This function can also be used to check if a character is a consonant
 or not, 
If it's not a vowel then it will be a consonant, but make sure 
that the character is an alphabet not a special character.

 In c language when we divide two integers we get integer result for 
example 5/2 evaluates to 2. As a general rule integer/integer = integer 
and float/integer = float or integer/float = float. So we convert 
denominator to float in our program, you may also write float in 
numerator. This explicit conversion is known as typecasting.</div>

c program to check odd or even

<div dir="ltr" style="text-align: left;" trbidi="on">
c program to check odd or even: We will determine whether a number is 
odd or even by using different methods all are provided with a code in c
 language. As you have study in mathematics that in decimal number 
system even numbers are divisible by 2 while odd are not so we may use 
modulus operator(%) which returns remainder, For example 4%3 gives 1 ( 
remainder when four is divided by three). Even numbers are of the form 
2*p and odd are of the form (2*p+1) where p is is an integer.

 printf("Enter an integer\n");
 scanf("%d",&n);
 
 if ( n%2 == 0 )
 printf("Even\n");
 else
 printf("Odd\n");
 
 return 0;
}</pre>
</div>
We can use bitwise AND (&) operator to check odd or even, as an 
example consider binary of 7 (0111) when we perform 7 & 1 the 
result will be one and you may observe that the least significant bit of
 every odd number is 1, so ( odd_number & 1 ) will be one always 
and also ( even_number & 1 ) is zero.

In c programming language when we divide two integers we get an 
integer result, For example the result of 7/3 will be 2.So we can take 
advantage of this and may use it to find whether the number is odd or 
even. Consider an integer n we can first divide by 2 and then multiply 
it by 2 if the result is the original number then the number is even 
otherwise the number is odd. For example 11/2 = 5, 5*2 = 10 ( which is 
not equal to eleven), now consider 12/2 = 6 and 6 *2 = 12 ( same as 
original number). These are some logic which may help you in finding if a
 number is odd or not.

WhatsApp recently introduce the blue tick button to notify that your 
message has been read or not but unfortunately this one reamin unpopulat
 between its users. Do you want to make disable this feature? don't 
worry i 'll tell you how you can do this.
This is just an optional feature you just can disable it by going 
setting-> Privacy and read reception option.
Those who download WhatsApp newer version can disable it directly from 
read reception option but this is only available for android users.This 
feature is like last seen option but this one can be disable easily.
but if someone off this feature not the sender neither the receiver 
gonna see this option means one side action can effect both the parties.

New Delhi: 
 A wishlist sent out to ministries by the Prime 
Minister's Office on celebrating "good governance day" on December 25 
suggests it could be a working Christmas for many in the government. 
Sources said a detailed plan and directive from the government could 
follow. It is former Prime Minister Atal Bihari Vajpayee's 90th
 birthday on Thursday and Prime Minister Narendra Modi had announced 
that it would be observed as "good governance day." The PMO note
 suggests that ministers and MPs should visit "sensitive districts and 
organise events on good governance and sanitation on December 25" and 
also organise other events. It has also suggested holding seminars with eminent speakers, e-governance camps and promoting digital literacy on that day. A
 detailed circular from the Department of Personnel and Training is 
expected soon, which is likely to calendar Thursday's activities for 
ministers and government employees on Christmas Day-  a gazetted 
holiday.  
 
There has already been controversy over an Education Ministry circular 
on students' participation in activities for good governance day, but 
the government has clarified that schools will be closed for Christmas 
as usual. Sources have however not ruled out the participation of students on what is being called a "voluntary basis." Ruling
 party BJP wants representatives to share the NDA government's 
achievements with the people that day and to draw parallels between the 
six-year rule of the Vajpayee government and the first six months in 
office of the current Narendra Modi government. The BJP's 
lawmakers have also been told to include a two-hour cleanliness drive 
and a feedback session with citizens in their constituencies on 
Christmas, sources said. </div>
