Cindy tried to delete a customer but the customer still had open invoices so the system would not allow her to delete the customer. More than likely ________ was enforced.
Answers
Answer:
The answer is "Referential integrity".
Explanation:
This relates to one aspect of data integrity. Data across multiple tables are linked via relationships. In view of the distinct customer & invoice tables, each invoice table should have the primary key specified throughout the Customer table, for instance. Whenever the invoice table contains a customer ID reference. This ID including its customer will be only a table of the customer.
In this lab, you complete a C++ program that uses an array to store data for the village of Marengo.
The program is described in Chapter 8, Exercise 5, in Programming Logic and Design. The program should allow the user to enter each household size and determine the mean and median household size in Marengo. The program should output the mean and median household size in Marengo. The file provided for this lab contains the necessary variable declarations and input statements. You need to write the code that sorts the household sizes in ascending order using a bubble sort and then prints the mean and median household size in Marengo. Comments in the code tell you where to write your statements.
Instructions
Make sure that the file HouseholdSize.cpp is selected and open.
Write the bubble sort.
Output the mean and median household size in Marengo.
Execute the program by clicking the Run button and the bottom of the screen.
Enter the following input, and ensure the output is correct. Household sizes: 4, 1, 2, 4, 3, 3, 2, 2, 2, 4, 5, 6 followed by 999 to exit the program.
Here is my code so far. I need help finishing it (printing the mean & median, etc). Thanks so much:
// HouseholdSize.cpp - This program uses a bubble sort to arrange up to 300 household sizes in
// descending order and then prints the mean and median household size.
// Input: Interactive.
// Output: Mean and median household size.
#include
#include
using namespace std;
int main()
{
// Declare variables.
const int SIZE = 300; // Number of household sizes
int householdSizes[SIZE]; // Array used to store 300 household sizes
int x;
int limit = SIZE;
int householdSize = 0;
int pairsToCompare;
bool switchOccurred;
int temp;
double sum = 0;
double mean = 0;
double median = 0;
// Input household size
cout << "Enter household size or 999 to quit: ";
cin >> householdSize;
// This is the work done in the fillArray() function
x = 0;
while(x < limit && householdSize != 999)
{
// Place value in array.
householdSizes[x] = householdSize;
// Calculate total of household sizes
sum+= householdSizes[x];
x++; // Get ready for next input item.
cout << "Enter household size or 999 to quit: ";
cin >> householdSize;
} // End of input loop.
limit = x;
// Find the mean
// This is the work done in the sortArray() function

switchOccured == false;
while (x < pairsToCompare)
{
if(householdSizes[x]) > householdSizes[x+1])
{
//perform switch
}
x++;
}
pairsToCompare--;
}
// This is the work done in the displayArray() function
//Print the mean
// Find the median
median = (limit-1) / 2;
if (limit % 2 ==0)
{
cout << "Median is: " << (householdSizes[(int)median] + householdSizes[(int)median + 1]) / 2.0 << endl;
}
else {
// Print the median household size
}
// Print the median
return 0;
} // End of main function
Answers
Answer:
For the mean, do the following:
mean = sum/limit;
cout<<"Mean: "<<mean;
For the median do the following:
for(int i = 0; i<limit; i++) {
for(int j = i+1; j<limit; j++){
if(householdSizes[j] < householdSizes[i]){
temp = householdSizes[i];
householdSizes[i] = householdSizes[j];
householdSizes[j] = temp; } } }
median= (householdSizes[(limit-1)/2]+householdSizes[1+(limit-1)/2])/2.0;
if((limit - 1)%2==0){
median = householdSizes[limit/2];
}
cout<<endl<<"Median: "<<median;
Explanation:
The bubble sort algorithm in your program is not well implemented;
So, I replaced the one in your program with another.
Also, some variable declarations were removed (as they were no longer needed) --- See attachment for complete program
Calculate mean
mean = sum/limit;
Print mean
cout<<"Mean: "<<mean;
Iterate through each element
for(int i = 0; i<limit; i++) {
Iterate through every other elements forward
for(int j = i+1; j<limit; j++){
Compare both elements
if(householdSizes[j] < householdSizes[i]){
Reposition the elements if not properly sorted
temp = householdSizes[i];
householdSizes[i] = householdSizes[j];
householdSizes[j] = temp; } } }
Calculate the median for even elements
median= (householdSizes[(limit-1)/2]+householdSizes[1+(limit-1)/2])/2.0;
Calculate the median for odd elements
if((limit - 1)%2==0){
median = householdSizes[limit/2];
}
Print median
cout<<endl<<"Median: "<<median;
Suppose a computer using set associative cache has 221 bytes of main memory, and a cache of 64 blocks, where each cache block contains 4 bytes. a) If this cache is 2-way set associative, what is the format of a memory address as seen by the cache, i.e., what are the sizes of the tag, set, and offset fields
Answers
Answer:
Tag = 1
Index = 5
Block offset = 2
Explanation:
From the given information:
The main memory bits(MM) = 221
number of block in the cache = 64 blocks
Block size = 4B
Recall that;
MM = log (memory size)
Thus;
main memory bits = log (221)
= 8 bits
Since this is a 2-way assoicative set;
the number of set in each cache = block size/2
64/2 = 32
Now, the index bit = log( no of set in each cache)
= log(32)
= 5 bits
Also since block size = 4B;
the block offset = log(4) = 2 bits
As such, tag = main memory bits - (index bit + block offset)
tag = 8 -(5 + 2)
tag = 8 -7
tag = 1
Write a program that grades arithmetic quizzes as follows: Ask the user how many questions are in the quiz. Ask the user to enter the key (that is, the correct answers). There should be one answer for each question in the quiz, and each answer should be an integer. They can be entered on a single line, e.g., 34 7 13 100 81 3 9 10 321 12 might be the key for a 10-question quiz. You will need to store the key in an array. Ask the user to enter the answers for the quiz to be graded. As for the key, these can be entered on a single line. Again there needs to be one for each question. Note that these answers do not need to be stored; each answer can simply be compared to the key as it is entered. When the user has entered all of the answers to be graded, print the number correct and the percent correct.
Answers
Answer:
The program in C++ is as follows:
#include <iostream>
using namespace std;
int main(){
int questions, answer;
cout<<"Questions: ";
cin>>questions;
int answerkey[questions];
cout<<"Enter answer keys: ";
for(int i = 0; i< questions; i++){
cin>>answerkey[i]; }
int correct = 0;
cout<<"Enter answers: ";
for(int i = 0; i< questions; i++){
cin>>answer;
if(answer == answerkey[i]){
correct++; } }
cout<<"Correct answers: "<<correct<<endl;
cout<<"Percentage correct : "<<(100 * correct)/questions<<"%";
return 0;
}
Explanation:
This declares the number of questions and the answers submitted to each equation
int questions, answer;
Prompt to get the number of questions
cout<<"Questions: ";
This gets input for the number of questions
cin>>questions;
This declares the answerkey as an array
int answerkey[questions];
Prompt to get the answer key
cout<<"Enter answer keys: ";
This iteration gets the answer key for each question
for(int i = 0; i< questions; i++){
cin>>answerkey[i]; }
This initializes the number of correct answers to 0
int correct = 0;
Prompt to get the enter the answers
cout<<"Enter answers: ";
This iterates through the answer keys
for(int i = 0; i< questions; i++){
This gets the answer to each question
cin>>answer;
This compares the answer to the answer key of the question
if(answer == answerkey[i]){
If they are the same, correct is incremented by 1
correct++; } }
Print the number of correct answers
cout<<"Correct answers: "<<correct<<endl;
Print the percentage of correct answers
cout<<"Percentage correct : "<<(100 * correct)/questions<<"%";

Given the following data;
Resistance = 30 Ohms
Voltage = 240 Volts
To find power rating of the kettle;
Mathematically, the power consumption of an electric device is given by the formula;
Power = voltage²/resistance
Substituting into the formula, we have;
Power = 240²/30
Power = 57600/30
Power = 1920 Watts or 1.92 Kilowatts

explain 5 important of using a word processor
Answers
Answer:
Spelling
Word processors contain an electronic spell checker. The student writer has immediate feedback about misspelled words. Student must discern which of the computer-generated spellings is correct for the context. Teachers no longer have to red-ink spelling errors. They can focus on the few exceptions the spellchecker does not catch.
Security
Teachers and students gain a sense of security about losing assignments. When the student saves her work, she avoids the possibility of the assignment being lost or misplaced. If an assignment is ever misplaced, a replacement can be easily printed.
Legibility
Teachers benefit by receiving a readable copy that is easy to grade. Students with poor handwriting can increase their scores with better looking papers. Students should be instructed to turn in copies of work in a readable font.
Publishing
Work done on a word processor can easily published on a bulletin board. Teachers can create electronic anthologies of their students' writings. Each student can receive an electronic copy of published works with no printing costs.
Mobility
Work done on a word processor and saved on the Internet is highly portable and accessible from any computer with Internet access. Dogs do not eat papers in cyberspace. "I forgot it at home" is irrelevant. Just log onto the nearest computer and your work appears on the screen.

If myClass has a constructor with a parameter of type String, select the other constructor that should be included.
a. public void myClass( ) {. . .}
b. public myClass(int value ) {. . .}
c. public myClass(String str1, String str2) {. . .}
d. public myClass( ) {. . .}
Answers
Answer:
d. public myClass( ) {. . .}
Explanation:
A constructor is a special method that is called when an object of a class is created. It is also used to initialize the instance variables of the given class. A class may have one or more constructors provided that these constructors have different signatures. A class that does not have a constructor explicitly defined has a default parameterless constructor.
Having said these about a constructor, a few other things are worth to be noted by a constructor.
i. In Java, a constructor has the same name as the name of its class.
For example, in the given class myClass, the constructor(s) should also have the name myClass.
ii. A constructor does not have a return value. It is therefore wrong to write a constructor like this:
public void myClass(){...}
This makes option a incorrect.
iii. When a constructor with parameters is defined, the default parameterless constructor is overridden. This might break the code if some other parts of the program depend on this constructor. So it is advisable to always explicitly write the default parameterless constructor.
This makes option d a correct option.
Other options b and c may also be correct but there is no additional information in the question to help establish or justify that.

g Boolean Algebraic properties _____. a. are used to make boolean expressions more complicated b. are used to convert a Boolean equation to a circuit c. can lead to a simpler expression and thus a simpler circuit d. can be used with integer numbers
Answers
Answer:
c. can lead to a simpler expression and thus a simpler circuit.
Explanation:
Boolean logic refers to a theory of mathematics developed by the prominent British mathematician, called George Boole. In Boolean logic, all variables are either true or false and are denoted by the number "1" or "0" respectively; True = 1 or False = 0.
Also, Boolean logic allow users to combine keywords with Boolean operators (quotes, AND, OR, near/n) to give a more personalized and relevant search results.
There are five (5) main Boolean Algebraic properties and these includes;
I. Commutative property: it applies to both multiplication and addition.
For addition; A + B = B + AFor multiplication; A.B = B.AII. Associative property: it applies to both multiplication and addition.
For addition; A + (B + C) = (A + B) + CFor multiplication; A(BC) = (AB)CIII. Distributive property: it is formed using the product of a sum.
A(B + C) = AB + ACIV. Complement property: it involves a variable and its complement.
For addition: A + A' = 1For multiplication; A.A' = 0V. Identity property:
For addition; A + 0 = AFor multiplication; A.1 = AIn digital electronics, Boolean expressions are used to represent circuits which comprises of Boolean operations and as such simplifying any logic expression without changing or altering any of it's functionalities and properties based on given operations or variables.
Hence, Boolean Algebraic properties can lead to a simpler expression and thus a simpler circuit.
