In this project, you will create a simple assembler program for the MIPS assembly language. Your program receives the source code filename $($for example mycode.asm$),$ translates each instruction into the machine code$($HEX or Binary$),$ and stores them with their associated address in an output file with the same name as the input file but with $.$obj extension.

For Simplicity, only consider the following MIPS instructions:

ADD, SUB, AND, OR $($R$-$type$)$

ADDI, ANDI, SLL $($I$-$Type$)$

BEQ, BNE $($I$-$type$)$

J $($J$-$type$)$

The source code in the input file can contain several instructions with different types, The target address of BEG, BNE, and J instructions are determined by labels in the source code.

The start Address of the program is $0$x$00400000$
