Question

Exercise 1: For each of the following high-level language code snippets, write the SRO assembly code. Assume that the variables A, B, C, X. are in memory locations MA, MB, MC, MX, respectively. a) XA+ 2B- 4C; b) if (A <0) else if (A> 0) else c) for (int i 1; 10; i++) X A+B+C (Hint: Use branch instructions to set up the loop)

Answer 1

#include <iostream>

#include <stdio.h>

#include <string>

#include <stdlib.h>

#include <unistd.h> // From http://cs.dvc.edu/HowTo_CSleep.html

using namespace std;

class fibonnaci_series{

public:

fibonnaci_series(int x); // Construction

void push(int n); // Adds a new item to stack

unsigned int pop(); // remove the head guy (the most recently added item)

bool isEmpty(); // check if we have any item added.

void reverse(); // List all items of stack.

  

private:

unsigned*fib; // A pointer to show the head node

unsigned short size; // how many items stack has

};

fibonnaci_series:: fibonnaci_series(int x){

size = 0;

unsigned*fib = new unsigned int(x);

}

// add an item as the head one in the stack

void fibonnaci_series::push(int n)

{

if(n<=1){
  
fib[ size++ ] = n;
  
}
  
for(int i=2;i<=n;i++){
