一、函数实现

1、ClearSqStack

（1）用途

清理栈的空间。只需要栈顶指针和栈底指针相等，就说明栈已经清空，后续新入栈的数据可以直接覆盖，不用实际清理数据，提升了清理效率。

（2）源码

Status ClearSqStack(SqStack* S)
{JudgeAllNullPointer(S);S->TopPointer = S->BasePointer;Log("Clear SqStack   : OK\n",Info);return SuccessFlag;
}

（3）参数

2、DestroyStack

（1）说明

销毁栈。释放申请的资源。

（2）源码

Status DestroyStack(SqStack* S)
{JudgeAllNullPointer(S);free(S->BasePointer);S->TopPointer     = NULL;S->BasePointer    = NULL;S->SqStackMaxSize = 0;Log("Destroy SqStack : OK\n",Info);return SuccessFlag;
}

（3）参数

3、PushSqStack

（1）说明

压栈。判断栈是否已满，如果已满报错，反之将数据压入栈顶即可。

（2）源码

Status PushSqStack(SqStack* S, SqElemType SE)
{JudgeAllNullPointer(S);//判断是否栈满if(GetSqStackLen(S) >= S->SqStackMaxSize){Log("SqStack is Full, Data cannot be pushed\n",Warning);return FailFlag;}//相同结构体之间，可以直接赋值。*(S->TopPointer) = SE;//CopySqElemType(S->TopPointer, &SE);//printf("%p, %p\n",S->TopPointer->StudentNum, (&SE)->StudentNum);S->TopPointer++;Log("Push SqStack    : OK\n",Info);return SuccessFlag;
}

（3）参数

4、PopSqStack

（1）说明

弹栈。判断栈是否已空，如果是，就抛出错误。如果不是，就下移栈顶指针，将数据赋值给SE，作为传出参数。

（2）源码

Status PopSqStack(SqStack* S, SqElemType* SE)
{JudgeAllNullPointer(S);JudgeAllNullPointer(SE);if(JudgeSqStackIsEmpty(S) == SuccessFlag){Log("SqStack is Empty, Data cannot be poped\n",Warning);return FailFlag;}S->TopPointer--;*SE = *(S->TopPointer);//CopySqElemType(SE,S->TopPointer);//printf("%p, %p\n",S->TopPointer->StudentNum, SE->StudentNum);Log("Pop SqStack     : OK\n",Info);return SuccessFlag;
}

（3）参数

二、虚机测试

gcc -Wall -O3 Log.c SqStack.c main.c -o TestSqStack[gbase@czg2 LinearTable_Stack]$ ./TestSqStack
