用c++写一个单词填空，给定中文释义和部分字母的代码

以下是一个简单的示例程序，可以让用户根据给定的中文释义和部分字母填写单词。

#include <iostream>
#include <string>

using namespace std;

int main() {
    // 给定的中文释义和部分字母
    string definition = "一种动物，有长长的脖子和腿，可以伸长到高处的树枝上吃树叶。";
    string letters = "g_r__e_";

    // 题目答案
    string answer = "giraffe";

    // 输出题目
    cout << "请填写下列单词：" << endl;
    cout << definition << endl;
    cout << letters << endl;

    // 用户输入答案
    string userAnswer;
    cin >> userAnswer;

    // 判断用户答案是否正确
    if (userAnswer == answer) {
        cout << "恭喜你，回答正确！" << endl;
    } else {
        cout << "很遗憾，回答错误。正确答案是：" << answer << endl;
    }

    return 0;
}

程序会先输出给定的中文释义和部分字母，然后让用户输入答案。最后判断用户答案是否正确，并输出相应结果。

编写c++程序开发一个单词记忆和考核系统。具有如下基本功能：支持文件导入中英文词典导入能够滚动播放单词，并且设定播放总时长和播放间隔能设定词汇范围（四六级、考研、托福）能进行如下方式的考核：听写单词填空，给定中文释义，和部分字母中英翻译（选择题）能记录每次考核的情况，能记录考核错误单词，并优先选择错误单词能记录个人使用轨迹，如使用时长，单词范围等，给设计鼓励体系，在不同的阶段颁发不同的鼓励勋章。
