Thread: Struct and Malloc Help

Code:

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

struct nodePayload{
 int number;
};

struct node{
 struct nodePayload *payload;
 struct node *next;
} *headSingle, *tailSingle, *temp;

s_display_inorder(){
  tailSingle->next = NULL;
  temp = headSingle;
  printf("\nSingle list:\n");
  while (temp != NULL){
   printf("Left to right output:\t%d\n", temp->payload->number);
   temp = temp->next;
  }
}

s_add(int z){

  temp->payload = malloc(sizeof(struct nodePayload));
  temp = malloc(sizeof(struct node)); //Crashes here
  
  temp->payload->number = z;
  
  if (headSingle == NULL){
   headSingle = temp;
   tailSingle = temp;
  }
  else{
    headSingle->next = temp;
    tailSingle = temp;
  }
  return;
}

main(int argc, char *argv[]){
 headSingle = NULL;
 tailSingle = NULL;
 
 int i;
 
 for (i=0; i<10; i++){
  s_add(1);
 }
 
  s_display_inorder();

}

I just want it to put the nodes in a linked list.
