Consider the following code segment, which is intended to simulate a random process. The code is intended to set the value of the variable event to exactly one of the values 1, 2, or 3, depending on the probability of an event occurring. The value of event should be set to 1 if the probability is 70 percent or less. The value of event should be set to 2 if the probability is greater than 70 percent but no more than 80 percent. The value of event should be set to 3 if the probability is greater than 80 percent. The variable randomNumber is used to simulate the probability of the event occurring.
int event = 0;
if (randomNumber <= 0.70)
{
event = 1;
}
if (randomNumber <= 0.80)
{
event = 2;
}
else
{
event = 3;
}
The code does not work as intended. Assume that the variable randomNumber has been properly declared and initialized. Which of the following initializations for randomNumber will demonstrate that the code segment will not work as intended?
A) randomNumber = 0.70;
B) randomNumber = 0.80;
C) randomNumber = 0.85;
D) randomNumber = 0.90;
E) randomNumber = 1.00;

Answers

Answer:

A) randomNumber = 0.70;

Explanation:

The code works perfectly for all values of randomNumber given in the options except option (a)

This is so because:

The first condition

if (randomNumber <= 0.70)  {  event = 1;  }

It checks if randomNumber is less than or equal to 0.70. This is true, so event is set to 1.

However, the next condition after it will also be executed because it is a different conditional to be executed.

So, we have:

if (randomNumber <= 0.80)  {  event = 2;  }

This condition is also true, so event is set to 2.

From the question randomNumber is meant to be event 1. However, this is different from the result of executing the code.

Hence, (a) is true

Why is hydroelectricity counted as a conventional source of energy.. People say conventional sources of energy is the same as non-renewable energy sources

Answers

People have been using the energy of flowing or falling water for centuries before electricity was developed into a practical means of transporting energy. The first hydroelectric plant (at least in the U.S.) was built at Niagara Falls in 1895. Many areas of the world still get the majority of their power from hydro facilities.

Hydro is also “conventional” in the sense that it can be controlled in more or less the same way as thermal plants — its output can be adjusted over a wide range to match demand. Wind and solar, on the other hand, only produce when the wind blows or the sun shines. Of course, hydro can only produce as long as there’s rain or snowmelt to supply the reservoirs, but that’s on a much longer time scale; over hours or days, hydro capacity is very predictable.

Under the Gramm-Leach-Bliley-Act (GLBA), banks must protect customer privacy. A given bank has just implemented its online banking solution that allows customers to access their accounts and perform transactions via their computers or personal digital assistant (PDA) devices. Online banking servers and their public Internet hosting would fall within which domains of security responsibility?

Answers

Answer:

System/Application Domain and LAN-to-WAN Domain.

Explanation:

The Gramm-Leach-Bliley-Act is also referred to as the Financial Services Modernization Act of 1999. It was enacted by the 106th Congress of the United States of America and it requires that financial institutions explain to their customers the information sharing policies and ensure that customer sensitive data (privacy) is safeguarded.

This, under the Gramm-Leach-Bliley-Act (GLBA), banks must protect customer privacy.

In this scenario, a given bank has just implemented its online banking solution that allows customers to access their accounts and perform transactions via their computers or personal digital assistant (PDA) devices.

Hence, online banking servers and their public Internet hosting would fall within the System/Application Domain and LAN-to-WAN Domain.

In an IT infrastructure, there are seven main domains and these are the: User Domain, Workstation Domain, LAN Domain, LAN-to-WAN Domain, Remote Access Domain, WAN Domain, and System/Application.

8.11 LAB: Contact list (C++)









A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name.


Ex: If the input is:


3 Joe 123-5432 Linda 983-4123 Frank 867-5309

Frank

the output is:


867-5309


Your program must define and call the following function. The return value of GetPhoneNumber is the phone number associated with the specific contact name.

string GetPhoneNumber(vector nameVec, vector phoneNumberVec, string contactName)


Hint: Use two vectors: One for the string names, and the other for the string phone numbers.
