Answer:
Explanation:
1. Write a program that declares an array named alpha with 50 components of the type double. Initialize the array so that the first 25 components are equal to the square of the counter (or index) variable and the last 25 components are equal to three times the index variable.  
   double alpha[50];
    for (int i=0;i<25;i++)
    {
        alpha[i]=i*i;
        alpha[i+25]=(i+25)*3;
   }
2. Output the array so that exactly ten elements per line are printed.  
    for (int i=0;i<50;i++)
    {
        cout<<i+1<<". "<<alpha[i]<<" ";
        if (((i+1)%10)==0)
        {
            cout<<endl;
        }
    }
3. Run your program again, but this time change the code so that the array is filled with random numbers between 1 and 100.  
    double alpha[50];
    for (int i=0;i<50;i++)
    {
        alpha[i]=rand()%101;
    }
    for (int i=0;i<50;i++)
    {
        cout<<i+1<<". "<<alpha[i]<<" ";
        if (((i+1)%10)==0)
        {
            cout<<endl;
        }
    }
4. Write the code that computes and prints the average of elements of the array.  
    double alpha[50],temp=0;
    for (int i=0;i<50;i++)
    {
        alpha[i]=rand()%101;
        temp+=alpha[i];
    }
    cout<<"Average :"<<(temp/50);
5. Write the code that that prints out how many of the elements are EXACTLY equal to 100.
    double alpha[50],temp=0;
    for (int i=0;i<50;i++)
    {
        alpha[i]=rand()%101;
        if(alpha[i]==100)
        {
            temp++;
        }
    }
    cout<<"Elements Exacctly 100 :"<<temp;
Please note:  If you put  each of above code to the place below comment  it will run perfectly after compiling
#include <iostream>
using namespace std;
int main()
{
    // If you put  each of above code here it will run perfectly after compiling
    return 0;
}
 
        
             
        
        
        
Answer:
D. =AVERAGE(A1:A10)
Explanation:
The answer is D. 
With option A. It means the cell should contain the minimum figure in the range of cells <em>(A1:A10).</em>
With option B. It means the cell should contain the total sum of the figures in the range of cells <em>(A1:A10).</em>
With option C. It means the cell should contain the maximum figure of the range of cells <em>(A1:A10)</em>
 
        
             
        
        
        
<span>PING is a utility that can verify that TCP/IP is installed, bound to the NIC, configured correctly, and communicating with the network. Ping is used diagnostically to ensure that a host computer the user is trying to reach is actually operating. Ping works by sending an Internet Control Message Protocol (ICMP) Echo Request to a specified interface on the network and waiting for a reply. Ping can be used for troubleshooting to test connectivity and determine response time.</span>
        
             
        
        
        
Answer:
The code segment is written in Java.
-         boolean rsvp = true;
-         int selection;
-         String option1;
-         String option2;
- 
-         if(rsvp == true){
-             System.out.println("attending");
-         }else{
-             System.out.println("not attending");
-         }
Explanation:
Declare all the variables as required by the question (Line 1 - 4).
Create a control structure using if-else statements so that when rsvp equal to true, the program will display "attending" else it will display "not attending".
