Hi
Does anybody knows what is wrong with taht code? Why it says it is empty link list? It should fill with the numbers I enter. Could anybody help to answer the question?
Thanks
#include<stdio.h>
#include<conio.h>
struct Node
{
int number;
struct Node *link;
};
typedef struct Node* NodePtr;
void printNode(NodePtr head);
void insertNode(NodePtr *head,int numb);
int main(void)
{
NodePtr head;
int data;
head=NULL;
printf("\nWhat is the number : ");
scanf("%d", &data);
while(data>0)
{
insertNode(&head,data);
printNode(head);
printf("\nWhat is the number : ");
scanf("%d", &data);
}
getch();
return 0;
}
void printNode(NodePtr head)
{
if (head==NULL)
printf("The linked lists is NULL");
else
{
printf("The nodes contain the numbers: \n");
while (head!=NULL)
{
printf("%d -->",head->number);
head=head->link;
}
printf(" NULL");
}
}
void insertNode(NodePtr *head,int numb)
{
NodePtr newPtr;
NodePtr previousPtr;
NodePtr currentPtr;
newPtr=malloc(sizeof(struct Node));
newPtr->number=numb;
newPtr->link=NULL;
previousPtr=NULL;
currentPtr=*head;
while(currentPtr!=NULL && numb>currentPtr->number)
{
previousPtr=currentPtr;
currentPtr=currentPtr->link;
}
if (previousPtr==NULL)
{
newPtr->link=currentPtr;
currentPtr=newPtr;
}
else
{
previousPtr->link=newPtr;
newPtr->link=currentPtr;
}
}
