i think I might use a do..while loop here so when the number equals to 1 the loop must stop since the factorial of any number is (n*n-1)

Using Recursion: #include <iostream> using namespace std; int fact(int n){ if(n==2) return 2; else return(n*fact(n-1)); } int main() { int n; cin>>n; cout<<"factorial is "<<fact(n); return 0; }
