Use 'MARS' to Solve the problem:

Extend macro.asm to include following two macros:

1. read_int($reg) : To read an integer value from STDIO into given register. For example read_int($t2) will wait for user input for an integer and will store it in register $t2.

2. print_reg_int($reg): To print integer value in given register on STDIO. For example print_reg_int($t2) will print integer value stored in $t2 register on STDIO.

Assemble first.asm (which includes macro.asm) and execute.

The main program should create output on STDIO as following. Please enter a number? 32 You have entered # 32

==============================================================

The given .asm document is as follow:

macro.asm:

first.asm:

=================================================================

The final answer should be only one .asm file. Please help, thank you!
