Sarah Rastkar，您好！
3x for your reply,but it seems your code does not
work
here is the code as your way:
Integer bbb;
bbb.Randomize(GlobalRNG(),512);
ostrstream
stream;
char *p;
stream << bbb <<
ends;
int l= stream.pcount();
p =
(char*)malloc(stream.pcount());
p=stream.str();
but it has error when compile:
error C2678: binary '<<' : no operator defined which takes a
left-hand operand of type 'class ostrstream' (or there is no acceptable
conversion)
Error executing cl.exe.

This may work:
ostrstream
stream;
stream << AnInteger << ends;
return
stream.str();

Subject: how to use Class
Integer?
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
