Consider the following incomplete code segment, which is intended to print the sum of the digits in num. For example, when num is 12345, the code segment should print 15, which represents the sum 1 + 2 + 3 + 4 + 5. int num = 12345;int sum = 0;/ missing loop header /{sum += num % 10;num /= 10;}System.out.println(sum);Which of the following should replace / missing loop header / so that the code segment will work as intended?

Answers

The term  that should replace / missing loop header / so that the code segment will work as intended is option A: while (num > 0).

What is the header about?

The body of the code is executed once for each iteration, and the header specifies the iteration.

The body of a for loop, which is executed once each iteration, and the header, which specifies the iteration, are both components. A loop counter or loop variable is frequently declared explicitly in the header.

Therefore, the module and division action inside the loop must be our main attention in order to comprehend why. The crucial thing to remember is that we are adding the numbers in reverse order and that we must repeat this process until we reach the initial number (1%10 = 1). As a result, num must equal one in order to compute the final operation.

you have a 10vdg source available design a voltage divider ciruit that has 2 vdc , 5vdc , and 8 vdc available the total circuit current is to be 2mA

Answers

If you try to divide 10V in three voltages, the sum of the three voltages must be equal to the total voltage source, in this case 10V. Having said this, 2 + 5 + 8 = 15V, and your source is only 10V. So you can see is not feasible. You can, for example, have 2V, 5V and 3V, and the sum is equal to 10V. Before designing the circuit, i.e, choosing the resistors, you need to understand this. Otherwise, I suggest you to review the voltage divider theory.

For instance, see IMG2 in my previous post. If we were to design a single voltage divider for the 5VDC, i.e, 50% of the 10V source, you generally choose R1 = R2., and that would be the design equation.

Work out Alberta's husband's first and last name, as well as Carla's, Paula's, and Roberta's husbands' first and last name

Answers

The couples, considering the patterns in the problem, are listed as follows:

Carla and Robert Paulson.Paula and Albert Robertson.Alberta and Paul Carlson.Roberta and Carl Albertson.

What are the couples?

We use the information from the bullet points to find the couples.

The first information is:

No woman's husband has a first name that consists of her first name without the final "a".

Hence:

Alberta is married to either Carl, Paul or Robert.Carla is married to either Albert, Paul or Robert.Paula is married to either Albert, Carl or Robert.Roberta is married to either Albert, Carl or Paul.

The second information is:

Paul is not married to Roberta, and Robert is not married to Paula.

Hence:

Roberta is married to either Albert or Carl.Paula is married to either Albert or Carl.

No husband and wife have "bert" in both their first names, hence:

Roberta is married to Carl.Paula is married to Albert.Alberta is married to Paul.Carla is married to Robert.

No woman's last name consists of her first name without the final "a" and with "son" on the end, and no man's last name consists of his first name with "son" added at the end, hence:

Roberta and Carl are either Albertson or Paulson.Paula and Albert are either Carlson or Robertson.Alberta and Paul are either Carlson or Robertson.Carla and Robert are either Albertson or Paulson.

There is a man who has "bert" in his first and last names, hence either of these two can be couples.

Carla and Robert Albertson.Paula and Albert Robertson.

Carl's last name is not Paulson, hence a couple is:

Carla and Robert Paulson.

Then Carla and Robert are Paulson, and the couples are:

Carla and Robert Paulson.Paula and Albert Robertson.Alberta and Paul Carlson.Roberta and Carl Albertson.

Answers

The most appropriate change in this situation would be to change the message "User input deemed invalid" to "You made a mistake, try again, you can".

What should we change to improve the children's experience?

To improve children's experience with this new calculator program, we must adapt all the features of the program for children's users. Therefore, the buttons, the messages and everything related to this program must be suitable for their motor and brain development.

Therefore, it is considered that the message "User input deemed invalid" is not suitable for children because they may not understand this message or misinterpret it and desist from using the new program.

So, the most appropriate message to replace the previous message would be:

_________ is a variety of mechanisms used to assure the integrity of a data unit or stream of data units.

Answers

Answer:

Data integrity.

Explanation:

Data integrity is a variety of mechanisms used to assure the integrity of a data unit or stream of data units.

In Computer programming, integrity constraints can be defined as a set of standard rules that ensures quality information and database are maintained.

Basically, there are four (4) types of integrity constraints and these are;

1. Key constraints.

2. Domain constraints.

3. Entity integrity constraints.

4. Referential integrity constraints.

For example, when a foreign key in Table A points to the primary key of Table B, according to the referential integrity constraints, all the value of the foreign key in Table A must be null or match the primary key in Table B.

Hence, any integrity constraint ensures that the relationship between the data in a table is consistent and valid.
