    cout << "*\t\t\t\t*" << endl;
    cout << "*\t 退出系统      ";
    if (choice == 6)cout << "   <<\t*" << endl;
    else cout << "  \t*" << endl;
    cout << "*\t\t\t\t*" << endl;
