4 reasons why users attach speakers
to their computers
Answer: we connected speakers with computers for listening voices or sound because the computer has not their own speaker. the purpose of speakers is to produce audio output that can be heard by the listener. Speakers are transducers that convert electromagnetic waves into sound waves. The speakers receive audio input from a device such as a computer or an audio receiver.

web analytics can tell you many things about your online performance, but what can analytics tools not tell you
Answer:
The answer is below
Explanation:
While web analytics such as Góogle analysts is known to help online marketers to map out a clear strategy and thereby improve their outreach, there are still some specific things the current web analytics can not do for the user. For example:
1. Web Analytics can’t accurately track leads
2. Web Analytics can’t track lead quality
3. Web Analytics can’t track the full customer journey
4. Web Analytics can’t highlight the true impact of payment.
Write a function that takes number between 1 and 7 as a parameter and prints out the corresponding number as a string. For example, if the parameter is 1, your function should print out one. If the parameter is 2, your function should print out two, etc. If the parameter is not between 1 and 7, the function should print an appropriate error message. In your file, you should include a main() that allows the user to enter a number and calls your function to demonstrate that it works.
Answer:
The program in C++ is as follows:
#include<iostream>
using namespace std;
void changenum(int num){
string nums[7] = {"One","Two","Three","Four","Five","Six","Seven"};
if(num >7 || num < 1){
cout<<"Out of range";
}
else{
cout<<nums[num-1]; }
}
int main(){
int num;
cout<<"Number: ";
cin>>num;
changenum(num);
return 0;
}
Explanation:
The function begins here
void changenum(int num){
This initializesa string of numbers; one to seven
string nums[7] = {"One","Two","Three","Four","Five","Six","Seven"};
If the number is less than 1 or greater than 7, it prints an out of range error
if(num >7 || num < 1){
cout<<"Out of range";
}
If otherwise, the corresponding number is printed
else{
cout<<nums[num-1]; }
}
The main begins here
int main(){
This declares num as integer
int num;
Prompt the user for input
cout<<"Number: ";
Get input from the user
cin>>num;
Pass the input to the function
changenum(num);
return 0;
}

Answer:
"Digital literacy" would be the appropriate solution.
Explanation:
Capable of navigating and understanding, evaluating as well as communicating on several digital channels, is determined as a Digital literacy.Throughout the same way, as media literacy requires the capability to recognize as well as appropriately construct publicity, digital literacy encompasses even ethical including socially responsible abilities.You are responsible for a rail convoy of goods consisting of several boxcars. You start the train and after a few minutes you realize that some boxcars are overloaded and weigh too heavily on the rails while others are dangerously light. So you decide to stop the train and spread the weight more evenly so that all the boxcars have exactly the same weight (without changing the total weight). For that you write a program which helps you in the distribution of the weight.
Your program should first read the number of cars to be weighed (integer) followed by the weights of the cars (doubles). Then your program should calculate and display how much weight to add or subtract from each car such that every car has the same weight. The total weight of all of the cars should not change. These additions and subtractions of weights should be displayed with one decimal place. You may assume that there are no more than 50 boxcars.
Example 1
In this example, there are 5 boxcars with different weights summing to 110.0. The ouput shows that we are modifying all the boxcars so that they each carry a weight of 22.0 (which makes a total of 110.0 for the entire train). So we remove 18.0 for the first boxcar, we add 10.0 for the second, we add 2.0 for the third, etc.
Input
5
40.0
12.0
20.0
5. 33.
0
Output
- 18.0
10.0
2.0
17.0
-11.0
Answer:
The program in C++ is as follows:
#include <iostream>
#include <iomanip>
using namespace std;
int main(){
int cars;
cin>>cars;
double weights[cars];
double total = 0;
for(int i = 0; i<cars;i++){
cin>>weights[i];
total+=weights[i]; }
double avg = total/cars;
for(int i = 0; i<cars;i++){
cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl; }
return 0;
}
Explanation:
This declares the number of cars as integers
int cars;
This gets input for the number of cars
cin>>cars;
This declares the weight of the cars as an array of double datatype
double weights[cars];
This initializes the total weights to 0
double total = 0;
This iterates through the number of cars
for(int i = 0; i<cars;i++){
This gets input for each weight
cin>>weights[i];
This adds up the total weight
total+=weights[i]; }
This calculates the average weights
double avg = total/cars;
This iterates through the number of cars
for(int i = 0; i<cars;i++){
This prints how much weight to be added or subtracted
cout<<fixed<<setprecision(1)<<avg-weights[i]<<endl; }
The divBySum method is intended to return the sum ofall the elements in the int arrayparameter arr that are divisible by the intparameter num. Consider the following examples, in whichthe array arrcontains {4, 1, 3, 6, 2, 9}.The call divBySum(arr, 3) will return 18,which is the sum of 3, 6, and 9,since those are the only integers in arr that aredivisible by 3.The call divBySum(arr, 5) will return 0,since none of the integers in arr are divisibleby 5.Complete the divBySum method using anenhanced for loop. Assume that arr isproperly declared and initialized. The method must use anenhanced for loop to earn full credit./** Returns the sum of all integers inarr that are divisible by num* Precondition: num > 0*/public static int divBySum(int[] arr, int num)
Answer:
Explanation:
The following program is written in Java and creates the divBySum method using a enhanced for loop. In the picture attached below I have provided an example of the output given if called using the array provided in the question and a divisible parameter of 3.
public static int divBySum(int[] arr, int num) {
int sum = 0;
for (int x : arr) {
if ((x % num) == 0) {
sum += x;
}
}

Imagine that you are helping to build a store management system for a fast food restaurant. Given the following lists, write a program that asks the user for a product name. Next, find out if the restaurant sells that item and report the status to the user. Allow the user to continue to inquire about product names until they elect to quit the program.
Answer:
The program in python is as follows:
def checkstatus(food,foodlists):
if food in foodlists:
return "Available"
else:
return "Not Available"
foodlists = ["Burger","Spaghetti","Potato","Lasagna","Chicken"]
for i in range(len(foodlists)):
foodlists[i] = foodlists[i]. lower()
food = input("Food (Q to quit): ").lower()
while food != "q":
print("Status: ",checkstatus(food,foodlists))
food = input("Food (Q to quit): ").lower()
Explanation:
The program uses function.
The function is defines here. It accepts as input, a food item and a food list
def checkstatus(food,foodlists):
This check if the food is in the food lists
if food in foodlists:
Returns available, if true
return "Available"
Returns Not available, if otherwise
else:
return "Not Available"
The main begins here.
The food list is not given in the question. So, I assumed the following list
foodlists = ["Burger","Spaghetti","Potato","Lasagna","Chicken"]
This converts all items of the food list to lowercase
for i in range(len(foodlists)):
foodlists[i] = foodlists[i]. lower()
Prompt the user for food. When user inputs Q or q, the program exits
food = input("Food (Q to quit): ").lower()
This is repeated until the user quits
while food != "q":
Check and print the status of the food
print("Status: ",checkstatus(food,foodlists))
Prompt the user for another food
food = input("Food (Q to quit): ").lower()
You will write code to manipulate strings using pointers but without using the string handling functions in string.h. Do not include string.h in your code. You will not get any points unless you use pointers throughout both parts.
You will read in two strings from a file cp4in_1.txt at a time (there will be 2n strings, and you will read them until EOF) and then do the following. You alternately take characters from the two strings and string them together and create a new string which you will store in a new string variable. You may assume that each string is no more than 20 characters long (not including the null terminator), but can be far less. You must use pointers. You may store each string in an array, but are not allowed to treat the string as a character array in the sense that you may not have statements like c[i] = a[i], but rather *c *a is allowed. You will not get any points unless you use pointers.

The hexadecimal equivalent
of 22210 is DE
The binary equivalent of
D7 is 11010011
The decimal equivalent of
1316 is 19.
True
False
Answer:
[tex](a)\ 222_{10} = DE_{16}[/tex] --- True
[tex](b)\ D7_{16} = 11010011_2[/tex] --- False
[tex](c)\ 13_{16} = 19_{10}[/tex] --- True
Explanation:
Required
Determine if the statements are true or not.
[tex](a)\ 222_{10} = DE_{16}[/tex]
To do this, we convert DE from base 16 to base 10 using product rule.
So, we have:
[tex]DE_{16} = D * 16^1 + E * 16^0[/tex]
In hexadecimal.
[tex]D =13 \\E = 14[/tex]
So, we have:
[tex]DE_{16} = 13 * 16^1 + 14 * 16^0[/tex]
[tex]DE_{16} = 222_{10}[/tex]
Hence:
(a) is true
[tex](b)\ D7_{16} = 11010011_2[/tex]
First, convert D7 to base 10 using product rule
[tex]D7_{16} = D * 16^1 + 7 * 16^0[/tex]
[tex]D = 13[/tex]
So, we have:
[tex]D7_{16} = 13 * 16^1 + 7 * 16^0[/tex]
[tex]D7_{16} = 215_{10}[/tex]
Next convert 215 to base 2, using division rule
[tex]215 / 2 = 107 R 1[/tex]
[tex]107/2 =53 R 1[/tex]
[tex]53/2 =26 R1[/tex]
[tex]26/2 = 13 R 0[/tex]
[tex]13/2 = 6 R 1[/tex]
[tex]6/2 = 3 R 0[/tex]
[tex]3/2 = 1 R 1[/tex]
[tex]1/2 = 0 R1[/tex]
Write the remainders from bottom to top.
[tex]D7_{16} = 11010111_2[/tex]
Hence (b) is false
[tex](c)\ 13_{16} = 19_{10}[/tex]
Convert 13 to base 10 using product rule
[tex]13_{16} = 1 * 16^1 + 3 * 16^0[/tex]
[tex]13_{16} = 19[/tex]
Hence; (c) is true

The new software organization requires a new point of sale and stock control system for their many stores throughout Pakistan to replace their aging mini-based systems.
A sales assistant will be able to process an order by entering product numbers and required quantities into the system. The system will display a description, price, and available stock. In-stock products will normally be collected immediately by the customer from the store but may be selected for delivery to the customer's home address for which there will be a charge. If stock is not available, the sales assistant will be able to create a backorder for the product from a regional warehouse. The products will then either be delivered directly from the regional warehouse to the customer's home address, or the store for collection by the customer. The system will allow products to be paid for by cash or credit card. Credit card transactions will be validated via an online card transaction system. The system will produce a receipt. Order details for in-stock products will be printed in the warehouse including the bin reference, quantity, product number, and description. These will be collected by the sales assistant and given to the customer. The sales assistant will be able to make refunds, provided a valid receipt is produced. The sales assistant will also be able to check stock and pricing without creating an order and progress orders that have been created for delivery.

a) 2 4 8 16 32 End
b) 2 2 2 2 2
c) 2 4 8 16 32 64 End
d) 2 4 8 16 32
Answer:
The output of the program is:
2 4 8 16 32 64 End
Explanation:
See attachment for proper presentation of the program
The program uses recursion to determine its operations and outputs.
The function is defined as: myMathFunction(int a, int r, int counter)
It initially gets the following as its input from the main method
a= 1; r = 2; counter = 0
Its operation goes thus:
val = a*r; 1 * 2 = 2
Print val; Prints 2
if (counter > 4) { System.out.print("End"); } : Not true
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 2; r = 2; counter = 1
val = a*r; 2 * 2 = 4
Print val; Prints 4
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 4; r = 2; counter = 2
val = a*r; 4 * 2 = 8
Print val; Prints 8
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 8; r = 2; counter = 3
val = a*r; 8 * 2 = 16
Print val; Prints 16
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 16; r = 2; counter = 4
val = a*r; 16 * 2 = 32
Print val; Prints 32
else { myMathFunction(val, r, counter + 1); }: True
The value of counter is incremented by 1 and the function gets the following values:
a= 32; r = 2; counter = 5
val = a*r; 32 * 2 = 64
Print val; Prints 64
if (counter > 4) { System.out.print("End"); } : True
This prints "End"
So; the output of the program is:
2 4 8 16 32 64 End
write a c program to insert and delete values from stack( to perform pop and push operations) using an array data structure
Answer:
How to implement a stack in C using an array?
A stack is a linear data structure that follows the Last in, First out principle (i.e. the last added elements are removed first).
This abstract data type can be implemented in C in multiple ways. One such way is by using an array.
Pro of using an array:
No extra memory required to store the pointers.
Con of using an array:
The size of the stack is pre-set so it cannot increase or decrease.
A list is sorted in ascending order if it is empty or each item except the last one is less than or equal to its successor.
a. True
b. False
