代码

1、用字符数组接受所有字符
2、依次检查每个非地雷格周围的地雷数

#include<bits/stdc++.h>

using namespace std;

char s[105][105];
int n,m;
void f(int x,int y);
int main(){
	int i,j;
	cin>>n>>m;
	for(i=0;i<n;i++)
		for(j=0;j<m;j++)
			cin>>s[i][j];
	for(i=0;i<n;i++){
		for(j=0;j<m;j++){
			if(s[i][j]=='?')
				f(i,j);
			cout<<s[i][j];
		}
		cout<<endl;
	}
	return 0;
}
void f(int x,int y){
	int cnt=0;
	if(x-1>=0&&y-1>=0&&s[x-1][y-1]=='*') cnt++;
	if(x-1>=0&&s[x-1][y]=='*') cnt++;
	if(x-1>=0&&y+1<=m&&s[x-1][y+1]=='*') cnt++;

	if(x+1<=n&&y+1<=m&&s[x+1][y+1]=='*') cnt++;
	s[x][y]=cnt+'0';
