Factorial Example

            #include<stdio.h>
            #include<conio.h>
        
            void factorial(int no)
            {
                int k, f;
                f = 1;
        
                for (k = 1; k <= no; k++)
                {
                    f = f * k;
                }
        
                printf("\n Factorial of %d is %d", no, f);
            }
        
            int main()
            {
                clrscr();
        
                factorial(3);
                factorial(4);
        
                getch();
