factorial of a given number

Program that use non recursive function to find the factorial of a given integer.


Description:


Factorial of a number is nothing but the multiplication of numbers from a given number to 1 Ex: 5! =5*4*3*2*1= 120
#include<stdio.h>

#include<conio.h>

void main()

{

 long double fact=1;

 int i,n;

 clrscr();

 printf("enter any values\n");

 scanf("%d",&n);

 for(i=1;i<=n;i++)

 {

  fact=fact*i;

 }

 printf("%d!=%Lf\n",n,fact);

 getch();

}

Output:


1.Enter the number: 7
   Factorial of number is: 5040

2. Enter the number : 6
  Factorial of number is : 720

3. Enter the number: 8
 Factorial of number is: -25216

Conclusion:


The program is error free

VIVA QUESTIONS:

1)  What is meant by call by value ?
Ans: passing values to the function as arguments
 2) What is meant by call by reference ?

Ans: passing address to the function as arguments
 3)define actual parameters ?
Ans: The actual parameters often known as arguments are specified in the function call.
