how to use Class Integer?

[Li hui]

Now, I want to use Class Integer, I generate a 512bit integer and want to transfer it 
to string or some other form that can be easy to transfered; I use encode, decode 
functions to implement it; but it seems doesn't work correctly;

below is my code:

void main()
{
        Integer *a;
        char * seed;
        seed =NULL;
        byte b;
        std::string timeSeed;
        // generate a random 512bit Integer
        if (!seed)
        {
                timeSeed = IntToString(time(NULL));
                seed = (char*)malloc(timeSeed.length());
                strcpy(seed , timeSeed.c_str());
        }
        
        GlobalRNG().Put((const byte *)seed, strlen(seed));
        a = new Integer();
        a->Randomize(GlobalRNG(),512);

        // print the Integer value
        std::string str;
        char s[64];
        int len = a->ByteCount();
        for(int i=0; i<len;i++)
        {
                b = a->GetByte(i);
                sprintf(s,"%x",b);
                printf("%x",b);
                str += s;
        }
        
        printf("\n");

        byte *tmp;

        tmp = (byte*) malloc(len);
        a->Encode(tmp,len);                             //encode a to byte array tmp

        for(i=0; i<len;i++)                             //print tmp
        {
                printf("%x",*tmp);
                tmp++;
        }
        printf("\n");

        Integer *x;
        x = new Integer();
        x->Decode(tmp,len);
        
        int r=x->Compare(*a);

        printf("compare = %i",r);       //here r is 1
