Answer 1
Answer:

Answer: (A) Prepared statement

Explanation:

 Prepared statement is basically used in the structured query language (SQL) statement which are basically execute multiple times in the python script.

The prepared statement is typically used in the SQL statement for update and queries. It is used to executed for the similar SQL statement and it has high efficiency.

It basically is in the form of template where the database compile and perform various query optimization.

A mobile device user is having problems launching apps and texting. The user touches an app to launch it, but the app icon next to the desired app launches instead. When the user types a text message, every word in the message is misspelled. What is the most likely cause for this behavior?
The program that you create for this exercise will begin by reading the cost of a meal ordered at a restaurant from the user. Then your program will compute the tax and tip for the meal. Use your local tax rate when computing the amount of tax owing. Compute the tip as 18 percent of the meal amount (without the tax). The output from your program should include the tax amount, the tip amount, and the grand total for the meal including both the tax and the tip. Format the output so that all of the values are displayed using two decimal places.

Which of the following function declarations correctly expect an array as the first argument?Question 1 options:

void f1(int array, int size);

void f1(int& array, int size);

void f1(int array[100], int size);

void f1(float array[], int size);

All of the above

C and D

A and B

Answers

Answer:

Only

Option: void f1(float array[], int size);

is valid.

Explanation:

To pass an array as argument in a function, the syntax should be as follows:

functionName (type arrayName[ ] )

We can't place the size of the array inside the array bracket (arrayName[100]) as this will give a syntax error. The empty bracket [] is required to tell the program that the value that passed as the argument is an array and differentiate it from other type of value.

PLEASE HELP!!!For this activity, you will create two designs for the same project. For example, you might choose to create a CD cover for your favorite band’s newest release, or you might want to design a menu for the local deli. No matter what you decide for your subject matter, the two designs must involve different media. One of these media will be an image-editing program, such as Inkscape. You will learn more about the basic tools available in Inkscape later in this lesson. The two designs should incorporate different techniques. For example, you might make one design abstract, while making the other more realistic. Be sure to save both of your designs. Scan or take a picture of the design that wasn’t created in an image-editing program. You will submit this item later in this lesson as your portfolio item.

I'm not exactly sure on what the question is, but from reading it, I determined that you'll be creating 2 different designs using Inkscape/Photoshop. I'm leaving 2 of my designs in here for you to use on your project. Unknown on what to do about the design that wasn't created in an image-editing program.

Suppose that each country completely specializes in the production of the good in which it has a comparative advantage, producing only that good. Inthis case, the country that produces rye will produce million bushels per week, and the country that produces jeans will produce

million pairs per week.

Answers

Answer:

In  this case, the country that produces rye will produce 24 million bushels per week, and the country that produces jeans will produce 64  million pairs per week.

Explanation:

Total labor hour = 4 million hour

Number of bushes produce in 1 hour = 6

⇒total bushes produce = 6*4 = 24 million

∴ we get

The country that produces rye will produce 24 million bushels per week

Now,

Total labor hour = 4 million hour

Number of pairs produce in 1 hour = 16

⇒total bushes produce = 16*4 = 64 million

∴ we get

The country that produces jeans will produce 64  million pairs per week.

One author states that Web-based software is more likely to take advantage of social networking (Web 2.0) approaches such as wikis and blogs. If this is the case, can we expect more social networking capabilities in all future software? Aside from LinkedIn, how can social media be leveraged by CIT graduates?

Answers

Answer:

Yes

Explanation:

I will say Yes. There are very much limitless possible and future we can expect from social media and even more from social networking. Its capabilities from upcoming software in the future. Since the Internet is in its early days of growing and cloud computing being introduced there are way more possibilities in the future.

Social media can be duely applied by CIT (Computer Information Technologies) graduates. It can be used to improve them in their career and also will helps them connect professionally. Quora is one such platform which is not exactly like LinkedIn but pretty much serves the purpose.
