栈的操作进栈次序问题

 设计一个栈，元素进栈的次序为A,B,C,D,E,请写出得到如下序列的操作序列：C,B,A,D,E.

A，B，C进，然后C，B，A出，再D进D出，再E进E出
你是需要写一个栈吗？那后main里写进栈出栈？

#include<stdio.h>
#include<malloc.h>

//定义栈 
typedef struct{
    char data[100];
    int top;
    int bottom;
}stack;

//创建栈
stack *StackCreate(){
    stack *p=(stack*)malloc(sizeof(stack));//分配新空间 
    if(p==NULL)//分配失败 
    return 0;
    p->bottom=p->top=0;//分配成功 
    return p;
}

//入栈
void StackInput(stack *p,char str){
    p->data[p->top]=str;//存入栈中 
    p->top++;//栈顶指针加1 
} 

//出栈 
char StackOutput(stack *p){
    char str;
    if(p->top!=p->bottom){//栈非空 
        str=p->data[p->top-1];//栈顶内容输出 
        p->top--;//栈顶减1 
        return str;
    }
} 

//输出 
void StackPrint(stack *p){
    while(p->top!=p->bottom){
        printf("%c",p->data[p->top-1]);
        p->top--;
    }
}

//主函数 
int main(){
    int i;
    stack *p=StackCreate();//创建栈      
    StackInput(p,'A');
    StackInput(p,'B');
    StackInput(p,'C');
    printf("%c",StackOutput(p));
    printf("%c",StackOutput(p));
    printf("%c",StackOutput(p));
    StackInput(p,'D');
    printf("%c",StackOutput(p));
    StackInput(p,'E');
    printf("%c",StackOutput(p));
}

解答如下，有问题请回复，有帮助请采纳
