棧的C數組實現,C數組實現
棧是一種先進後出的資料結構.
棧的基本操作包括:入棧,出棧,初始化棧,清空棧,遍曆棧.
C代碼如下:
#include <stdio.h>#define MaxSize 20typedef int ElemType;typedef struct stack{ ElemType Data[MaxSize]; int top;}Stack;//初始化棧void InitStack(Stack *S){ S->top=-1;}//入棧void PushStackValue(Stack *S){ printf("Input the Value of stack member:\n(0-exit)\n"); int value; printf("Please input the 1st value of stack:\n"); scanf("%d",&value); S->Data[++S->top]=value; while(value) { S->top++; printf("Please input the %dst value of stack:\n",S->top+1); scanf("%d",&value); S->Data[S->top]=value; }}//出棧void PopStackValue(Stack *S){ if(S->top>=0) { printf("the stack %dst value pop out: %d\n",S->top+1,S->Data[--S->top]); } else { printf("The Stack is empty\n"); }}//判斷棧空void IsEmpty(Stack *S){ if(S->top==-1) { printf("The Stack is empty.\n"); } else { printf("The stack is not empty.\n"); }}//清空棧void ClearStack(Stack *S){ S->top=-1;}//遍曆棧void ScanStack(Stack *S){ int i; int len=S->top-1; int StackArray[len]; for(i=len;i>0;i--) { StackArray[i]=S->Data[i--]; } printf("The all stack member(from top to bottom) is:\n"); while(len>=0) { printf("%d ",S->Data[len--]); } printf("\n");}void main(){ Stack S; InitStack(&S); PushStackValue(&S); ScanStack(&S); IsEmpty(&S); PopStackValue(&S); PopStackValue(&S); PopStackValue(&S); PopStackValue(&S);}
運行結果如下:

用數組實現棧與隊列的資料結構
#include <stdlib.h>
#include <stdio.h>
class Stack
{
private:
int ele[100];
int top;
public:
Stack() {
top = 0;
}
void push(int v) {
ele[top++] = v;
}
int pop() {
if(isEmpty()) {
printf("The stack is Empty.\n");
return -1;
}
return ele[--top];
}
bool isEmpty() {
return top == 0;
}
~Stack() {
}
};
#define SIZE 100
class Queue
{
private:
int ele[SIZE];
int head;
int tail;
public:
Queue() {
head = 0;
tail = 0;
}
bool isFull() {
return (tail+1) % SIZE == head;
}
bool isEmpty() {
return head == tail;
}
void enqueue(int val) {
if(isFull()) {
printf("The queue is full, can not enqueue for: %d\n", val);
return;
}
ele[tail] = val;
tail = (tail+1) %SIZE;
}
int dequeue() {
if(isEmpty()) {
printf("The queue is empty, can not dequeue.\n");
return -1;
}
int value = ele[head];
head = (head+1)%SIZE;
return value;
}
};
int main()
{
Stack s;
s.push(123);
s.push(12);
while(!s.isEmpty()) {
printf("%d ", s.pop());
}
printf("\n");
Queue q;
q.enqueue(88);
q.enqueue(13);
q.enqueue(123);
while(!q.isEmpty()) printf("%d ", q.dequeue());
printf("\n");
system("pause");

用數組實現棧的功可以的C語言代碼?
棧在處理數組上面真的很方便,這是棧的基礎方法函數
//順序棧的實現stack.cpp
#include "stack.h"
Status SqStack::InitStack(SqStack **S)
{ (*S)=(SqStack *) malloc(sizeof(SqStack));
(*S)->base=(SElemType *)malloc(STACKSIZE *sizeof(SElemType));
if(!(*S)->base) exit(OVERFLOW);
(*S)->top=(*S)->base;
(*S)->stacksize=0;
return 1;}
Status SqStack::DestroyStack()
{free(base);return 1;}
Status SqStack::ClearStack()
{stacksize=0;return 1;}
bool SqStack::StackEmpty()
{ if(stacksize==0) return true;
else return false;
}
int SqStack::StackLength()
{ return stacksize;}
SElemType SqStack::GetTop()
{ if(top==base)
{cerr<<"空棧!\n";exit(1);}
return *(top-1);
}
Status SqStack::Push(SElemType e)
{ *(top++)=e;stacksize++;
return 1;
}
SElemType SqStack::Pop(SElemType *e)
{ if(top==base)
{cerr<<"空棧!\n";exit(1);}
*e=*--top;
stacksize--;
return *e;
}
void SqStack::StackTraverse(void (*visit)(SElemType *))
{while(top!=base){
stacksize--;visit(--top);}}
