C :

#include<stdio.h>

 

int main()

{

   int high=0,mid=0,low=0;

   int x;

   while(scanf("%d",&x), x>0)

   {

      if(x >= 85)

         high++;

      else if(x >= 60)

         mid++;

      else

         low++;

   }

   printf(">=85:%d\n60-84:%d\n<60:%d\n",high,mid,low);

 

   return 0;

}

C++ :

#include<iostream>
using namespace std;
int main()
{
	int x,a=0,b=0,c=0;
	while (cin>>x && x>0)
		if (x>=85) a++;
		else if(x>=60) b++;
		else c++;
	cout<<">=85:"<<a<<endl;
	cout<<"60-84:"<<b<<endl;
	cout<<"<60:"<<c<<endl;
	return 0;
}
