Program bahasa C dengan Prinsip Linked List

Buatlah program (diutamakan bahasa C) yang menggunakan prinsip linked list. Isi program bebas.
Jawab :

Contoh program 1 :

#include
#include
#include
#include

class Node
{
public:
int x;
Node *ka;
};

void main()
{
clrscr();
int n,i;
Node *awal, *akhir, *temp;
awal = new Node;
akhir = awal;
cout<<"N = " ; cin>>n;
for ( i=1; i<=n; ++i)
{
temp = new Node;
temp->ka = NULL;
cout<<"Data ke " < temp = awal->ka;
while (temp->ka !=NULL)
{
cout << temp->x < temp = temp-> ka;
}
cout<< temp-> x < cout<<"Seluruh Data2\n";
temp = awal->ka;
while (temp !=NULL)
{
cout << temp->x < temp = temp-> ka;
}

int p;
cout<<"Hapus posisi ke " ; cin>>p;
Node *temp1, *temp2;
temp1 = awal;
for ( i= 1; i temp1=temp1->ka;
temp2 = temp1->ka;
temp1->ka = temp2->ka;
delete temp2;

cout<<"Seluruh Data\n";
temp = awal->ka;
while (temp !=NULL)
{
cout << temp->x < temp = temp-> ka;
}
getch();
}

Program untuk mendemostrasikan operasi linked list:
