C51程序设计基础** C51是专门为8051单片机设计的汇编语言,具有指令集简洁、执行效率高、资源占用少等特点。掌握C51程序设计基础是深入学习C51高级编程技术的基石。 本章将从C51程序结构、数据类型、运算符、控制语句等基础知识入手,逐步深入到数组、指针、结构体等高级数据结构,为后续章节的学习打下坚实的基础。 # 2.1 链表与栈 ### 2.1.1 链表的创建与操作 **链表**是一种非连续存储的数据结构,其元素通过指针连接起来。链表中的每个元素称为节点,每个节点包含数据和指向下一个节点的指针。 **创建链表** ```c struct node { int data; struct node *next; }; struct node *head = NULL; // 头指针,指向链表的第一个节点 ``` **插入节点** ```c void insert_node(int data) { struct node *new_node = (struct node *)malloc(sizeof(struct node)); new_node->data = data; new_node->next = head; head = new_node; } ``` **删除节点** ```c void delete_node(int data) { struct node *current = head; struct node *previous = NULL; while (current != NULL) { if (current->data == data) { if (previous == NULL) { head = current->next; } else { previous->next = current->next; } free(current); break; } previous = current; current = current->next; } } ``` **遍历链表** ```c void traverse_list() { struct node *current = head; while (current != NULL) { printf("%d ", current->data); current = current->next; } } ``` ### 2.1.2 栈的实现与应用 **栈**是一种后进先出(LIFO)的数据结构。栈中的元素通过一个指针(栈顶指针)进行访问,新元素总是被压入栈顶,而旧元素则从栈顶弹出。 **创建栈** ```c struct stack { int *arr; int top; int size; }; struct stack *create_stack(int size) { struct stack *new_stack = (struct stack *)malloc(sizeof(struct stack)); new_stack->arr = (int *)malloc(size * sizeof(int)); new_stack->top = -1; new_stack->size = size; return new_stack; } ``` **压栈** ```c void push(struct stack *stack, int data) { if (stack->top == stack->size - 1) { printf("Stack overflow\n"); return; } stack->arr[++stack->top] = data; } ``` **弹栈** ```c int pop(struct stack *stack) { if (stack->top == -1) { printf("Stack underflow\n"); return -1; } return stack->arr[stack->top--]; } ``` **应用** 栈在计算机科学中有着广泛的应用,例如: * 表达式求值 * 函数调用 * 内存管理 * 递归算法 # 3.1 中断与定时器 **3.1.1 中断处理机制** 中断是一种硬件机制,当外部事件或系统内部事件发生时,中断控制器会向CPU发出中断信号,迫使CPU暂停当前正在执行
