Write a Program to Calculate the Factorial of Entered no. Using for Loop.  Calculate the Factorial Using For Loop

Algorithm

• Step 1: Start
  Step 2: Enter a number-a
  Step 3:      for(i=1;i<=n;i++)
•                {
•                f=f*i;
•                }
  Step 4: print Factorial=fact(a)
  Step 5: Stop
• Source Code

#include<iostream.h>
#include<conio.h>
void main(){
 int n, i, f=1;
 clrscr();
 cout<<"Enter a number: ";
 cin>>n;
               for(i=1;i<=n;i++)
               {
               f=f*i;
               }
 cout<<endl<<"the factorial is: "<<f;
 getch();
}
