问题:

解答:

#include <iostream>
#include <string>
#include <fstream>
using namespace std;typedef struct _Donor
{string name;double money;
}Donor;int main()
{ifstream file;string filename;int count = 0;cout << "请输入文件名:";getline(cin, filename);file.open(filename);if (!file.is_open()){cout << "文件打开失败!" << endl;exit(EXIT_FAILURE);}bool empty = true;;file >> count;Donor* donors = new Donor[count];file.get();for (int i = 0; i < count; i++){getline(file, donors[i].name);file >> donors[i].money;file.get();}cout << "重要捐款人的信息如下:" << endl;for (int i = 0; i < count; i++){if (donors[i].money >= 10000){cout << donors[i].name << endl;empty = false;}}if (empty){cout << "NONE" << endl;}cout << "普通借款人信息如下:" << endl;for (int i = 0; i < count; i++){if (donors[i].money < 10000){cout << donors[i].name << endl;empty = false;}}if (empty){cout << "NONE" << endl;}return 0;
}

运行结果:

考查点:

• 文件的读入

注意:

• get()的用处
