of any cartoon character will be played and they have to recognize that cartoon
character.\r\n4)They can use lifelines in first 2 rounds like skip a question, take
audience help.\r\n5) The third round will be a rapid fire round. In this round we will
provide them few topics and they need to choose one of them(those topics will be related
to the theme of Riviera, like Indian cricket ,etc.).The participant will be asked
questions on the topic of his choice.\r\n6)The fourth round will be held on the fourth
day. The participant will be given 3 tasks to perform. They are:\r\n---> They will be
given riddles in different languages other than English and Hindi. They need to know
which language it is and solve the riddle. \r\n--->They need to bring outdated posters
from the whole VIT. Specific time limit will be given. \r\n---> They need to get
autographs or photos of tags of organizers and managers of Riviera.\r\n7)Apart from this
audience also will have their set of interesting questions. Their answers will be taken
into consideration and rewards are given to the lucky persons.\r\n",

widely used programming languages of all time and C compilers are available for the

"details":"1) C Language is a general-purpose programming
language .C has facilities for structured programming and allows lexical variable scope
and recursion.\r\n2) Its design provides constructs that map efficiently to typical
machine instructions and therefore it has found lasting use in applications that had
formerly been coded in assembly language.\r\n3) The C programming language uses
libraries as its primary method of extension. In C, a library is a set of functions
contained within a single \"archive\" file. Each library typically has a header file,
which contains the prototypes of the functions contained within the library that may be
used by a program, and declarations of special data types and macro symbols used with
these functions.\r\n4) C has been used successfully for every type of programming
problem imaginable from operating systems to spreadsheets to expert systems - and
efficient compilers are available for machines ranging in power from the Apple Macintosh
to the Cray supercomputers.\r\n5) Tools have been created to help C programmers avoid
some of the problems inherent in the language, such as statements with undefined
behavior or statements that are not a good practice because they are likely to result in
unintended behavior or run-time errors.\r\n6) Despite its low-level capabilities, the
language was designed to encourage cross-platform programming. A standards-compliant and
portably written C program can be compiled for a very wide variety of computer platforms
and operating systems with few changes to its source code\r\n7) With regards to personal
computers Microsoft C for IBM (or clones) PC\'s. and Borlands C are seen to be the two
most commonly used systems. However, the latest version of Microsoft C is now considered
to be the most powerful and efficient C compiler for personal computers.\r\n"
