(Modifications to the Simpletron Simulator) In Exercise, you wrote a software simulation of a computer that executes programs written in Simpletron Machine Language (SML). In this exercise, we propose several modifications and enhancements to the Simpletron Simulator. In Exercises, we propose building a compiler that converts programs written in a high-level programming language (a variation of BASIC) to Simpletron Machine Language. Some of the following modifications and enhancements may be required to execute the programs produced by the compiler.

a) Extend the Simpletron Simulator's memory to contain 1000 memory locations to en-able the Simpletron to handle larger programs.

b) Allow the simulator to perform remainder calculations. This requires an additional Simpletron Machine Language instruction.

c) Allow the simulator to perform exponentiation calculations. This requires an additional Simpletron Machine Language instruction.

d) Modify the simulator to use hexadecimal values rather than integer values to represent Simpletron Machine Language instructions.

e) Modify the simulator to allow output of a newline. This requires an additional Simpletron Machine Language instruction.

f) Modify the simulator to process floating-point values in addition to integer values.

g) Modify the simulator to handle string input. [Hint: Each Simpletron word can be divided into two groups, each holding a two-digit integer. Each two-digit integer represents the ASCII decimal equivalent of a character. Add a machine-language instruction that will input a string and store it beginning at a specific Simpletron memory location. The first half of the word at that location will be a count of the number of characters in the string (i.e., the length of the string). Each succeeding half word contains one ASCII character expressed as two decimal digits. The machine-language instruction converts each character into its ASCII equivalent and assigns it to a half word.]

h) Modify the simulator to handle output of strings stored in the format of part (g). [Hint: Add a machine-language instruction that prints a string beginning at a specified Simpletron memory location. The first half of the word at that location is the length of the string in characters. Each succeeding half word contains one ASCII character expressed as two decimal digits. The machine-language instruction checks the length and prints the string by translating each two-digit number into its equivalent character.]
