Program to Calculate the Factorial Using While

Write a Program to Calculate the Factorial of Entered No. Using While
Algorithm
- Start
- Enter a number-a
- e(n!=0)
{
f=f*n;
n–;
} - Print Factorial=fact(a)
- Stop
Source Code
#include<iostream.h> #include<conio.h> void main(){ int n, i, f=1; clrscr(); cout<<"Enter a number: "; cin>>n; while(n!=0) { f=f*n; n--; } cout<<endl<<"the factorial is: "<<f; getch(); }
