C :

#include <stdio.h>
#include <stdlib.h>
 
int main()
{
    int appleh[10], benchh, taoh, bentaoh, i;
    benchh = 30;   
    for (i=0; i<10; i++)   
    {
        scanf("%d", &appleh[i]);
    }
    scanf("%d", &taoh);     
    bentaoh = benchh + taoh;   
    int n = 0;
    for (i=0; i<10; i++)
    {
        if(appleh[i] <= bentaoh)
        {
            n++;  
        }
    }
    printf("%d\n", n);
    return 0;
}

C++ :

#include<iostream>
#include<cstdio>
using namespace std;
int main()
{
	int a,b;
	int ge=0;
    int c[10];
    for(int i=1;i<=10;i++)
        cin>>c[i];
    cin>>b;
    b+=30;
    for(int i=1;i<=10;i++)
       if(c[i]<=b)
         ge++;
    cout<<ge;
        	
        
}

Pascal :

var
  i,s,n:longint;
  a:array [1..200] of longint;
begin
  //assign(input,'apple.in');
  //assign(output,'apple.out');
 // reset(input);
 // rewrite(output);
  for i:=1 to 10 do
    read(a[i]);
  s:=0;
  read(n);
  n:=n+30;
  for i:=1 to 10 do
    if a[i]<=n then
    s:=s+1;
  writeln(s);
 // close(input);
 // close(output);
end.

Java :

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int[] a = new int[10];
		int b = 30;
		int sum = 0;
		for(int i=0;i<10;i++) {
			a[i] = sc.nextInt();
		}
		int n = sc.nextInt();
		for(int i=0;i<10;i++) {
			if(n>=a[i]) {
				sum++;
			}else if(n+b>=a[i]) {
				sum++;
			}
		}
		System.out.println(sum);
		sc.close();
	}
