A shop will give discount of 10% if the cost of purchased quantity is more than 1000. Ask user for quantity suppose, one unit will cost 100. Judge and print total cost for user. Plz give answer in C++.

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;

Answer:

The code is not dereferencing the pointers. You have to place an asterisk in front of the pointer to read the value the pointer points to.

Explanation:

So "if (str1 != str2)" must be "if (*str1 != *str2)".

likewise:

   while (*str1 != 0 && *str2 != 0)

and

     result = (*str1 == *str2);

Answer:

Power = 1920 Watts or 1.92 Kilowatts

Explanation:

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

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.

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

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.

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<<"%";

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.

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.

II. Associative property: it applies to both multiplication and addition.

III. Distributive property: it is formed using the product of a sum.

IV. Complement property: it involves a variable and its complement.

V. Identity property:

In 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.

Answer:

The procedure in python 3 is as follows:

def add_range(low,high):

   if low<= high:

       total = 0

       for i in range(low,high+1):

           total+=i

       return total

   else:

       return "Failure"

Explanation:

This defines the function/procedure

def add_range(low,high):

If low is less or equal to high

   if low<= high:

Initialize total to 0

       total = 0

Add up numbers in the range

       for i in range(low,high+1):

           total+=i

Return the total

       return total

If low is greater, then return failure

   else:

       return "Failure"
