PHP数组函数实现栈与队列的方法介绍（代码示例）

typedef struct stack
{
	ElemType Data[MAXSIZE];
	int top;
}SqStack;
 

 
bool Push(SqStack *s,ElemType e)//压栈 
{
	if(s->top==MAXSIZE-1)
	    {
    	printf("Stack is Full\n");   	
		return FALSE;
	    }
	    s->Data[++(s->top)]=e;//先移指针再入数 
	    return TRUE;
}
bool  Pop(SqStack *s,ElemType *e)//出栈 
{
	if(s->top==-1)
	    {
    	printf("Stack is Empty\n");   	
		return FALSE;
	    }
		*e=s->Data[(s->top)--];//先取数再减指针 
		return TRUE;
}

 typedef struct queue
{
	ElemType Data[MAXSIZE];
	int front,rear;
}SqQueue;
 
 
bool EnQueue(SqQueue *q,ElemType e)//入队 
{
	if((q->rear+1)%MAXSIZE==q->front)  //队满 
	    {
    	printf("Queue is Full\n");   	
		return FALSE;
	    }
	    q->Data[q->rear]=e;
		q->rear=(q->rear+1)%MAXSIZE;//队尾指针加1取模 
		printf("EnQueue data %d into Queue \n",e);
	    return TRUE;
}
bool  DeQueue(SqQueue *q,ElemType *e)//出队 
{
	if(q->rear==q->front)
	    {
    	printf("Queue is Empty\n");   	
		return FALSE;
	    }
		*e=q->Data[q->front];//先取数再移指针 
		q->front=(q->front+1)%MAXSIZE;  //队头指针加1取模  
		printf("DeQueue data is %d\n",*e);
		return TRUE;
}
