Your simulator must run from the command line with a single input file as a parameter to main. This file will contain a sequence of instructions for your simulator to store in "Instruction Memory" and then run via the fetch/execute cycle. In the input file each instruction is represented with two integers: the first one represents the opcode and the second one a memory address or a device number depending on the instruction.

Question
### Input Specifications Your simulator must run from the command line with a single input file as a parameter to main. This file will contain a sequence of instructions for your simulator to store in "Instruction Memory" and then run via the fetch/execute cycle. In the input file, each instruction is represented with two integers: the first one represents the opcode and the second one a memory address or a device number depending on the instruction. #### Example: **Input File** ``` 5 5 // IN 5 6 7 // OUT 7 3 0 // STORE 0 5 5 // IN 5 6 7 // OUT 7 3 1 // STORE 1 1 0 // LOAD 0 4 1 // SUB 1 3 0 // STORE 0 6 7 // OUT 7 1 1 // LOAD 1 6 7 // OUT 7 7 0 // END ``` ### Output Specifications Your simulator should provide output according to the input file. Along with this output, your program should provide status messages identifying details on the workings of your simulator. Output text does not have to reflect the example word-for-word, but please provide detail on the program as it runs in a readable format that does not conflict with the actual output of your simulator. After each instruction, print the current state of the Program Counter, Accumulator, and Data Memory. The INPUT instruction is the only one that should prompt an interaction from the user.

**The Problem** Using the C programming language, write a program that simulates a variant of the Tiny Machine Architecture. In this implementation, memory (RAM) is split into Instruction Memory (IM) and Data Memory (DM). Your code must implement the basic instruction set architecture (ISA) of the Tiny Machine Architecture: 1. 1 → LOAD 2. 2 → ADD 3. 3 → STORE 4. 4 → SUB 5. 5 → IN 6. 6 → OUT 7. 7 → END 8. 8 → JMP 9. 9 → SKIPZ Each piece of the architecture must be accurately represented in your code (Instruction Register, Program Counter, Memory Address Registers, Instruction Memory, Data Memory, Memory Data Registers, and Accumulator). Data Memory will be represented by an integer array. Your Program Counter will begin pointing to the first instruction of the program. **For the sake of simplicity, Instruction Memory (IM) and Data Memory (DM) may be implemented as separate arrays.** **Hint:** Implementing a struct for your Instructions and an array of these structs as your Instruction Memory greatly simplifies this program. **Example:** ```c typedef struct { int opCode, deviceOrAddress; } Instruction; Instruction IM[MAXPROGRAMSIZE]; ``` **Note:** IM, MDR1, and IR are of type Instruction. All other CPU registers and Data Memory (DM) are of type int.
