Program to Calculate the Factorial Using Do While

Write a Program to calculate the factorial of entered no. using do while. Calculate the Factorial Using Do While

Algorithm:

  • Start
  • Enter a Number – A
  • do
    {
    fact=fact*i;
    i++;
    }
    while(i<=n);
  • Print Factorial=fact(a)
  • Stop

Source Code

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