只有40分，不知道哪里出问题了

#include<iostream>
using namespace std;
int main(){
   int a,b,c,d,e;
   cin>>a;
   if(a%2==0&&4<a&&a<=12)
     b=1;
	 else b=0;
  
   if(a%2==0||4<a&&a<=12||a%2==0&&4<a&&a<=12)
     c=1;
	 else c=0;
   if(a%2==0||4<a&&a<=12)
     d=1;
	 else d=0;
	if(a%2==0||4<a&&a<=12||a%2==0&&4<a&&a<=12)
	e=0;
	else e=1;
	 cout<<b<<" "<<c<<" "<<d<<" "<<e<<endl;
  return 0;
}
