CAN SOMEONE PLEASE HELP ME WITH THIS!!!! Build a compiler for Jack -- a modern, object-based, Java-like language. The compiler construction spans two projects: 10 (Syntax Analysis) and 11 (Code Generation). In this project we build a syntax analyzer that parses programs according to the Jack grammar, producing an XML file that reflects the program's structure. main txt // This file is part of the materials accompanying the book // "The Elements of Computing Systems" by Nisan and Schocken, // MIT Press. Book site: www.idc.ac.il/tecs // File name: projects/10/ArrayTest/Main.jack /** Computes the average of a sequence of integers. */ class Main { function void main() { var Array a; var int length; var int i, sum; let length = Keyboard.readInt("HOW MANY NUMBERS? "); let a = Array.new(length); let i = 0; while (i < length) { let a[i] = Keyboard.readInt("ENTER THE NEXT NUMBER: "); let i = i + 1; } let i = 0; let sum = 0; while (i < length) { let sum = sum + a[i]; let i = i + 1; } do Output.printString("THE AVERAGE IS: "); do Output.printInt(sum / length); do Output.println(); return; } } mainT - class Main { function void main ( ) { var Array a ; var int length ; var int i , sum ; let length = Keyboard . readInt ( HOW MANY NUMBERS? ) ; let a = Array . new ( length ) ; let i = 0 ; while ( i < length ) { let a [ i ] = Keyboard . readInt ( ENTER THE NEXT NUMBER: ) ; let i = i + 1 ; } let i = 0 ; let sum = 0 ; while ( i < length ) { let sum = sum + a [ i ] ; let i = i + 1 ; } do Output . printString ( THE AVERAGE IS: ) ; do Output . printInt ( sum / length ) ; do Output . println ( ) ; return ; } }
