Dynamic programming woes

Hello all, I've been working on a dynamic programming problem, and I can't for the life of me find my bug. Any help would be much appreciated. I don't have the full problem statement, but basically you are given 0HAVE to use only 3 packages, and the total weight of the three packages must be <= 10. It's in C++

#include<iostream>
using namespace std;
int main()
{
    //ifstream fin("in.txt");
    //ofstream fout("out.txt");
    //Set up
    int dp[3][100]; //max value from 3 weights
    int total;
    cin >> total;
    int w[total];
    int v[total];
    for (int i = 0; i < 3; i++)
        for (int j = 0; j < 100; j++)
            dp[i][j] = -1;
    //Initialize table to 0, read input
    dp[0][0] = 0;
    for (int i = 0; i < total; i++)
       cin >> w[i] >> v[i];
    //DP table
    for(int j = 1; j < total; j++)
    {
        for(int i = 3; i > 1; i--)     
        {
            for (int k = 10; k > w[j]; k--)   
            {
                if (dp[i-1][k-w[j]] != -1 && dp[i-1][k-w[j]] + v[j] > dp[i][k])
                    dp[i][k] = dp[i-1][k-w[j]] + v[j];
            }
        }
    }
    int best = -1;
    int best_weight;
    for (int i = 0; i < 10; i++)
    {
        if(dp[3][i] > best)
        {
            best = dp[3][i];
            best_weight = i;
        }
    }
    if (best != -1)
        printf("%d %d\n", best_weight, best);
    else
        printf("Impossible.\n");
    getchar();
    getchar();
    return 0;
}
