用c语言，将一个顺序表的所有元素逆置

#include <stdio.h>
#define MAXSIZE 100

typedef struct {
    int data[MAXSIZE];
    int length;
} SqList;

void reverse(SqList *list) {
    int temp;
    int left = 0;
    int right = list->length - 1;
    while (left < right) {
        temp = list->data[left];
        list->data[left] = list->data[right];
        list->data[right] = temp;
        left++;
        right--;
    }
}

int main() {
    SqList list = { {1, 2, 3, 4, 5}, 5 };
    printf("Before reverse: ");
    for (int i = 0; i < list.length; i++) {
        printf("%d ", list.data[i]);
    }
    printf("\n");
    reverse(&list);
    printf("After reverse: ");
    for (int i = 0; i < list.length; i++) {
        printf("%d ", list.data[i]);
    }
    printf("\n");
    return 0;
}
