ddd [48]

The statement 'an embedded system describes computing technology that has been enclosed in protective shielding for security reasons is false.

In the field of computers and technology, an embedded system can be described as a small computer, more overly an integrated chip, that is enclosed in an electronic device in order for making the device to run. The small computer integrated into the device helps in regulating the device. The purpose of an embedded system is not for protective shielding or security reasons hence the statement above is false.

In an embedded system, a combination of computer processor, computer memory, and input/output peripheral devices is present that performs a dedicated function. Microcontrollers are used for the management of an embedded system.

Write a program that reads two fractions such as 1/2 and 1/4 and computes and stores the sum, the difference, the product and th

Vesnalui [34]

Answer:

1: #include <iostream>

2: using namespace std;

3: int main()

4: {

5: int a,b,c,d;

6: cout<<"n1: ";

7: cin>>a;

8: cout<<"d1: ";

9: cin>>b;

10: cout<<"n2: ";

11: cin>>c;

12: cout<<"d2: ";

13: cin>>d;

14: int top = (a*d)+(b*c);

15: int bottom = b*d;

16: cout<<"Sum: "<<top<<"/"<<bottom<<"\n";

17: top = (a*d)-(b*c);

18: cout<<"Difference: "<<top<<"/"<<bottom<<"\n";

19: top = a*c;

20: cout<<"Product: "<<top<<"/"<<bottom<<"\n";

21: top = a*d;

22: bottom = b*c;

23: cout<<"Quotient: "<<top<<"/"<<bottom<<"\n";

24: return 0;

25: }

Explanation:

The Program is written in C++ programming language

The Program is left numbered

Line 5 was used for variable declaration.

Variables a,b represents the numerator and denominator of the first fraction

While variables c,d represent the numerator and denominator of the second fraction

Line 6 prints "n1" without the quotes which represents the numerator of the first fraction

Line 7 accepts input for the numerator of the first fraction.

Line 8 prints "d1" without the quotes which represents the denominator of the first fraction

Line 9 accepts input for the denominator of the first fraction.

Line 10 prints "n2" without the quotes which represents the numerator of the second fraction

Line 11 accepts input for the numerator of the second fraction.

Line 12 prints "d2" without the quotes which represents the denominator of the second fraction

Line 13 accepts input for the denominator of the second fraction.

Line 14 and 15 calculate the sum of the fractions which is then printed on line 16

Line 17 calculates the difference of the fractions which is then printed on line 18

Line 19 calculates the product of the fractions which is then printed on line 20

Line 21 and 22 calculates the quotient of the fractions which is then printed on line 23

True or false An electronic form uses input fields in which the user can enter data from their own computer and then transmit t

miskamm [114]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

An electronic form uses input fields in which the user can enter data from their own computer and then transmit the form back to the company - (True)

Yes, it is true, because an electronic form that contains input fields which is used to collect data from the user. The input fields in the electronic form are based on the requirement of the organization about what they want to collect from their user.

For example, when you signup on google account, google company wants to know about your authentication. So the user enters the data in input fields such as first name, last name, phone number etc. When the user clicks on the submit or signup button, all these input values are then transmitted back to the company (google).

This is your chance to become the instructor. After learning the looping and input validation concepts, create a problem to give

enot [183]

Answer:

See Explaination

Explanation:

The Problem information is as follows:

The input: A data file containing the bank account information.Accounts are of different

types (like Savings Account, Checking Accounts).

The Output: Report on Number of Savings Account, Number of Checking accounts and their

total balances, avregae balance, maximum and minimum balance etc

Processing:

Read the file data

Consider valid account data

Separate different accounts

Calculate the sum of their balances

Calculate the average balnace for each type of account

Display the information

Solution:

1.The application should be able to read the csv file.

2.All the error checking should be done as per defined rules

3.The report should be generated in the defined format

4.Data display precisions need to be followed.

5.Interactive errors should be reported with proper messages

6.Integrity of the data should be maintaied while saving the data.

7. Calculation of the averageAccountBalance = (Sum of all the balances of a particular type of account)/(number of that type of account)

8. TotalAccountBalance = Sum of all the balances of each type of account.

9. To find maximum start with a default value and then traverse all the accounts and update the maximum value as per the comparison results

and same for minimum.

Input Validation:

1.Check for the filename (maximum length is 10 chars besides the csv extension)

2.account number (12 digits, first three entries are alphabets)

3.Name (Only alphabets are allowed)

4.Phone Number (7 digits must follow the format xxx-xxx-x)

pesudoCode:

Input filename

open the file

declare accounts[] array

Read the data in accounts and update numOfAccounts

declare numOfAccounts, numOfSavingActs, numOfCheckingActs, totalBalanceSavings, totalBalanceChecking, averageBalanceChecking

averageBalanceSavings, maximumSaavings, minimumSavings, maximumChecking, minimumChecking

for i = 1 to n:

if (Validate(account[i])):

if account[i].type == "Savings":

numOfSavingActs++

totalBalanceSavings = totalBalanceSavings + account[i].balance

if account[i].balance > maximumSavings:

maximumSavings = account[i].balance

if account[i].balance < minimumSavings:

minimumSavings = account[i].balance

if account[i].type == "Checkings":

numOfSavingActs++

totalBalanceSavings = totalBalanceSavings + account[i].balance

if account[i].balance > maximumSavings:

maximumSavings = account[i].balance

if account[i].balance < minimumSavings:

minimumSavings = account[i].balance
