Answer:

huh? Making your presentation more interesting through the use of multimedia can help to improve the audience's focus. PowerPoint allows you to use images, audio and video to have a greater visual impact. These visual and audio cues may also help a presenter be more improvisational and interactive with the audience.

t2=clock();

cout<<"Quick sort time and insertion sort time, with pivot median element:"<<(t2 - t1)*1000/ ( CLOCKS_PER_SEC );

return 0;

}

Explanation:

Change the value of n in the main file for different array size. Output is in the same format as mentioned, time is shown in milliseconds.

This loop is a good choice when you know how many times you want the loop to iterate in advance of entering the loop.1. do-while

Luba_88 [7]

Answer:

Option 3 is the correct answer.

Explanation:

In c, c++ or Java programming language, The for loop takes three parameters in which first is an initialization, second is condition check and the third is an increment. None of the other loop (except for loop) takes three parameters. The other loop takes only one parameter and that is the condition check.
So when a user knows about the times of iteration then it is a good choice to use the for loop but when the person does not know about the times of iteration if the loop. It means the iteration of the loop is based on the condition then it is a good choice to chose while or Do-while loop.
The above question wants to ask which loop for a user can best if he familiar with the iteration of the loop then the answer is for loop which is started from option 3. Hence Option 3 is the correct answer while the other is not because--

Option 1 states about the do-while loop which takes condition only.
Option 2 states about the while loop which also takes condition only.
Option 4 states about the infinite loop which is not any loop.
Option 5 states about none of these which is not correct because option 3 is the correct answer.

To format an individual sparkline, select the sparkline you want to format, and then click the Ungroup button in the Group group

vichka [17]

Answer:

The answer is "Option a"

Explanation:

A Sparkline is a small graph, which is available inside a sheet, that displays information visually. It displays the information is in the form of patterns on several values. It also uses underline to display the low and high value, use with sparklines, and certain alternatives were wrong, which can be defined as follows:

In option b, It is used to define the overall view of data, that's why it is wrong.
Option c and Option d both are wrong because, create command is used to create data, or view is used to show that data, they both don't use sparkline option.
