Write a Program in C To find Factorial of a given number

Objective : Write a Program in C To find Factorial of a given number

The factorial of a integer n, denoted by n!, is the product of all positive integers less than or equal to n. For example,

Factorial of 5 = 5! = 5 X 4 X 3 X 2 X 1 = 120

The value of 0! is 1, according to the convention for an empty product.

So, given below is Program in C To find Factorial of a given number.

PROGRAM CODE :

#include<stdio.h>

#include<conio.h>

void main()

{

   int k,n,fact = 1;

   clrscr();

printf("----->FACTORIAL<-----\n");

   printf("Enter a number: ");

   scanf("%d",&n);

   for(k=1;k<=n;k++)

   fact=fact*k;

   printf("\nFactorial of %d = %d \n",n,fact);

   getch();

}
