刚才尝试写一个让‘@’字符上下左右移动的代码，但是出错了！！大佬们扶一把吧，下面是代码

#include <bits/stdc++.h>
using namespace std;
int x = 0, y = 0;
char maze[100][100];
void print() {
	for (int i = 0; i < 10; i++) {
		for (int j = 0; j < 10; j++) {
			cout << maze[i][j];
		}
		cout << endl;
	}
}
int main() {
	system("cls");
    for (int i = 0; i < 10; i++) {
    	for (int j = 0; j < 10; j++) {
    		if (i == 0 && j == 0) maze[i][j] = '@';
    		else maze[i][j] = '#';
		}
	}
	for (int i = 0; i < 10; i++) {
    	for (int j = 0; j < 10; j++) {
    		cout << maze[i][j];
		}
		cout << endl;
	}
	while (1) {
		char ch;
		cin >> ch;
		if (ch == 'w') {
			maze[x][y + 1] = '@';
			maze[x][y] = '#';
			y += 1;
			system("cls");
			print();
		}
		if (ch == 's') {
			maze[x][y - 1] = '@';
			maze[x][y] = '#';
			y -= 1;
			system("cls");
			print();
		}
		if (ch == 'a') {
			maze[x - 1][y] = '@';
			maze[x][y] = '#';
			x -= 1;
			system("cls");
			print();
		}
		if (ch == 'd') {
			maze[x + 1][y] = '@';
			maze[x][y] = '#';
			x += 1;
			system("cls");
			print();
		}
	}
	return 0;
}
