While appreciating the object-oriented programming paradigm, Stroustrup found Simula too slow. When even BCPL (a predecessor of C, see A Brief History of C for […]

The size of char should be at least 1 byte (most implementations […]

C FAQ: Is there a difference between variable definition and variable declaration?
Posted by Nagesh Rao Published in C, TechnicalYes! Most people seem to think that these two terms are inter-changeable: they are not!

For the first 21 years of life, I only knew the term ‘programming’. It had a mystic quality to it, the whole idea that everything and anything you saw around you could be programmed. Now, programming could be analogous/hardware based, or digital/software based. A simple example could be how your fan is programmed to rotate […]
