Liang-Bosky line clipping algorithm

 Lian -Bosky line clipping algorithm


starting point (t=0) and ending point (t=x) base on time interval we can calculate instruction point,

                                                

                             initial point(t=0)                   p(x,y)  t                  final point(t=1)

                                                    A----------------/---------------------B

                                               (x1,y1) (1-t)                                  (x2,y2)

                                         

                                             x=? and y=?  is value of p

                                           x=x2t+(1-t)x1

x=x2t+x1-x1t

x=x1+x2t-x1

x=x1+

Describe the synthesis analysis model of compiler? in compiler designer. or Explain in detail the process of compilation? in compiler designer

  what is compiler? compiler is a program that convert high level language into machine level language. compiler is scans all the lines of source program and list out all syntax error at a time. A compiler contain six phases which are as fallows.  1:  phase 1 (Lexical analysis):  a  : The lexical analyzer is also called scanner.          b : The lexical analyzer phase takes source program as input and separates characters of  source language into group of sting called token. c : operator symbols such as >,>=,+,etc punctuation symbols such as parenthesis or commas. 2. phase 2(syntax analyzer): a : the syntax analyzer phase is also called parsing phase. b : the syntax analyzer group tokens together into syntactic structure . c : the output of this is parse tee. 3: phase 4 (semantic analyzer ): a: the semantic analyzer phase check the source program for semantic error and gather type            ...
