C语言中的一个链表！

struct element
{
 char name[20];
 char pwd[8];
 struct element* next;
};
struct element* newElement(char * name ,char * pwd)
{
 struct element* p = (struct element*)malloc(sizeof(struct element));
 memset(p,'/0',sizeof(struct element));
 strcpy(p->name,name);
 strcpy(p->pwd,pwd);
 p->next=0;
 return p;
}
int add(struct element * head,struct element* ele)
{
 if(head == 0)
 {
  head=ele;
  return 1;
 }
 while(head->next!=0)
 {
  head=head->next;
 }
 head->next=ele;
 return 1;
}
struct element* search(struct  element * head ,char * name)
{
 if(head == 0) return 0;
 while(head->next != 0)
 {
  printf("%d/n",head);
  if(strcmp(head->name,name)==0) return head;
  
        head= head->next;
  
  
 } 
 return 0;
}
int main()
{
 struct element* e1= newElement("meng","123456");
 struct element* e2= newElement("song","123123");
 struct element* e3= newElement("li","123321");
 printf("%d,%d/n",add(e1,e2),add(e1,e3));
 struct element* e4= search(e1,"song");
    printf("song pwd is :%s/n",e4->pwd);
}
以上代码在gcc编译器中编译通过，但运行出错！！，在cl编译器中运行出错！！
