以下是一个基本的顺序栈的C语言实现示例:

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

#define MAX_SIZE 100

typedef struct {
    int data[MAX_SIZE];
    int top;
} Stack;

void initStack(Stack *s) {
    s->top = -1;
}

int isEmpty(Stack *s) {
    return s->top == -1;
}

int isFull(Stack *s) {
    return s->top == MAX_SIZE - 1;
}

void push(Stack *s, int value) {
    if (isFull(s)) {
        printf("Stack is full\n");
        return;
    }
    s->top++;
    s->data[s->top] = value;
}

int pop(Stack *s) {
    if (isEmpty(s)) {
        printf("Stack is empty\n");
        return -1;
    }
    int value = s->data[s->top];
    s->top--;
    return value;
}

int peek(Stack *s) {
    if (isEmpty(s)) {
        printf("Stack is empty\n");
        return -1;
    }
    return s->data[s->top];
}

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

    push(&stack, 10);
    push(&stack, 20);
    push(&stack, 30);

    printf("Top element: %d\n", peek(&stack));

    printf("Popped element: %d\n", pop(&stack));
    printf("Popped element: %d\n", pop(&stack));
    printf("Popped element: %d\n", pop(&stack));

    printf("Is stack empty: %s\n", isEmpty(&stack) ? "true" : "false");

    return 0;
}

这段代码定义了一个基本的顺序栈数据结构,包括初始化栈、判断栈是否为空或满、入栈、出栈、获取栈顶元素的操作。在main函数中,进行了栈的初始化、入栈、出栈等操作,并打印了一些信息。

您可以根据自己的需求对该代码进行修改和扩展。
