my code is:
#include<stdio.h>
#include<iostream.h>
struct node
{
int info;
struct node *next;
};
typedef struct node *nodeptr;
nodeptr i;
nodeptr q;
nodeptr p;
nodeptr *plist;

nodeptr getnode(void)
{
nodeptr p;
p=(nodeptr)malloc(sizeof(struct node));
return p;
}
void freenode(nodeptr p)
{
free(p);
}





int main()
{
int i;
nodeptr *k;
int a;
int r;
nodeptr end;

p=getnode();
q=getnode();


for(i=0; i<3; i++)
{
q=*k;
cout<<"enter value";
cin>>r;

p->info=r;
q->next=p;
q=q->next;
}

for(q=*k; q->next!=NULL; q=q->next)
cout<<(q->next)->info;

return 0;
}

here when i input three nos
in the output the last no is only shown
can yu suggest me what is wrong in the code
please help

Please use code tags. :)

Chances are good your compiler warns you about using an uninitialized variable. Pay attention to your compiler warnings.

Maybe not though, since your code suggests you're using a pre-standard C++ compiler. In which case, upgrade.

Get out of the habit of using global variables. It may not seem like a bad thing now, and it probably isn't in a small program like this, but trust me, it's not a good thing to use. Better to have getters and setters than have anything in global scope.
