void main()
{
int n,i,factorial=1; //if we want to find the factorial of a large number we can declare the factorial variable datatype as 'unsigned long long'
printf(“Enter the number :”);
scanf(“%d”,&n);
for(i=0;i<=n;i++)
{
factorial=factorial*i; //compute factorial
}
printf(“The factorial of the number is %d”,factorial);
getch();
}
