More registers appear to be a good thing, in terms of reducing the total number of memory accesses a program might require. Give

gulaghasi [49]

Answer:

Following is given the answer step by step:

Explanation:

First of all we will write a program using MARIE that will support the statement: Sum = (A + B) - (C + D). All the necessary comments are given in front of each statement:

Load A # variable A will be loaded

Add B # B will be added to A

Store Temp1 # A + B will be stored in Temp1

Load C # C will be loaded in memory

Add D # D will be added to C

Store Temp2 # C + D will ge stored in Temp2

Load Temp1 # Temp1 will be loaded in the memory

Subt Temp2 # Temp2(A + B) get subtracted from Temp1(A - B)

Store Sum # (A + B) - (C + D) will get stored in Sum.

We can see from above program that memory is accessed 9 times. While if C + D get executed first than memory accesses will be reduced to 7.

Above same program could be written using an architecture of 4 registers:

The program is as follows:

Load R1 , A #A will be loaded into R1

Load R2 , B # B will be loaded into R2

Add R1 , R2 # R2 gets added to R1 and the result is stored in R1 (A + B)

Load R3 , C # C loaded into R3

Load R4 , D # D loaded into R4

Add R3 , R4 # Value in R4 gets added into R3 and R3 becomes (C + D)

#no memory accesses required for this operation

Subt R1 , R4 #R4 (C + D) gets subtracted from R1 (A + B)

#no memory accesses required for this operation

Store Sum # The recent value will be stored into Sum

Here memory is accessed 5 times in total.

#include

gavmur [86]

Answer:

See explaination

Explanation:

#include <fstream>

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

// Fill in the code to define payfile as an input file

ifstream payfile;

float gross;

float net;

float hours;

float payRate;

float stateTax;

float fedTax;

cout << fixed << setprecision(2) << showpoint;

// Fill in the code to open payfile and attach it to the physical file

// named payroll.dat

payfile.open("payroll.dat");

// Fill in code to write a conditional statement to check if payfile

// does not exist.

if(!payfile)

{

cout << "Error opening file. \n";

cout << "It may not exist where indicated" << endl;

return 1;

}

ofstream outfile("pay.out");

cout << "Payrate Hours Gross Pay Net Pay"

<< endl << endl;

outfile << "Payrate Hours Gross Pay Net Pay"

<< endl << endl;

// Fill in code to prime the read for the payfile file.

payfile >> hours;

// Fill in code to write a loop condition to run while payfile has more

// data to process.

while(!payfile.eof())

{

payfile >> payRate >> stateTax >> fedTax;

gross = payRate * hours;

net = gross - (gross * stateTax) - (gross * fedTax);

cout << payRate << setw(15) << hours << setw(12) << gross

<< setw(12) << net << endl;

outfile << payRate << setw(15) << hours << setw(12) << gross

<< setw(12) << net << endl;

payfile >> hours ;// Fill in the code to finish this with the appropriate

// variable to be input

}

payfile.close();

outfile.close();

return 0;

}

g Assignment 8: Driving costs Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon as input, a

zavuch27 [327]

Answer:

miles_gallon = float(input("Enter car's miles/gallon: "))

dollars_gallon = float(input("Enter gas dollars/gallon: "))

print("Gas cost for 20 miles is $", (20 / miles_gallon) * dollars_gallon)

print("Gas cost for 75 miles is $", (75 / miles_gallon) * dollars_gallon)

print("Gas cost for 500 miles is $", (500 / miles_gallon) * dollars_gallon)

Explanation:

*The code is in Python.

Ask the user to enter the car's miles/gallon and gas dollars/gallon

Calculate the gas cost for 20 miles, divide 20 by miles_gallon and multiply the result by dollars_gallon, then print it

Calculate the gas cost for 75 miles, divide 75 by miles_gallon and multiply the result by dollars_gallon, then print it

Calculate the gas cost for 500 miles, divide 500 by miles_gallon and multiply the result by dollars_gallon, then print it
