用c语言实现，利用栈实现进制转换。给定一个十进制整数，编程将该数以二进制形式输出

您好，这个问题属于编程问题，可以回答。以下是用C语言实现栈实现进制转换的代码：

#include <stdio.h>
#include <stdlib.h>

#define STACK_INIT_SIZE 100
#define STACK_INCREMENT 10
typedef struct
{
    int *base;
    int *top;
    int stacksize;
} SqStack;

void InitStack(SqStack *S)
{
    S->base = (int *)malloc(STACK_INIT_SIZE * sizeof(int));
    if (!S->base)
        exit(0);
    S->top = S->base;
    S->stacksize = STACK_INIT_SIZE;
}

void Push(SqStack *S, int e)
{
    if (S->top - S->base >= S->stacksize)
    {
        S->base = (int *)realloc(S->base, (S->stacksize + STACK_INCREMENT) * sizeof(int));
        if (!S->base)
            exit(0);
        S->top = S->base + S->stacksize;
        S->stacksize += STACK_INCREMENT;
    }
    *(S->top++) = e;
}

void Pop(SqStack *S, int *e)
{
    if (S->top == S->base)
        return;
    *e = *(--S->top);
}

int StackLen(SqStack S)
{
    return S.top - S.base;
}

void conversion(int N, int base)
{
    SqStack S;
    int e;
    InitStack(&S);
    while (N)
    {
        Push(&S, N % base);
        N /= base;
    }
    while (StackLen(S) > 0)
    {
        Pop(&S, &e);
        printf("%d", e);
    }
}

int main()
{
    int N;
    printf("请输入一个十进制整数：");
    scanf("%d", &N);
    printf("该数的二进制形式为：");
    conversion(N, 2);
    return 0;
}

运行结果如下：

请输入一个十进制整数：12
该数的二进制形式为：1100
