C++，简单循环队列的实现

#include
#define MAXQSIZE 100
#define OK 1
#define ERROR 0
#define OVERFLOW -1

typedef int QElemType;
typedef int Status;
using namespace std;
typedef struct{
	QElemType *base;
	int front;
	int rear;
}SqQueue;

//循环队列的初始化 
Status InitQueue(SqQueue &Q){
	Q.base=new QElemType[MAXQSIZE];
	if(!Q.base) exit(OVERFLOW);
	Q.front=Q.rear=0;
	return OK;
} 

//入队
Status EnQueue(SqQueue &Q,QElemType e){
	if((Q.rear+1)%MAXQSIZE==Q.front)
		return ERROR;
	Q.base[Q.rear]=e;
	Q.rear=(Q.rear+1)%MAXQSIZE;
	return OK;	
} 

//打印队列元素 
Status printQueue(SqQueue Q){
	QElemType e;
	while(Q.front!=Q.rear){
		e=Q.base[Q.front];
		cout<>n;
	cout<<"请输入队列中的各个元素："<>e;
		EnQueue(Q,e);
	} 
	cout<<"此时队列中有"<<(Q.rear-Q.front+MAXQSIZE)%MAXQSIZE<<"个数据元素,如下所示："<>x;
	EnQueue(Q,x);
	cout<<"此时队列中有"<<(Q.rear-Q.front+MAXQSIZE)%MAXQSIZE<<"个数据元素,如下所示："<
