My code passed all the test cases above, but I am getting WA. Can anybody help?

#pragma warning(disable:4786)

#include<cstdio>
#include<string>
#include<cstring>
#include<vector>
#include<map>
#include<algorithm>



using namespace std;

struct type{
string name;
char name2[20];
double cost ...

i am getting WA over and over again. I've tested some of Minilek's cases and found some fault. Actually the answer is too near. I am unable to find the problem so far.
