把整个代码分成很多小模块，初始化模块，显示模块，调整模块，运行模块。还望大牛能给出进一步优化的建议和改进。代码如下：

#include<iostream>
#include<string>
#include<vector>
#include<ctime>
using namespace std;
#define row 10
#define col 10
int score = 0;
int cnt = 0;
vector<vector<bool>>state(row, vector<bool>(col, false));
vector<vector<int>>nums(row, vector<int>(col, 0));
void display()
{
    for (int i = 0; i < row; i++)
    {
        for (int j = 0; j < col; j++)
        {
            if (!state[i][j])
            cout << nums[i][j] << " ";
            else cout << "  ";
        }
        cout << endl;
    }
    cout << "your score is :" << score << endl;
}
void initgame()
{
    srand(time(0));
    for (int i = 0; i < row; i++)
    {
        for (int j = 0; j < col; j++)

            state[i][j] = false;
            nums[i][j] = rand() % 3;
        }

    }
    display();
}

    return true;
