I need to make a diagram showing how a 12‐bit main memory address is partitioned into the block offset, set index, and tag fields for addressing the cache. Show clearly the bit positions of the 12‐bit address occupied by each field. …

I'm attempting to make a C program that builds a concordance from a piece of text. I need my program to: 1. read the text consisting of one more lines from standard input. 2. parse the lines into individual words and store each word in lower case into a word …

I'm trying to make a calendar out of C. I need it to be able to promt the user for a month, and the year, and it should then print the calendar of that. So far the code I've got is: #include<stdio.h> int days_in_month[]= {0,31,28,31,30,31,30,31,31,30,31,30,31}; char *months[]= { " ", …

I'm trying to make a calculator of a sort in python that works on a local web server. I have the localhost all set up and all. import cgi data = cgi.FieldStorage() product_description = data.getvalue('product_description') list_price = data.getvalue('list_price') discount_percent = data.getvalue('discount_percent') total = data.getvalue('total') def total_price(): data.getvalue('total') - discount return …

I'm trying to modify this code: class Tree: def __init__(self, cargo, left=None, right=None): self.cargo = cargo self.left = left self.right = right def __str__(self): return str(self.cargo) def print_tree_inorder(tree): if tree is None: return print_tree_inorder(tree.left) print(tree.cargo, end=" ") print_tree_inorder(tree.right) So that it adds parentheses around every operator and pair of operands. …

I'm trying to write a boolean function that takes two Mytime objects, t1 and t2 as arguments, and returns True if the object falls inbetween the two times. This is a question from the How to Think Like a Computer Scientist book, and I need help. What I've gotten so …

I wanted to format this string but I don't know how I can do the formatting part at all. class MyTime: def __init__(self, hrs=0, mins=0, secs=0): self.hours = hrs self.minutes = mins self.seconds = secs if self.seconds >= 60: self.minutes += self.seconds // 60 self.seconds = self.seconds % 60 if …

This is my code: class MyTime: def __init__(self, hrs=0, mins=0, secs=0): self.hours = hrs self.minutes = mins self.seconds = secs if self.seconds >= 60: self.minutes += self.seconds // 60 self.seconds = self.seconds % 60 if self.minutes >= 60: self.hours += self.minutes // 60 self.minutes = self.minutes % 60 if self.hours …

I'm trying to create a program that will prompt the user for a list of text files to read from, then read those text files and build a dictionary of all the unique words found. Then finally put those unique words into another file and make it alphabetical order from …

My Rational class code: from __future__ import division import math as _math def _gcf(a, b): # Returns the greatest common factor of a and b. a = abs(a) b = abs(b) while b: a, b = b, a % b return a class Rational(object): def __init__(self, numerator=0, denominator=1): # Contructs …

Python keeps getting stuck on this line because there is no attribute "numerator" (and I'm assuming it'd say it has no attribute for denominator either). third = Rational(25, 10) print ("third: 0/1".format(third.numerator(), third.denominator())) For my Rational class, I've got def gcd(a, b): if b == 0: return a else: return …
