C语言实现队列的插入删除程序并调用生成_c语言删除程序

一、运行代码

#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>  
#define MAX_SIZE 10  
 
int queue[MAX_SIZE];
int front = -1, rear = -1;
 
void enqueue(int data) {
	if (rear >= MAX_SIZE - 1) {
		printf("队列已满，无法插入数据\n");
	}
	else {
		if (front == -1)
			front = 0;
		rear++;
		queue[rear] = data;
	}
}
 
int dequeue() {
	if (front == -1 || front > rear) {
		printf("队列为空，无法删除数据\n");
		return -1;
	}
	else {
		int data = queue[front];
		front++;
		return data;
	}
}
 
void display() {
	printf("当前队列中的元素为：\n");
	for (int i = front; i <= rear; i++) {
		printf("%d ", queue[i]);
	}
	printf("\n");
}
 
int main() {
	int n = 0;
	int flag = 1;//判断用户选择数是否合法
	while (flag)
	{
		printf("请输入队列的一到十内的目标长度\n");
		scanf("%d", &n);
		if (n >= 1 && n <= 10)
		{
			flag = 0;
		}
	}
	int dight = 0;
	for (int i = 0; i < n; i++)
	{
		printf("请输入第%d个元素的值：\n", i + 1);
		scanf("%d", &dight);
		enqueue(dight);
	}
	display();//显示刚刚压入的队列元素
 
	int  flags = 1;
	while (flags)
	{
		int choice = 1;
		int sth = 0;
		printf("-------------------------------------------------------\n");
		printf("请选择你想要的执行的操作：1.添加队列 2.删除队列 0.退出\n");
		printf("-------------------------------------------------------\n");
		scanf("%d", &choice);
		switch (choice)
		{
		case 1:
			printf("请输入待添加的元素：\n");
			scanf("%d", &sth);
			enqueue(sth);
			display();
			break;
		case 2:
			dequeue();
			display();
			break;
		case 0:
			flags = 0;
			break;
		default:
            printf("请输入有效值！\n");
			break;
		}
	}
	return 0;
}

二、运行结果
