        //We will add the function.

        double price = Double.parseDouble(jTextField1.getText());
        double qty = Double.parseDouble(jTextField2.getText());             //double is used for values in points.
     
        double salAmt = price * qty;
        double disc = salAmt * 0.10;
        double netAmt = salAmt - disc;
     
        jTextField3.setText(" "+salAmt);
        jTextField4.setText(" "+disc);
        jTextField5.setText(" "+netAmt);        //Shortcut key used is SHIFT + DOWN ARROW.

C Program : Factorial Program using Recursion


#include<stdio.h>
long factorial(int n) {  
  
  if (n == 0)  
    return 1;  
  else  
    return(n * factorial(n-1));  
    }  
   
void main(){  
 
     int number;  
     long fact;  

     printf("Enter a number: ");  
     scanf("%d", &number);   
   
     fact = factorial(number);  
     printf("Factorial of %d is %ld\n", number, fact);  
 
     return 0;  
}  





Output:
Enter a number: 6
Factorial of 5 is: 720

C Program : Factorial Program using loop





#include<stdio.h>
int main(){
    
           int i,fact=1,number;    
           printf("Enter a number: ");    
           scanf("%d",&number); 
   
           for(i=1;i<=number;i++){    
                fact=fact*i;    
                }    
  
          printf("Factorial of %d is: %d",number,fact);    

          return 0;  
         }   


Output:
Enter a number: 5
Factorial of 5 is: 120
