I got the solution for any Big number!!! This code is very efficient and optimized implemented by limked list..
Code:
```class Link
{
//Data Member Parts
private:
int dta;

// Function Member Parts

public:
{
;
}
{
return nxt;
}

{
return prv;
}
void ExtraInsert(Link* p);          // After Inserting
int getDta(void)
{
return dta;
}
void SetDta(int temp)
{
dta = temp;
}
int GetNoOfElem();
void DeleteMe(void);
void ClearAll(void);
};

{
int count = 0;

while(p->NxtLnk()!=NULL){
count++;
p = p->NxtLnk();
}

count++;
return count;
}

{
if(prv == NULL) { hd = this;}
p->nxt = nxt;
p->prv = this;
nxt = p;
if(p->nxt == NULL){rear = p;}
};

{
if(hd == this){ //this is the first node
return this;
}

while(p->prv != NULL){
p = p->prv;
}

return p;
}

{
if(rear == this){
return this;
}

while(p->nxt != NULL){
p = p->nxt;
}

return p;
}

//***** Start ************//
{
if(prv == NULL) // First Element
{
nxt->prv = NULL;
hd = nxt;  // Next will be first one
delete this;
return;
}
if(nxt == NULL)
{
prv->nxt = NULL; // last node
rear = prv; //Previous node will be first
return;
}
prv->nxt = nxt;
delete this;
}
//****  End Of Function*******//

{
while(p1->NxtLnk() != NULL){
p2 = p1;
p1 = p1->NxtLnk();
delete p2;
}
delete p1;
};

int main()
{
int n;// remainder
int cy  // Carried over
int rst;
int N;

cout<<"Plz input the number:";
cin>>N;
for(int n=1;n<=N;n++)
{
rn = carry = 0;

while(p->NxtLnk() != NULL)
{
rst = p->getDta()*n+cy
if(rst>=10){
rn = rst%10;
carry = rst/10;
p->SetDta(rn);
}
else
{
p->SetDta(rst);
}
p = p->NxtLnk();
carry = rst/10;
}
rst = p->getDta()*n+cy

//Other allocated memory for carried over
while(rst >= 10){
p->SetDta(rst%10);//rnder
rst = rst/10;
p = p->NxtLnk();
}
p->SetDta(rst);
}

p = p->ToRear();
while(p->PrvLnk()!=NULL)
{
cout<<p->GetDta();
p=p->PrvLnk();
}
cout<<p->GetDta()<<endl;
int num = p->GetNoOfElem();
if(num >=5)
{
p = p->ToRear();
cout<<endl<<"Or"<<endl<<endl;

cout<<p->GetDta()<<".";
p = p->PrvLnk();

for(int i=1;i<5;i++)
{
cout<<p->GetDta();
p = p->PrvLnk();
}
cout<<"E"<num-1<endl;
}
p->ClearAll();
return 0;
}```
