C-PROGRAM-ON-SINGLY-LINKED-LIST 首先,我们需要创建一个单向链表(SLL)的数据结构,包括USN、Name、Branch、Sem、PhNo等字段。然后,我们需要实现一个菜单驱动的程序,用于执行以下操作: 1. 创建N个学生数据的SLL。 2. 显示SLL的状态和节点数量。 3. 在SLL末尾插入/删除节点。
printf("List is Empty\n"); else{ printf("Enter the number to delete : "); scanf("%d",&num); if(delete(num)) printf("%d deleted successfully\n",num); else printf("%d not found in the list\n",num); } break; case 5: return 0; ...
