求助 大佬帮忙看看这个程序哪里出错了
对着视频找了很久也找不到#include <stdio.h>
#include<stdlib.h>
#include<math.h>
#define STACK_INIT_SIZE 20
#define STACKINCREMENT10
typedef char ElemType;
typedef struct
{
ElemType *base;
ElemType *top;
int stackSize;//栈容量
}sqStack;
void InitStack(sqStack *s)
{
s->base = (ElemType *)malloc(STACK_INIT_SIZE * sizeof(ElemType));
if( !s->base )
{
exit(0);
}
s->top = s->base;
s->stackSize = STACK_INIT_SIZE;
}//以上全是栈初始化的过程
void Push( sqStack *s, ElemType e)
{
if( s->top - s->base >= s->stackSize )
{
s->base = (ElemType *)realloc(s->base, (s->stackSize + STACKINCREMENT) * sizeof(ElemType));
if( !s->base )
{
exit(0);
}
*(s->top) = e;
s->top++;
}//以上全是压栈操作
}
void Pop(sqStack *s, ElemType *e)
{
if(s->top == s->base)
{
return;
}
*e =*--(s->top);
}//以上是弹栈操作
int StackLen(sqStack s)
{
return (s.top - s.base );//将地址指向的元素相-
}
int main()
{
ElemType c;
sqStack s;
int len, i ,sum = 0;
InitStack(&s); //初始化栈
printf("请输入二进制数，输入#符号并表示结束 \n");
scanf("%c", &c);
while(c != '#')
{
Push(&s, c);
scanf("%c", &c);
}
getchar(); //吧'\n' 从缓冲区去掉
len = StackLen(s);
printf("栈的当前容量是 : %d\n", len);
for(i = 0; i < len; i++)
{
Pop(&s, &c);
sum = sum + (c-48) * pow(2, i);//二的i次方
}
printf("转化为十进制数是： %d\n", sum);
return 0;
}
运行的话 当前容量和转化为十进制数全是0 不知道哪里出错了 void Push( sqStack *s, ElemType e)
{
if( s->top - s->base >= s->stackSize )
{
s->base = (ElemType *)realloc(s->base, (s->stackSize + STACKINCREMENT) * sizeof(ElemType));
if( !s->base )
{
exit(0);
}
}//★★★★★ 括号该在这儿，逻辑才合理{:10_266:}
*(s->top) = e;
s->top++;
}//★★★★★ 括号放错地了
}
