Write a 'c' program using function to calculate the value of c(ncr)


Function to calculate the value of c(ncr) in C



c =     n!
                   ----------
                    r!*(n-r)!

#include<stdio.h>
#include<conio.h>

/*function prototype*/

int factorial(int);
void main( )
{
int n,r,c,factn,factr,factnr;

clrscr();

printf("\nEnter the value of n and r:");
scanf("%d%d",&n,&r);

/*calculate the factorial of n */

factn=factorial(n);

/*calculate the factorial of r */

factr=factorial(r);

/* calculate the factorail of n-r*/
factnr=factorial(n-r);

/*calculate the value of c */ 

c=factn/(factr*factnr);

printf("\nc=%d",c);

getch();
}
/*function definition */
int factorial(int num)
{
int fact=1,i;

for(i=1;i<=num;i++)
fact=fact*i;

return fact;
}

MVC Example 1

                        Swing MVC Example in java Java Swing first programs In this chapter, we will program our first programs in Swing toolkit. The examples are going  to be very simple. We will cover some basic functionality. Our first example In our first example, we will show a basic window. import javax.swing.JFrame; public class Simple extends JFrame { public Simple() { setSize(300, 200); setTitle("Simple"); setDefaultCloseOperation(EXIT_ON_CLOSE); } public static void main(String[] args) { Simple simple = new Simple(); simple.setVisible(true); } } While this code is very small, the application window can do quite a lot. It can be resized, maximized, minimized. All the complexity that comes with it has been hidden from the application programmer. import javax.swing.JFrame; Here we import the JFrame widget. It is a toplevel container, which is used for plac...
