Its aim is to teach C to a beginner, but with enough of the details so as not be outgrown as the years go by. It presumes that you have some previous acquittance with programming - you need to know what a variable is and what a function is - but you do not need much experience. It is not essential to follow the order of the chapters rigorously, but if you are a beginner to C it is recommended. When it comes down to it, most languages have basically the same kinds of features: variables, ways of making loops, ways of making decisions, ways of accessing files etc. If you want to plan your assault on C, think about what you already know about programming and what you expect to look for in C. You will most likely find all of those things and more, as you work though the chapters.\";s:5:\"thumb\";s:37:\"images/t/1/c-programming-tutorial.jpg\";s:6:\"thumb2\";s:38:\"images/t2/1/c-programming-tutorial.jpg\";s:9:\"permalink\";s:22:\"c-programming-tutorial\";s:5:\"pages\";s:3:\"410\";s:6:\"rating\";s:6:\"3.4375\";s:5:\"voter\";s:2:\"16\";}i:4;O:8:\"stdClass\":13:{s:2:\"id\";s:6:\"180184\";s:6:\"status\";s:8:\"verified\";s:11:\"author_name\";s:10:\"nishagoyal\";s:9:\"author_id\";s:5:\"54357\";s:14:\"author_website\";s:0:\"\";s:5:\"title\";s:40:\"Concavity and the Second Derivative Test\";s:11:\"description\";s:797:\"What do you understand by concavity and the second derivative test? Before\nmoving to this, first start with Concavity as you can’t understand anything about\nsecond derivative test without learning concavity.\nSuppose f is differentiable on an open interval I. The graph of f is concave\nupward on I if the f\' is increasing on the interval or f\'\' is positive in the interval I.\nAnd if we see that the graph of f is concave downward on I if the f\' is decreasing\non the interval or f\'\' is negative in the interval I.\nComing to second derivative test let’s assume that two differentiable function\nhas a relative maximum at x=c then the derivative is positive to the left of c and\nnegative to the right of c.
