32. WRITE A C PROGRAM TO CALCULATE FACTORIAL VALUE USING DO WHILE

/* calculate factorial value using do while */

#include<stdio.h>
#include<conio.h>
void main()
{
long int i,n,fact=1; /*variable declaration */
clrscr();
printf("Enter the value of n \n");
scanf("%ld", &n);
/* do loop start */
i=1;
do
{
fact*=i;
i++;
}
while(i<=n);

printf("Factorial = %ld\n",fact);
getch();
}

output

enter the value of n
6
factorial = 720
