This time I want to speak on the 'printf' function. Everybody has heard of software vulnerabilities and that functions like 'printf' are outlaw. But it's one thing to know that you'd better not use these functions, and quite the other to understand why. In this article, I will describe two classic...

As it is said, great things are in small ones. Its someway true in C as well. Working on bits rather than bytes, and other bigger data structures leverage implementations in speed and space efficiency. With really high end computers coming up these days, bitwise operations may not be that useful in...

Comma-separated expressions were inherited from C. It's likely that you use such expressions in for- and while-loops rather often. Yet, the language rules in this regard are far from being intuitive. First, let's see what a comma separated expression is. An expression may consist of one or...

As the topic says, self printing programs are nothing but they reproduce themselves as output. Such programs are referred as Quines from the name of the logician Willard van Orman Quine who introduced the concept. I said an 'Ah!!!' when I heard about Quines for first time, spent more hours to...

The other day, I just had this thought of exhausting the R.A.M. of my ailing, old P.C. in the hopes that it may trigger off a cataclysmic crash which would render it useless :happy: (so that I finally get that brand new mega-system P.C. which I so yearn! :D ) So I set out to write this program...

The other day I was working on a code where in I was doing some file related operations. I used the function feof() to test whether the end of file has been reached or not. I got into some trouble over the way I used this function in my code, after debugging a bit I found the problem. The problem...
