Mpp-Project

History of Some Programing Languages



PHP

PHP



    
  • Created in 1994
  • A series of CGI Perl scripts
  • Rewrited in C To be more performant
  • Criticized by many people
  • Used by 200 million web sites including facebook ...

Scala

  • Started in 2001 at EPFL .
  • By Odersky who had previously worked on Gj .
  • Released in 2003 , released publicly on the Java plateform
 //javaint mathFunction(int num) {int numSquare = num*num;return (int) (Math.cbrt(numSquare) +Math.log(numSquare));}
//Scaladef mathFunction(num: Int): Int = {var numSquare: Int = num*numreturn (math.cbrt(numSquare) + math.log(numSquare)).asInstanceOf[Int]}

Scheme

  • One of the two main dialects of Lisp
  • Developed at the Mit AI Lab
  • Written as  a tiny Lisp interpreter using Maclisp

(define-syntax let(syntax-rules ()((let ((var expr) ...) body ...)((lambda (var ...) body ...) expr ...))))

How Mpp was done



Steps

  • Introducing to the libc dev
  • Structure of functions
  • Explaining some functions
  • Showing some Mpp functions
  • mpp.h

Libc dev

  • Implementation of C  Standard library
  • Written by Roland McGrath



Stdio.h

  • A part of the libc
  • The mpp.h is a miniature of stdio.h
Structure of the stdio.h functions
  • The Printf function

 int printf(const char* format, ...);
  • The scanf function

 int scanf(const char * format, ...);
  • The fprintf function 

 int fprintf(FILE *stream, const char *format, ...)
  • The fscanf function 

 int fprintf(FILE *stream, const char *format, ...)
