写完了。但是这4个错误都找不出来

s->top++;

if (s->top == s->base){

int main(){

int len, i, sum = 0;
Initstack (&s);
printf("请输入二进制数,输入#表示结束! \n");
scanf("%c", &c);
while(c != '#'){
Push(&s, c);
scanf("%c", &c);
}
getchar ();//把\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);
}
printf("转换为十进制是:%d\n", sum);
return 0;
} 第8行“()”去掉;
pop函数改为:
void pop(sqStack *s, ElemTyppe *e)
保证定义的函数和调用的函数字母大小写一致
