以下是源码 自己没看出来问题出在哪

#include <iostream>
using namespace std;
int main() {
    int m=0,n=0,c=0;
    cin>>n>>m;
    char g[m+2][n+2];
    for(int i=1;i<=n;i++){
        for (int j=1; j<=m; j++) cin>>g[i][j];
    }
    for(int i=1;i<=n;i++){
        for (int j=1; j<=m; j++) {
            if (g[i][j]=='*') {
                cout<<g[i][j];
            }
            else if(g[i][j]=='?'){
                if (g[i+1][j+1]=='*') c++;
                if (g[i-1][j+1]=='*') c++;
