Building An Assembler

Implementation of the basic functionality of An Assembler, conversion of assembly code to machine code.

Details

This code has two part.

1. hashtable.h

Use the hash table to store user-defined symbol, opcode and register's inforamation.

2. validating assembly code.cpp

Check for valid syntax and convert the assembly code to machine code.

Classes and Functions

hashtable.h

class Hash

1.computeHash(key)--Computes a hashindex forgiven key

2.hasKey(key)--Returns true if key is stored in Table else False

3.addRecord(key,Object)--Inserts a new record into the table

4.getRecord(key)--Returns a record corresponding to the given key

5.replaceRecord(key,Object)--Replaces the record for given key

Collision handling strategy:- Separate Chaining

class HTWrapper

1.saveToFile(filename, HashTable)--Save the hash table to a file for later use.

2.loadFromFile(filename)--load a hash table previously stored in the input file
