printer.h

/*
Two Pass Assembler:
	"printer.h" - Part of a set of programs 	
	Includes:
		driver.cpp - maintains the flow of the Assembler while handling serious errors
		lexer.h - provides functions which defines the lexical structure of program and do tokenisation alongwith basic syntax checking
		parser.h - provides functions which gives meaning to the assembly code and convert it to machine/object code
		symbolTable.h - provides functions which builds the symbol tabel for the provided assmebly code with looking for some context specific errors 
		errorHandler.h - provides functions which handles all the errors encountered along the flow of Assmebler 
		helper.h - provides non assembler specific functions which helps in smoothing of operations needed to be done at various points in the flow of Assembler
		printer.h - provides functions which helps in printing the data recieved and information processed 
	Functionality:
		Converts a given assembly code present in some txt file into its adequate machine/object code and writes it down in another txt file
