I still cant figur out the formula for this problem.Can anyone give me some hints??THX a lot !!

i see,i'll try,thank u guys!!

[cpp]#include <iostream>
using namespace std;

int main()
{
int n,m,i,j,count=1,flag=0;
char a[101][101];
int b[101][101]={0};
while(cin>>n>>m)
{
if(n==0&&m==0) break;
for(i=0;i<n;i++)
for(j=0;j<m;j++)
{
cin>>a [j];
}
for(i=1;i<n-1;i++)
for(j=1;j<m-1;j++)
{
if(a [j]=='*') b [j]=9 ...

Maybe I'm not understand the problem thoroughly but I don't know how to caolculate the volumn of 2 cones.Does the cylinder in the center of "D"?

THX...

[cpp]#include <iostream.h>
#include <stdio.h>

int main()
{
int a,b,c,d,sum;
while(cin>>a>>b>>c>>d)
{
if(a==0&&b==0&&c==0&&d==0) break;
sum=1080+(120+a-2*b+2*c-d)*9;
cout<<sum<<endl;
}
return 0;
}[/cpp]

I dont know where goes wrong but I got WA all the time,can u give me some test data??thx!

I got AC~~THANK U A1!

I tried hundreds of times but still got WA in 10062,can u help me to check my code?
