{    int i,j;char In[NUM];
scanf("%d%d",&n,&m);
for(i=0;i<=n+1;i++)
for(j=0;j<=m+1;j++)Map[i][j]=1;
for(i=1;i<=n;i++)
{ scanf("%s",In);
for(j=1;j<=m;j++)
{ Map[i][j]=(In[j-1]=='*');
if(!Map[i][j]){tx=i;ty=j;}
}
}
}
I think it's probably because you ignored the '\n' at the end of the line
try this change:

{    int i,j;char ch;
scanf("%d%d",&n,&m);
for(i=0;i<=n+1;i++)
for(j=0;j<=m+1;j++)Map[i][j]=1;
for(i=1;i<=n;i++)
{ scanf("%c",&ch);
for(j=1;j<=m;j++)
{ scanf("%c",&ch);
Map[i][j]=(ch=='*');
if(!Map[i][j]){tx=i;ty=j;}
}
}
}
I tested and both can AC this problem.
