用c语言编写一个具有进栈出栈操作的链式栈

好的，可以给您提供参考代码：

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

typedef struct node {
    int data;
    struct node *next;
} Node;

typedef struct stack {
    Node *top;
} Stack;

void init(Stack *stack) {
    stack->top = NULL;
}

int isEmpty(Stack *stack) {
    return stack->top == NULL;
}

void push(Stack *stack, int data) {
    Node *newNode = (Node*)malloc(sizeof(Node));
    newNode->data = data;
    newNode->next = stack->top;
    stack->top = newNode;
}

int pop(Stack *stack) {
    if (isEmpty(stack)) {
        printf("Error: stack is empty\n");
        return -1;
    }
    int data = stack->top->data;
    Node *temp = stack->top;
    stack->top = stack->top->next;
    free(temp);
    return data;
}

void print(Stack *stack) {
    if (isEmpty(stack)) {
        printf("Stack is empty\n");
        return;
    }
    Node *temp = stack->top;
    while (temp != NULL) {
        printf("%d ", temp->data);
        temp = temp->next;
    }
    printf("\n");
}

int main() {
    Stack stack;
    init(&stack);

    push(&stack, 1);
    push(&stack, 2);
    push(&stack, 3);

    print(&stack);

    int data = pop(&stack);
    printf("pop: %d\n", data);

    print(&stack);

    return 0;
}
