return 0;
}
/*The function fileSum that takes the string filename and
count the sum of the values and returns the sum of the values*/
int fileSum(string filename)
{
//Create a ifstream object
ifstream fin;
//Open a file

//Initialize sum to zero
int sum=0;
//Check if file exist
if(!fin)
{
cout<<"File does not exist ."<<endl;

exit(1);
}
else
{
int value;

Answer:
You should now be able to give IP addresses to 254 hosts. This works fine if all 150 computers are on a single network. However, your 150 computers are on three separate physical networks. Instead of requesting more address blocks for each network, you divide your network into subnets that enable you to use one block of addresses on multiple physical networks

Answer:
Option C: Windows Virtual PC is the correct answer.
Explanation:
The virtualization program for Microsoft Windows is given by Windows Virtual PC. As discussed it has an AMD processor installed that includes AMD-V technology and the motherboard fully supports this processor.
The superseded version of Windows virtual PC is Hyper-V. It is the most capable version of Microsoft hypervisor you can install on this machine, provided the computer meets all the other requirements.
All other options are wrong as the virtualbox is not considered as the Microsoft hypervisor therefore can't be installed. Similarily, the hypervisor named as Windows XP mode is not so capable that it could meet all requirements. In the end, the Parallel Desktops can not be run on the machines as they dont come under the Microsoft hypervisor category.
I hope it will help you!
Answer:
return values.remove() + values.remove();
Explanation:
The appropriate expression to complete the method, which is designed to return the sum of the two smallest values in the parameter array number is indicated below in bold font :
public static int
sumTwoLowestElements(int[] numbers)
{
PriorityQueue values = new PriorityQueue<>();
for (int num: numbers)
{ values.add(num);
}
return values.remove() + values.remove();
}
The return statementin programming is often used when a function is ready to return a value to its caller.
