title: The showbits() function
body: <p>While reading a book called "Let us C" I read that a function <code>showbit()</code> exists which can show you the bits of the number. There wasn't any special header file mentioned for it. Searched for it on the internet and didn't found anything useful. <strong>Is there such a function</strong>? I want this to print the binary of decimal numbers. Else please give me a replacement function. Thanks</p>
