When I submit the solution for the problem I get a compilation error.
The error reads:

"You tried to solve problem 1017. Your solution on C++ was compiled
with the following errors:

143733
temp\143733(54) : error C2471: cannot update program
database 'e:\judge\vc60.pdb'"

can anyone tell me what is this about.

I am sure the problem is correctly solved and that it does no illegal
operations. Also it compiles perfectly under gcc for dos. I can't
test it with Visual C++ but I don't use anything other than ANSI so
it should be ok.

I attach the source code of my program, maybe you could indicate the
error. If the error is not with my source code, but with TIMUS, what
should I do?

#include <stdio.h>

#define MAX 501

int n;

double answer, d[MAX][MAX];

void solve()
{
    int i, j, k;

    // d[i][j] = numarul de moduri in care se pot aranja j
blocuri astfel
    // incat inaltzimea sa fie egazact j
    for (i = 1; i <= n; i++)
        for (j = 1; j <= n; j++)
            d[i][j] = 0;
    d[0][0] = 1;
    for (i = 1; i <= n; i++)
        for (j = 1; j <= n && i - j >= 0; j++)
        {
            d[i][j] = 0;
            for (k = 0; k < j; k++)
                d[i][j] += d[i - j][k];
        }
/*    for (i = 1; i <= n; i++)
    {
        for (j = 1; j <= n; j++)
            printf("%d ", d[i][j]);
        printf("\n");
    }*/
    for (k = 1; k < n; k++)
        answer += d[n][k];
}

int main()
{
/*#ifndef ONLINE_JUDGE
    freopen("staircases.in", "r", stdin);
    freopen("staircases.out", "w", stdout);
#endif*/

    scanf("%d", &n);
    solve();
    printf("%.0lf\n", answer);

/*#ifndef ONLINE_JUDGE
    fclose(stdin);
    fclose(stdout);
#endif*/

    return 0;
}

I think the problem is not with my program but with the TIMUS
computer. How can it be solved. The reason I say the problem is with
their computer is that even when I submit a wrong simple solution:

#include <stdio.h>

int main()
{
    int n;
    scanf("%d", &n);
    printf("%d", n);
    return 0;
}

i get the same result.
Can anyone help me with this, please?

in C++ it is right,but in C it will get Compilation error
