Answer:

x=arr[arr.length-2]; is the correct answer for the given question.  

Explanation:

In the above statement firstly we calculate the length of the given array.The arr.length function is used to calculate the array length.As mention in the question we have to assign the next to last element of the array to the variable x, so we used arr[arr.length-2] and finally, we assign them to the variable x.

so the final statement is x=arr[arr.length-2];

Write a C++ program to count even and odd numbers in array. The array size is 50. The array elements will be entered by the user
vlabodo [156]

Answer:

The program in C++ is as follows:

#include <iostream>

using namespace std;

int main(){

   int numbers[50];

   int evekount = 0, odkount = 0;

   for(int i = 0; i<50;i++){

       cin>>numbers[i];

       if(numbers[i]%2==0){            evekount++;        }

       else{            odkount++;        }

   }

   cout<<"Even Count: "<<evekount<<endl;

   cout<<"Odd Count: "<<odkount<<endl;

   return 0;

}

Explanation:

This declares the integer array of number

   int numbers[50];

This initializes the even count and odd count to 0

   int evekount = 0, odkount = 0;

This iterates from 1 to 50

   for(int i = 0; i<50;i++){

This gets input for the array

       cin>>numbers[i];

This checks for even

<em>        if(numbers[i]%2==0){            evekount++;        }</em>

This checks for odd

<em>        else{            odkount++;        }</em>

   }

This prints the even count

   cout<<"Even Count: "<<evekount<<endl;

This prints the odd count

   cout<<"Odd Count: "<<odkount<<endl;

You plug a new scanner into a USB port on your Windows system. When you first turn on the scanner, what should you expect to see
Paul [167]

Answer:

A window notifying that: Found New Hardware Wizard

Explanation:

As soon as any device is plugged into the USB port, the default settings will display a window onto the screen which will notify about the addition of a new hardware to the system. This window can further be used to know the properties of the hardware or for configuration settings.

This process is same like the software part, that whenever a new application is installed onto the system a pop up notification alerts about its presence.

So when the scanner will be attached through USB port a window will be appeared notifying about the discovery of new hardware.
