如何用c++实现随机生成名字

Question

用c++实现随机生成100个中文名字和成绩，用来后续的排序和查找

Answer 1

#include <iostream>
#include <string>
#include <cstdlib>
#include <ctime>

using namespace std;

const int MAX_NUM = 100; // 最大生成人数

// 结构体：记录一个学生的姓名和成绩
struct Student {
    string name; // 姓名
    int score; // 成绩
};

// 随机生成一个汉字
string randomChineseChar() {
    static const char* firstCharList[] = {
        "王", "李", "张", "刘", "陈", "杨", "赵", "黄", "周", "吴",
        "徐", "孙", "胡", "朱", "高", "林", "何", "郭", "马", "罗"
    };
    static const int firstCharNum = sizeof(firstCharList)/sizeof(char*);
    static const char* secondCharList[] = {
        "一", "二", "三", "四", "五", "六", "七", "八", "九", "十",
        "莉", "芳", "婷", "敏", "静", "娟", "丽", "华", "洁", "雯",
        "军", "勇", "华", "强", "明", "亮", "鹏", "志", "飞", "龙"
    };
    static const int secondCharNum = sizeof(secondCharList)/sizeof(char*);

    int firstIndex = rand() % firstCharNum;
    int secondIndex = rand() % secondCharNum;
    return string(firstCharList[firstIndex]) + string(secondCharList[secondIndex]);
}

// 随机生成一个名字
string randomName() {
    string firstName = randomChineseChar();
    static const char* secondNameList[] = {
        "丽", "磊", "峰", "敏", "华", "强", "明", "红", "娟", "伟",
        "芳", "婷", "静", "洁", "雯", "龙", "志", "飞", "鹏", "欣"
    };
    static const int secondNameNum = sizeof(secondNameList)/sizeof(char*);

    int secondIndex = rand() % secondNameNum;
    return firstName + string(secondNameList[secondIndex]);
}

// 随机生成一个成绩
int randomScore() {
    return rand() % 101; // 成绩在0到100之间
}

int main() {
    srand(time(nullptr));

    Student students[MAX_NUM];
    for (int i = 0; i < MAX_NUM; ++i) {
        students[i].name = randomName();
        students[i].score = randomScore();
    }

    // 输出排序前的学生名单
    cout << "排序前的学生名单：" << endl;
    for (int i = 0; i < MAX_NUM; ++i) {
        cout << "姓名：" << students[i].name << "\t成绩：" << students[i].score << endl;
    }

    // 这里可以加上对学生成绩进行排序和查找的代码

    return 0;
}

使用rand()函数来随机生成汉字、成绩等数据，具体实现方式可以参考randomChineseChar()、randomName()、randomScore()函数的实现。建立一个Student结构体用来存储每个学生的姓名和成绩，使用如下代码生成随机数据，并输出排序前的学生名单:

// 随机生成学生信息
for (int i = 0; i < MAX_NUM; ++i) {
    students[i].name = randomName();
    students[i].score = randomScore();
}

// 输出排序前的学生名单
cout << "排序前的学生名单：" << endl;
for (int i = 0; i < MAX_NUM; ++i) {
    cout << "姓名：" << students[i].name << "\t成绩：" << students[i].score << endl;
}

在输出排序前的学生名单之后，你可以添加具体的排序算法和查找代码，这里不再赘述。
