Use the variables k, d, and s so that they can read three different values from standard input--an integer, a double, and a stri

Nat2105 [25]

Answer:

The c++ program to implement the given scenario is shown below.

#include <iostream>

using namespace std;

int main() {

// variables declared as mentioned

int k;

double d;

string s;

cout << " Enter an integer value, a double value, a string value in the mentioned order " << endl;

cin >> k >> d >> s;

// variables printed in reverse order

cout << " Reverse order " << endl;

cout << s << " " << d << " " << k << endl;

// variables printed in original order

cout << " Original order " << endl;

cout << k << " " << d << " " << s << endl;

return 0;

}

OUTPUT

Enter an integer value, a double value, a string value in the mentioned order

12 45.67 brainly

Reverse order

brainly 45.67 12

Original order

12 45.67 brainly

Explanation:

1. All the variables are declared as mentioned in the question.

int k;

double d;

string s;

2. The user is prompted to enter values for integer, double and string variables respectively. The input is accepted in the order mentioned above.

cin >> k >> d >> s;

3. The input is accepted in a single line since this is mentioned in the scenario that variables should be printed in the order in which they are read.

4. These variables are displayed to the standard output in reverse order – string, double, integer. The variables are displayed with exactly one space in between them.

cout << s << " " << d << " " << k << endl;

5. Then, variables are displayed in the original order – integer, double, string. The variables are displayed with exactly one space in between them.

cout << k << " " << d << " " << s << endl;

Which statement about broadcasting a slideshow online is true?

9966 [12]

Answer: PowerPoint has a free, built-in service for broadcasting online.

Explanation:

The statement that's true about the broadcast of a slideshow online is that PowerPoint has a free, built-in service for broadcasting online.

Option 1 is wrong as all transitions are not properly displayed to the audience when broadcasting online.

Option 2 is wrong as broadcasting as slideshow online is an option for most PowerPoint users.

Option 3 is wrong because when broadcasting online, third party desktop sharing software isn't necessarily an option and it isn't a must that it must be used.

Therefore, the correct option is 4.

Find the propagation delay for a signal traversing the in a metropolitan area through 200 km, at the speed of light in cable (2.

Ede4ka [16]

Answer:

t= 8.7*10⁻⁴ sec.

Explanation:

If the signal were able to traverse this distance at an infinite speed, the propagation delay would be zero.

As this is not possible, (the maximum speed of interactions in the universe is equal to the speed of light), there will be a finite propagation delay.

Assuming that the signal propagates at a constant speed, which is equal to 2.3*10⁸ m/s (due to the characteristics of the cable, it is not the same as if it were propagating in vaccum, at 3.0*10⁸ m/s), the time taken to the signal to traverse the 200 km, which is equal to the propagation delay, can be found applying the average velocity definition:

$v = \frac{(xf-xo)}{(t-to)}$

If we choose x₀ = 0 and t₀ =0, and replace v= 2.3*10⁸ m/s, and xf=2*10⁵ m, we can solve for t:

$t =\frac{xf}{v} =\frac{2e5 m}{2.3e8 m/s} =8.7e-4 sec.$

⇒ t = 8.7*10⁻⁴ sec.
