Show Content Dynamically Using Javascript

Hi friends, today i will tell you how to show content dynamically using Javascript.

Here i am creating a drop down that contains 3 options when user click on any option than corresponding content will display to you.

Code :

<!DOCTYPE html>
<html>
<head>
<title>
Drop Down With Javascript
</title>
<style>
h1
{
display:none;
}
</style>
<script>
function liveShow()
{
var value=document.getElementById('city').value;
if(value=="Chennai")
{
document.getElementById("chennai").style.display="block";
document.getElementById("bangalore").style.display="none";
document.getElementById("delhi").style.display="none";
}

C Program That Count Odd Number In Fibonacci Series

Hello friends today i am sharing a simple program that will count odd numbers with in Fibonacci series.But before that you have know about fibonacci series,so let me explain.

What is Fibonacci Series ?
The Fibonacci series is a set of numbers that starts with a one or a zero, followed by a one, and proceeds based on the rule that each number (called a Fibonacci number) is equal to the sum of the preceding two numbers.
In mathematical terms,the sequence F(n) of Fibonacci number is defined by following recurrence relation.
F(n)=F(n-1) + F(n-2)
with
F(1)=1 ,F(2)=1
Or
F(0)=0,F(1)=1

For example:-

1,1,2,3,5,8,13,21,34,........
or
0,1,1,2,3,5,8,13,21,34,.........

So if you enter 8, then till 8 we have 4 odd numbers(1,1,3,5).Similarly if you enter 34,then till 34 we have 6 odd numbers(1,1,3,5,13,21).

Now try to understand this code,I am sure you can easily understand this code..:) :)

Code :-

#include<stdio.h>

#include<conio.h>

int main(){

int num,a=0,b=1,c,count=1;

printf("\n\n\n\n WAP to count odd numbers in fibonacci series");

printf("\n Enter the number:");

scanf("%d",&num);

while(1)

{

c=a+b;

while(n!=0)
{
     j=n;
   while(j!=0)

   }
       }
if(len==4)
  printf(" thousand ");
else if(len==3)
  printf(" hundred ");
else if(len==2)
{
  if(n==11)

  else if(n>=90&&n<100)
   printf(" ninty ");
}
if(len==4)
  n=n-(rem*1000);
else if(len==3)
  n=n-(rem*100);
else if(len==2)
  n=n-(rem*10);
else if(len==1)
  n=n-rem;

What Is ASCII?

Hello friends,ASCII(American Standard Code for Information Interexchange) is an industry standard, which assigns letters, numbers, and other characters within the 256 slots available in the 8-bit code.

The ASCII table is divided in 3 sections:

Non printable: This table contain system codes between 0 and 31.

Lower ASCII: This table is generated from older American Standard with work on 7 bit code and contain characters between 32 and 127..

Higher ASCII: This portion is programmable, Foreign letters are also placed in this section.This table contain characters between 128 and 255.

******Thanks friends******

What Is Associative Operation?

Hello friends,in programming, an associative operation occurs when no grouping is present, where operators that have the same precedence (addition and subtraction) will be evaluated either from left to right (left-associative) or from right to left (right-associative).

For example:If no grouping(parentheses) is present than 4-3+1 give the result 2 because here we start calculation from left but if grouping is present ie 4-(3+1) then result is 0 because we first calculate (3+1).

In most programming languages, the addition, subtraction, multiplication, and division operators are left-associative, while the assignment, conditional, and exponentiation operators are right associative.

What Is Applet?

Friends, Applet is a small program that does a job a larger program is incapable of doing. For instance,a Sun Java applet is a file on an Internet web page that provides additional functionality not supported by HTML.

Thanks Friends.......

What is API?

Hello friends how are you ?I know that you all are pretty well.Today i am sharing some important details about API,i hope you really enjoying it.

API(Application Program Interface) is a set of routines, protocols, and tools for building software applications. APIs allow programmers easier entry into another companies program or service. For example, large companies and communities such as Facebook and Twitter have APIs that allow programmers or website developers easier access to their services and members.
