可以针对上述问题，用c语言写一段代码吗

当然可以，下面是一个简单的C语言代码片段来解决这个问题，这里假设我们使用了一个固定大小的字符数组来模拟环形队列：

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

#define MAX_PEOPLE 90

int queue[MAX_PEOPLE]; // 环形队列
int front = 0; // 队首
int rear = -1; // 队尾初始化为-1

void enqueue(int value) {
    if (rear + 1 == front) {
        printf("Queue is full, can't enqueue.\n");
        return;
    }
    rear = (rear + 1) % MAX_PEOPLE; // 对于环形队列，索引加1后取模
    queue[rear] = value;
}

int dequeue() {
    if (front == rear) {
        printf("Queue is empty, can't dequeue.\n");
        return -1;
    }
    int value = queue[front];
    front = (front + 1) % MAX_PEOPLE; // 移动队首
    return value;
}

int main() {
    int people[90], i;
    
    for (i = 0; i < 90; ++i) {
        people[i] = i + 1;
    }

    for (i = 0; i < 90; ++i) {
        int current = people[i];

        if (current == 1) {
            int removed = dequeue();
            if (removed != -1)
                printf("%d was removed from the queue.\n", removed);
        } else {
            enqueue(current);
        }
    }

    return 0;
}

这段代码首先创建了一个环形队列，然后遍历给定的序列，根据报数规则进行入队和出队的操作。注意，队列满或空的情况需要特殊处理。运行这段程序，你可以看到每个人的出队顺序。
