Well, don't care too much about PE, if adding or taking off a newline doesn't solve it. It might be that the judge output has itself a PE compared to the theorical output (it already happened)

Anyone please help me ? Why wrong answer ???

hi zilnus... you're from bandung, rite?
looking at the code.. when i == 0 and j == 0, your code doesnt immediately break, but read input first, perhaps it can cause error..

titid

You just have to change the part:
[c]
while ((i != 0)&&(j != 0))
{
scanf("%d %d",&i,&j);
[/c]
with
[c]
while(scanf("%i %i",&i,&j)){
if(!i&&!j) break;
[/c]
That'll solve it (but very possibly with P.E.)!!

You'll have trouble when the minefield is 100x100, your matrix is too small.

Sorry for my late reply
Actually it was Compile Error,
and I am not sure why

If you use the function memset() you have to include <string.h> header file.

Thank you Subeen, but in my compiler (Borland Cpp) it's ok.
Are you talking about gcc ?

Yes, I am talking about gcc. ( and I also use BC++
)
Why WA?

I still don't know why is my code resulting WA
the sampe input and output is correct, maybe I missed something?
[c]
#include<stdio.h>
#include<string.h>
void main()
{
int n,m;
int i,j;
int k,l;
int ctr;
int num;
char mat[100][100];
num=1;
/*
freopen("input.txt","r",stdin);
freopen("output.txt","w",stdout);
*/
do
{
memset(mat,'0',sizeof(mat));
scanf("%d %d\n",&n,&m);
if(n==0 && m==0)
break;
for(i=0;i<n;i++)
{
gets(mat);
}
for(i=0;i<n;i++)
{
for(j=0;j<m;j++)
{
ctr=0;
if(mat[j]!='*')
{
for(k=i-1;k<=i+1;k++)
{
for(l=j-1;l<=j+1;l++)
{
if(mat[k][l]=='*')
ctr++;
}
}
mat[j]=ctr+'0';
}
}
}
printf("Field #%d:\n",num);
for(i=0;i<n;i++)
{
for(j=0;j<m;j++)
{
printf("%c",mat[j]);
}
printf("\n");
}
num++;
printf("\n");
}while(n!=0 && m!=0);
/*
fcloseall();
*/
}
[/c]

maybe like this :
1. array [100][101] => because of string => "aaaa\0" => NULL character
2. when i || j == 0 => k=-1 || l=-1.
3. when i || j == 100 => k=101 || l=101.
I just found this...
