C++ :

#include<iostream>
#include<cstdio>
#include<cmath>
using namespace std;
int main()
{
	float score;
	cin>>score;
	if(score>=90)cout<<"outstanding"<<endl;
	if((score<90)&&(score>=60))cout<<"satisfactory"<<endl;
	if(score<60)cout<<"unsatisfactory"<<endl;
	return 0;	
}

Python :

# coding=utf-8
score = float(input())

if score >= 90:
    print("outstanding")
elif score >= 60:
    print("satisfactory")
else:
    print("unsatisfactory")
