Question

I need to make a linked list that stores integer data. Also the list needs to know its size (the number of items in the list).

This is my code.

linked.h file

typedef struct node Node;
struct node{
int a;
Node* b;
};
Node m;

typedef struct {
node* head;
int size;
}list;
list list1;

Main file

#include <stdio.h>
#include "linked.h"
list init(list list1)
{
  list1.head = null;
  list1.size = 0;
  return list1;
}

void main()
{
list1=init(list1);
printf("%d",list1.size);
}

Now on running, the result is -” could not create process”,
using Turbo C on Windows.

• Why am I getting this result?
• Why is the process not being created?
• Also, is this how I should initialize a linked list?

Answer 1

There are two errors: First, you should write Node* head; rather than node* head;, and second, you should write NULL or 0 instead of null.

Probably your compiler messages are somehow suppressed.

And, yes, this is how you can initiate a linked list, but

list init(void)
{
    list list1;
    list1.head = null;
    list1.size = 0;
    return list1;
}

would be better.

And there could be made other improvements as well.
