Thread: error:expected declaration or statement at end of input

GO TO POST 6(is my new problem)
{
this solved
I am getting this message when i am trying to compile the code
series1.c:44: σφάλμα: expected declaration or statement at end of input
series1.c:44: σφάλμα: expected declaration or statement at end of input
where is the mistake?(maybe any missing { or })

Code:

#include <stdio.h>
#include <stdlib.h>

struct node{
  char data[64];
  struct node *next;
 };
struct node *firsta, *currenta, *newa;

int main(void)
{
 int k;
 scanf("%d", &k);

 struct node *head=NULL;

 do{
  switch(k){
   case 1: addnew();
   break;

  }while(k!=0);

 void addnew(void)
{
 struct node *newnode=malloc(sizeof(struct node));
  
 if (head=NULL) 
  firsta=newa=currenta;
 else
 {
  currenta=firsta;
   while(currenta->next!=NULL)
    currenta=currenta->next;

   currenta->next=newa;
   currenta=newa;
}

gets(currenta->data);

currenta->next=NULL;
}
