Question: So I saw this code which printed out individual bits of any number.I do not understand why the individual bits are accessed and not the entire number itself

```
#include <stdio.h>
int main()
{
    int x=10, b;   
    for(b=0; x!=0; x>>=1) {
        printf("%d:%d\n", b, (x&1));
        b++;   
    }
}

```

OUTPUT:

```

0:0 
1:1 
2:0 
3:1 

```

Please help me understand this piece of code.

Answer: 
You may correct the code like this :

```
function include_css(){

    wp_enqueue_style('main_css',get_template_directory_uri().'/style.css');
}
add_action('wp_enqueue_scripts','include_css');

```
To enqueue a stylesheet use this in functions.php

```
1.we need to register our stylesheet.
2.we should enqueue it.
3.Hook to an action 
4.call the function where you want to enqueue it.

function include_css()
{
    wp_register_style('main_css',get_template_directory_uri().'/style.css');
    wp_enqueue_style('main_css');
}
add_action('wp_enqueue_scripts','include_css');

```

call,
`<?php wp_head();?>`
in the place you want to enqueue it.(mostly in header.)
