c++。以高校为基本单位进行信息存放，高校信息包括：编号、学校名称、地址、省份、建校时间等。 功能要求： 以文件形式保存相关信息，可以读取默认文件中的信息进行查询等操作。能够对高校信息进行维护：新建、修改、删除操作:.按照高校任意信息进行查询：

下面是一个简单的 C++ 程序，实现了上述要求：

#include <iostream>
#include <fstream>
#include <vector>
#include <string>

using namespace std;

// 定义高校信息结构体
struct School {
    int id;         // 编号
    string name;    // 学校名称
    string address; // 地址
    string province;// 省份
    int year;       // 建校时间

    // 构造函数
    School(int i, string n, string a, string p, int y) {
        id = i;
        name = n;

这个程序使用了一个结构体 `School` 来表示高校信息，定义了一些操作函数来实现新建、修改、删除、查询等功能。在 `main` 函数中，程序通过循环来不断接受用户的输入，根据用户选择的操作调用相应的操作函数。同时，程序在启动时会读取文件中保存的高校信息，退出时会将修改后的高校信息保存到文件中。
