C :

#include<stdio.h>

void main() {
	int a[100];
	int n,i,c=0;
	scanf("%d",&n);

	for(i=0;i<n;i++){
		scanf("%d",&a[i]);
		if(a[i]>=90){
			c++;
		}
	}

	printf("%d\n",c);
}

C++ :

#include <iostream>
using namespace std;

int main(){
    int a[100],i,n,c = 0;
    cin>>n;
    for(i = 0;i < n;i++){
    	cin>>a[i];
    	if(a[i] >= 90){
    		c++;
		}
	}
	
	cout<<c<<endl;
}

Pascal :

var a:array[1..100000] of longint;
    i,b,s:longint;
begin
read(b);
for i:=1 to b do
read(a[i]);
for i:=1 to b do
if a[i]>=90 then inc(s);
write(s);
end.

Java :

import java.util.Scanner;
public class Main{

	public static void main(String[] args) {
    Scanner sc=new Scanner(System.in);
    int n=sc.nextInt(),i,s=0;
    int[] a=new int[n];
    for( i=0;i<n;i++) {
    	a[i]=sc.nextInt();
    }
    for( i=0;i<n;i++) {
    	if(a[i]>=90) {
    		s++;
    	}
    }
    System.out.print(s);
    sc.close();
	}

}

Python :

n = int(input())
s = input().split()
c = 0
for i in range(0, len(s)):
    if int(s[i]) >= 90:
        c += 1
print(c)
