Introduction
I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.
Write C++ program to find factorial of a number using recursion
#include <iostream>
using namespace std;
// Function declaration
unsigned long long Findfact(int num);
int main()
{
int num;
unsigned long long factorial;
// Inputting an integer from user
cout<<"Enter any number: ";
cin>>num;
factorial = Findfact(num);
cout<<"Factorial of " <<num<< " is "<<factorial;
return 0;
}
unsigned long long Findfact(int num)
{
// Base condition
if(num == 0)
return 1;
else
return num * Findfact(num - 1);
}
Result
