function factorialOf(n){ var eq=n; for (;n>1;){ n--; eq *=n; } return eq; } sorry, written in JavaScript. But how ever the most important is the ALGORITHM. Language not very important, But without algorithm, CODING is NOTHING, also include math.

I did it in Java.Check this out.You can try in c++,logic will be same☺☺ package Java1; import java.util.*; public class Vool2 { public static void main(String[] args) { int N=1; Scanner input=new Scanner(System.in); System.out.println("Now enter a value to do factorial" ); int u=input.nextInt(); for(int i=u;i>0;i--) { N=i*N; } System.out.println(N); } }
