    Implement a CARDIAC machine simulator in C++, that will:

    - Keep track of CARDIAC memory cells in an array of 100 integers (0-99).
    - Keep track of the bug location; which could be an index into the memory array. Watch out for cells 0 and 99; they are special.
    - Read the input tape from a file that starts with a number telling you how many items are on the tape.
    - Output to the screen.

    Running instruction 9xx exits the program.

    An example run of your application would look something like this.

    input.txt (This is our first CARDIAC program with 946 instead of 900 and 002 instead of the blank.)
    18
    002
    800
    030
    004
    020
    130
    021
    200
    022
    631
    023
    531
    024
    321
    025
    946
    002
    820

    Acceptable screen output:
    3
    2
    1
    0

    Operation codes are as follows:

    Code Abbreviation Meaning
    0 INP Copy input to memory.
    1 CLA Copy memory to accumulator.
    2 ADD Add memory to accumulator.
    3 TAC Move bug if accumulator < 0.
    4 SFT Shift accumulator left then right.
    5 OUT Copy memory to output.
    6 STO Copy accumulator to memory.
    7 SUB Subtract memory from accumulator.
    8 JMP Backup bug to 99 then move bug.
    9 HRS move bug and stop computing.

    Solution Preview

    This program is slightly complicated. At a high level it does three things:

    1) Setup and initialize the CARDIAC simulator.
    2) Run the CARDIAC machine.
    3) Output the state of the machine when everything is done.

    Let us look at each of these three stages individually.

    First, setting up the machine is not too complicated. We declare several variables that will be used in the operation of the machine, ...

    Solution Summary

    This solution provides a CARDIAC simulator that uses an array for the machine memory. It is a good example of how to write a machine simulator.
