不是答案，只是一个免手打模板 把示例里的结果复制过来可以生成为字符串数组赋值的语句结果放后面了可以直接加工

#include <iostream>  
#include <algorithm>  
#include <vector>  
#include <string>  
#include <cmath>  
using namespace std;
int main()
{
ios_base::sync_with_stdio(false);
	cin.tie(0);
 	cout.tie(0);
 	char c;
 	vector<vector<string>> s(5, vector<string>(10, ""));
  	
 	for (int i = 0; i < 5; i++)
 		for (int j = 0; j < 10; j++)
 		{
 			if (j == 0)
 				for (int z = 0; z < 3; z++)
 				{
 					cin >> c;
 					s[i][j] += c;
 				}
 			else
 			{
 				cin >> c;
 				for (int z = 0; z < 3; z++)
 				{
 					cin >> c;
 					s[i][j] += c;
 				}
 			}
 			cout << "s[" << i << "][" << j << "]=\"" << s[i][j] << "\";" << endl;
 		}
     return 0;
    }

这是上诉代码生成的结果
s[0][0] = "XXX";
s[0][1] = "..X";
s[0][2] = "XXX";
s[0][3] = "XXX";
s[0][4] = "X.X";
