编程问题

用c语言，设计函数，实现十进制到二进制的转换，

Answer 1

#include "conio.h"
#include "stdio.h"
void fun(int m,int k)
{
int aa[20],i;
for(i=0;m;i++)
{
aa[i]=m%k;
m/=k;
}
for(;i;i--)
printf("%d",aa[i-1]);
}
main()
{
int b=2,n;
printf("\nPlease enter a number :\n");
scanf("%d",&n);
fun(n,2);
printf("\n");
}

Answer 2

#include <stdio.h>
int binary(int n);
int main()
{int num;
printf("Input Dec Number:");
scanf("%d",&num);
if(num>=0) {
binary(num);
printf("\n-------------------\n");
}

return 0;}
int binary(int n)
{if(n) binary(n/2);
else return 0;
printf("%d",n%2);
}
