PHP栈的定义、入栈出栈方法及基于堆栈实现的计算器完整实例
好的,以下是用 C 语言实现的顺序栈和循环队列的完整代码和运行结果。
顺序栈的实现:
```c
#include <stdio.h>
#include <stdlib.h>
#define MAXSIZE 100
typedef struct {
int data[MAXSIZE];
int top;
} SeqStack;
void init_seqstack(SeqStack *s) {
s->top = -1;
}
int is_seqstack_full(SeqStack *s) {
return s->top == MAXSIZE - 1;
}
int is_seqstack_empty(SeqStack *s) {
return s->top == -1;
}
void push(SeqStack *s, int data) {
if (is_seqstack_full(s)) {
printf("Stack is full!\n");
exit(1);
}
s->data[++s->top] = data;
}
int pop(SeqStack *s) {
if (is_seqstack_empty(s)) {
printf("Stack is empty!\n");
exit(1);
}
return s->data[s->top--];
}
int peek(SeqStack *s) {
if (is_seqstack_empty(s)) {
printf("Stack is empty!\n");
exit(1);
}
return s->data[s->top];
}
int bracket_match(char *expr) {
SeqStack s;
init_seqstack(&s);
while (*expr != '\0') {
if (*expr == '(' || *expr == '[' || *expr == '{') {
push(&s, *expr);
} else if (*expr == ')' || *expr == ']' || *expr == '}') {
if (is_seqstack_empty(&s)) {
return 0;
}
char c = pop(&s);
if ((*expr == ')' && c != '(') ||
(*expr == ']' && c != '[') ||
(*expr == '}' && c != '{')) {
return 0;
}
}
expr++;
}
return is_seqstack_empty(&s);
}
int main() {
SeqStack s;
init_seqstack(&s);
push(&s, 1);
push(&s, 2);
push(&s, 3);
printf("Top element: %d\n", peek(&s));
printf("Pop element: %d\n", pop(&s));
printf("Pop element: %d\n", pop(&s));
printf("Pop element: %d\n", pop(&s));
printf("Stack is empty: %d\n", is_seqstack_empty(&s));
printf("Stack is full: %d\n", is_seqstack_full(&s));
char *expr1 = "((()))";
char *expr2 = "(()))";
printf("Bracket match: %d\n", bracket_match(expr1));
printf("Bracket match: %d\n", bracket_match(expr2));
return 0;
}
```
运行结果界面:
```
Top element: 3
Pop element: 3
Pop element: 2
Pop element: 1
Stack is empty: 1
Stack is full: 0
Bracket match: 1
Bracket match: 0
```
循环队列的实现:
```c
#include <stdio.h>
#include <stdlib.h>
#define MAXSIZE 6
typedef struct {
int data[MAXSIZE];
int front;
int rear;
} CircularQueue;
void init_circularqueue(CircularQueue *q) {
q->front = q->rear = 0;
}
int is_circularqueue_full(CircularQueue *q) {
return (q->rear + 1) % MAXSIZE == q->front;
}
int is_circularqueue_empty(CircularQueue *q) {
return q->front == q->rear;
}
void enqueue(CircularQueue *q, int data) {
if (is_circularqueue_full(q)) {
printf("Queue is full!\n");
exit(1);
}
q->data[q->rear] = data;
q->rear = (q->rear + 1) % MAXSIZE;
}
int dequeue(CircularQueue *q) {
if (is_circularqueue_empty(q)) {
printf("Queue is empty!\n");
exit(1);
}
int data = q->data[q->front];
q->front = (q->front + 1) % MAXSIZE;
return data;
}
int get_front(CircularQueue *q) {
if (is_circularqueue_empty(q)) {
printf("Queue is empty!\n");
exit(1);
}
return q->data[q->front];
}
int get_rear(CircularQueue *q) {
if (is_circularqueue_empty(q)) {
printf("Queue is empty!\n");
exit(1);
}
return q->data[(q->rear - 1 + MAXSIZE) % MAXSIZE];
}
void print_yanghui_triangle(int n) {
CircularQueue q;
init_circularqueue(&q);
enqueue(&q, 1);
for (int i = 1; i <= n; i++) {
int num = 0;
for (int j = 0; j < i; j++) {
int front = dequeue(&q);
enqueue(&q, num + front);
num = front;
printf("%d ", num);
}
printf("\n");
}
}
int main() {
CircularQueue q;
init_circularqueue(&q);
enqueue(&q, 1);
enqueue(&q, 2);
enqueue(&q, 3);
printf("Front element: %d\n", get_front(&q));
printf("Rear element: %d\n", get_rear(&q));
printf("Dequeue element: %d\n", dequeue(&q));
printf("Dequeue element: %d\n", dequeue(&q));
printf("Dequeue element: %d\n", dequeue(&q));
printf("Queue is empty: %d\n", is_circularqueue_empty(&q));
printf("Queue is full: %d\n", is_circularqueue_full(&q));
print_yanghui_triangle(5);
return 0;
}
```
运行结果界面:
```
Front element: 1
Rear element: 3
Dequeue element: 1
Dequeue element: 2
Dequeue element: 3
Queue is empty: 1
Queue is full: 0
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
```
