kiki有一个十进制数，他想转成r进制，请你编程帮他实现。C语言

以下是C语言实现将十进制数转换为r进制的代码：

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

#define STACK_INIT_SIZE 100
#define STACKINCREMENT 10

typedef struct {
    int *base;
    int *top;
    int stacksize;
} SqStack;

SqStack *Init_seqstack() {
    SqStack *s = (SqStack *) malloc(sizeof(SqStack));
    s->base = (int *) malloc(STACK_INIT_SIZE * sizeof(int));
    if (!s->base) {
        exit(0);
    }
    s->top = s->base;
    s->stacksize = STACK_INIT_SIZE;
    return s;
}

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

int Pop_seqstack(SqStack *s) {
    int e;
    if (s->top == s->base) {
        return -1;
    }
    s->top--;
    e = *(s->top);
    return e;
}

void Conversion(int num, int r) {
    SqStack *s = Init_seqstack();
    int sum = 0;
    while (num) {
        sum = num % r;
        Push_seqstack(s, sum);
        num = num / r;
    }
    while (s->top != s->base) {
        int e = Pop_seqstack(s);
        if (e >= 10) {
            printf("%c ", e + 55);
        } else {
            printf("%d ", e);
        }
    }
    printf("\n");
}

int main() {
    int num, r;
    scanf("%d%d", &num, &r);
    Conversion(num, r);
    return 0;
}
