Thread: Delettion of node in singly linked list

Please help me in inserting delete function it

Code:

#include<stdio.h>
#include<malloc.h>

struct node
{
     int data;
     struct node *next;
}*start;

int insert(int num)
{
     struct node *a;
     a=(struct node*)malloc(sizeof(struct node));
     a->data=num;
     a->next=start;
     a=start;
}

int display()
{
    while(start->next!=NULL)
    {
         printf("%d",start->data);
     }
}

main()
{
   start=NULL;
   insert(20);insert(30);insert(40);
   display;
}

Code:

a=start;

should be

Code:

start=a;

and:

Code:

display;

should be

Code:

display();

besides, there's no malloc.h library, malloc is in stdlib.h
