To add data in singly
link list
Using following technique we can easily add data in single link
list
#include<iostream>
#include<conio.h>
using
namespace std;
struct link
{
link *next;
};
//Defined a
Structure
class
List // where we create the links
and combin them in a list
{
private:
link *first; // Head start or here its name is
first...
public:
List()
{
first=NULL; // null as link list is empty
}
void add(int d)
{
link *ptr,*temp;
if(first==NULL)// will execute only
once as when we will add first element as first is null.
{
first=new link; // vvimp steps. Create a structure, and
reference will updated have a close look at first.
first->data=d; // assign value of d come from main
function to first of data.
first->next=NULL; // Assign null
}
else
{
ptr=first;
while(ptr->next!=NULL)
{
ptr=ptr->next;// same
as increment statement as it moves toward null
}
temp=new link; // these three lines add new
elements
temp->data=d;
temp->next=NULL;
ptr->next=temp; // link the nodes with previous ones....
}
};
int main(){
List l;
l.add(20);
l.add(30);
l.add(40);
l.add(50);
getch();
}
