给出含有n个学生的成绩表 每条记录由学号 姓名 和分数组成 设计程序完成下列操作 设计一个菜单操作界面 该系统操作需要1.录入学生基本信息 2.直接插入排序 3.折半排序 4.冒泡排序 5.快速排序 6.简单选择排序 7.输出学生信息 8.退出

以下是一个C++程序，用于实现上述功能：

#include <iostream>
#include <string>
using namespace std;

    string id;  // 学号
    string name;  // 姓名
    int score;  // 分数
};

    Student key;
    for (i = 1; i < n; i++) {
        key = arr[i];
        j = i - 1;

        while (j >= 0 && arr[j].id > key.id) {
            arr[j + 1] = arr[j];
            j = j - 1;
        }
        arr[j + 1] = key;
    }
}

    int i, j, low, high, mid;
    Student key;
    for (i = 1; i < n; i++) {
        key = arr[i];
        low = 0;
        high = i - 1;
        while (low <= high) {
            mid = (low + high) / 2;
            if (arr[mid].id > key.id) {
                high = mid - 1;
            }
            else {

            }
        }

    }
}

            }
        }
    }

            i++;

    }

    return (i + 1);
}

该程序使用`struct`定义了一个名为`Student`的结构体，其中包含学号、姓名和分数三个属性。程序使用一个`while`循环来提供菜单操作界面，通过`switch`语句对用户的选择进行响应。对于每个排序算法，程序定义了一个相应的函数，用于对学生信息数组进行排序。`printStudents`函数用于输出学生信息。
