Solution in C# (judge verdict: Accepted)

using System;
using System.Linq;

class Program
{
    public static void Main()
    {
        int[] data = Console.ReadLine().Split().Select(int.Parse).ToArray();
        int count = 0;
        
        for(int i = data[0]; i <= data[1];i++)
        {
            if(data[2] % i == 0)count++;
        }
        
        Console.WriteLine(count);
    }
