Question

C++ PROBLEM:

Create a program that calculates the hyperfactorial of any positive integer n, where the hyperfactorial is equivalent to value obtained by the operation: 1^1*2^2*3^3*…..n^n . If user inputs the value that is not a positive value, display a message informing the user that the input is not valid and request a new input. Calculate the hyperfactorial first by creating a program that uses only nested “For loop” structure.

Answer 1

C++ code:

#include<iostream>

using namespace std;

int main(){

// Declarig a varibale to store hyperfactorial

long long int hf = 1;

// Asking the user to enter n

int n;

cout << "Enter n: ";

cin >> n;

// Checking for condition

while(n <= 0){

cout << "n should be > 0" << endl;

cout << "Enter n: ";

cin >> n;

}

// Running nested for loop to calculate hf

for(int i = 1; i <= n; ++i){

for(int j = 1; j <= i; ++j){

hf *= i;

}

}

// Displaying the hyperfactorial

cout << "Hyperfactorial of a number is " << hf << endl;

return 0;

}
