Most of us think that c language doesn't support polymorphism. But actually it does, think i am wrong, actually i can prove it to you.. Consider a normal printf statement, it looks something like :               printf("hai"); It also accepts another type of arguments:               printf("%d",&a);  //assume a is an integer variable. Now printf is an in-build function, it accepts two different type of arguments. In the first example it accepts a string variable , in the second one it accepts an integer variable, moreover it accepts different number of arguments, this points to the concept of function overloading which is a branch of polymorphism. C even supports operator overloading: & symbol-- the address operator as most of us  know..but it can also be noted as a bit and operator  too. Hence a single operator can be used for multiple purposes, There is another operator that ...

Google claims that it can identify a robot with just one click. Captches-squiggled text that are used to find spambots. Although it is an effective way to recognize automated bots, it greatly reduces the user experience. To overcome these challenges, Google has designed a Turing Test that can spot a bot requiring it to do very much simple like a “click on a check box” So how does a click of a check box…..can tell google whether you are a human or a robot?.  Google says that the user leave a lot of clues by their way of interaction with the webpage, which reveal that they are actually human, such as the movement of the cursor before a single click,IP address, cookies,etc.. This new method is called “reCaptcha”. Google has tested this reCaptcha in its various services such as wordpress and Humble Bundle(Game sale site), it had an accuracy of 60% in wordpress and 80% in Humble Bundle. As a backup plan if the reCaptcha fails, suppose if there are not enough clues then it automa...
