十進制轉二進制

[~~~~~~氣質阿翔~~~~~~]

讓使用者輸入一整數n 然後印出2的n次方所有二進制的值

譬如n=3 就印出000 001 010 011 100 101 110 111

請問各位大大下面的程式碼哪裡有問題壓

我怎麼看都找不出問題在哪...

#include<iostream>
using namespace std;

int binary(int);
int main(){

int n,i,decimal=1;
cout<<"輸入一整數:";
cin>>n;
for(i=1;i<=n;i++){
decimal=decimal*2;
}
binary(decimal-1);
}

int binary(int num)
{
if(num>0)
{
int bin[10]={0},i,j,k,l,just[20]={0};
for(k=0;k<num;k++)
just[k]=num;
for(i=1;;i++)
{
bin[i]=num%2;
num=num/2;
if(num==0)
break;
}
for(j=i;j>0;j--)
{
cout<<bin[j];
}
for(l=0;;l++)
num=just[l];
return binary(num-1);
}
}
