FACTORIAL IN C++
#include <iostream>
using namespace std;
int main()
{
int i,fact=1,number;
cout<<"Enter any Number: ";
cin>>number;
for(i=1;i<=number;i++){
fact=fact*i;
}
cout<<"Factorial of " <<number<<" is: "<<fact<<endl;
return 0;
}c++ factorial
#include <cmath>
int fact(int n){
return std::tgamma(n + 1);
}
// for n = 5 -> 5 * 4 * 3 * 2 = 120
//tgamma performas factorial with n - 1 -> hence we use n + 1Copyright © 2021 Codeinu
