[解决办法]
宏定义的后面不要加分号
另外，N%16入栈的时候，要注意区分0-9和A-F
[解决办法]
你要的是16进制的转换吧
C/C++
//数值转换
#include"stdio.h"
#include"stdlib.h"
#include"string.h"
#define ElemType int
#define STACK_INIT_SIZE 100
typedef struct
{
ElemType *base;
ElemType *top;
ElemType stacksize;
}SqStack;


void InitStack(SqStack *s)
{
s->base = (ElemType *)malloc(STACK_INIT_SIZE *sizeof(ElemType));
if (!s->base)
printf("分配内存失败\n");

s->top = s->base;
s->stacksize = STACK_INIT_SIZE;
}

int push(SqStack *s, int e)
{

if (s->top - s->base >= s->stacksize)
{
printf("栈满了\n");
}
else
{
*(s->top) = e;
s->top++;
}

return 0;
}

int StackEmpty(SqStack *s)
{
if (s->top > s->base)
return 1;
else
return 0;

}

int Pop(SqStack *s, int e)
{
if (s->top < s->base)
return 0;
else
{
s->top --;
e = *s->top;
switch(e)
{
case 10:printf("A");break;
case 11:printf("B");break;
case 12:printf("C");break;
case 13:printf("D");break;
case 14:printf("E");break;
case 15:printf("F");break;
default:printf("%d",e);break;
}
}
return 1;
}

int main()
{
int N,e;
SqStack s;
InitStack(&s);
scanf("%d",&N);
while (N)
{
int t =N%16;
push(&s,t);
N = N/16;

}
while(StackEmpty(&s))
{
Pop(&s,e);
}

return 0;
}
程序还是可以跑的，随便改改也可以变其他进制的了
