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();
}
