Pentatope number

Given a number n, the task is to write a program to find Nth pentatope number. A pentatope number is class of figurative number and can be represented as regular and discrete geometric patterns. In pascal triangle’s the number in the fifth cell of any row starting with 5-th term row 1 4 6 4 1 from right to left or left to right is Pentatope number.
Examples :

Input : 5 
Output :70
Input :8 
Output :1001 

First few Pentatope numbers are: 
1, 5, 15, 35, 70, 126, 210, 330, 495, 715, 1001………
Formula for Nth Pentatope number: 

C++

// C++ Program to find the
// nth Pentatope Number
#include <bits/stdc++.h>
using namespace std;

// Function that returns nth
// pentatope number
int pentatopeNum(int n)
{
    return (n * (n + 1) * (n + 2) * (n + 3)) / 24;
}

// Drivers Code
int main()
{
    // For 5th PentaTope Number
    int n = 5;
    cout << pentatopeNum(n) << endl;

    // For 11th PentaTope Number
    n = 11;
    cout << pentatopeNum(n) << endl;

    return 0;
}

C

// C Program to find the
// nth Pentatope Number
#include <stdio.h>

// Function that returns nth
// pentatope number
int pentatopeNum(int n)
{
    return (n * (n + 1) * (n + 2) * (n + 3)) / 24;
}

// Drivers Code
int main()
{

    // For 5th PentaTope Number
    int n = 5;
    printf("%d\n",pentatopeNum(n));

    // For 11th PentaTope Number
    n = 11;
    printf("%d\n",pentatopeNum(n));

    return 0;
}
