C语言简单实现入栈出栈

博主由于某种原因很久没写代码了,所以今天简简单单用C语言写了个入栈出栈的代码。

#include <stdio.h>

#define Elemytype int
#define Maxsize 50
#define True 1
#define Flase 0

typedef struct Seq_stack{
    Elemytype data[Maxsize];
    Elemytype Top;
}Seq_stack;

Elemytype Push_stack(Seq_stack *Stack,Elemytype num);
Elemytype Pop_stack(Seq_stack *Stack,int *num);

int main(void)
{
    Seq_stack Stack;
    Stack.Top = 0;
    int num = 0;
    printf("%d",Push_stack(&Stack,num));
    num = 1;
    printf("%d",Pop_stack(&Stack,&num));
    printf("%d",num);
    return 0;
}

Elemytype Push_stack(Seq_stack *Stack,Elemytype num)
{
    if (Stack -> Top >= Maxsize - 1)
    {
        printf("%s","*");
        return Flase;
    }
    Stack -> data[++(Stack -> Top)] = num;
    return True;
}

Elemytype Pop_stack(Seq_stack *Stack,int *num)
{
    if(Stack -> Top == -1)
    {
        printf("%s","Stack Empty");
        return Flase;
    }
    *(num) = Stack -> data[(Stack -> Top)--];
    return True;
}

Elemytype Get_top(Seq_stack *stack,int *num)
{
    if(Stack -> Top == -1)
    {
        printf("%s","Stack Empty");
        return Flase;
    }
    *num = stack -> data[stack -> Top];
    return True;
}
