求大佬，为什么这个十进制转化成八进制，八进制始终为0#include<stdio.h>#include<malloc.h>#define MaxSize 50typedef int ElemType;typedef struct{ ElemType data[MaxSize]; int top;}SqStack;void InitSqStack(SqStack * &s){ s=(SqStack * )malloc(sizeof(SqStack)); s->top=-1;}void DestroyStack(SqStack * &s){ free(s);}bool StackEmpty(SqStack * s){ return(s->top==-1); }bool Push(SqStack * &s,ElemType e){ if(s->top==MaxSize-1) s->top++; s->data[s->top]=e; return true; }bool Pop(SqStack * &s,ElemType &e){ if(s->top==-1) return false; e=s->data[s->top]; s->top--; return true;}bool GetTop(SqStack *s,ElemType &e){ if(s->top==-1) return false; e=s->data[s->top]; return true;}void DisStack(SqStack *s){ int e; while(true){ Pop(s,e); printf("%d",e); if(s->top==-1){ break; } }}int main(void){ SqStack *s; ElemType e; InitSqStack(s); int x; printf("请输入一个十进制的整数："); scanf("%d",&x); while(x>0){ Push(s,x%8); x=x/8; } printf("其八进制数为： "); DisStack(s); printf("\n"); }
