C :

#include<stdio.h>
int main()
{
    int x;
    scanf("%d",&x);
    if(x>=90)
        printf("Excellent");
if(x>=80&&x<90)
   
    printf("Good");
    if(x>=60&&x<80)
        printf("Pass");
    if(x<60)
        printf("Fail");
    return 0;
}

C++ :

#include<iostream>
#include<cstdio>
#include<cmath>
using namespace std;
int s;
int main()
{
	cin>>s;
	if(s==90||s>90)
	{
		cout<<"Excellent"; 
	}
	if(s==80||(s>80&&s<90))
	{
		cout<<"Good";
	}
	if(s==60||(s>60&&s<80))
	{
		cout<<"Pass";
	}
	if(s<60)
	{
		cout<<"Fail";
	}
	return 0;
}

Java :

import java.util.Scanner;

public class Main{
	public static void main(String[] args) {
		Scanner sc =new Scanner(System.in);
		int n =sc.nextInt();
		if(n>=90) {
			System.out.println("Excellent");
		}else if(n>=80&&n<90) {
			System.out.println("Good");
		}else if(n>=60&&n<80){
			System.out.println("Pass");
		}else {
			System.out.println("Fail");
		}
	}
}

Python :

n = int(input())
if 90 <= n <= 100:
    print('Excellent')
elif 80 <= n < 90:
    print('Good')
elif 60 <= n < 80:
    print('Pass')
elif 0 <= n < 60:
    print('Fail')
