Answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

   // variables

int n;

double average,sum=0,x;

cout<<"enter the Value of N:";

// read the value of N

cin>>n;

cout<<"enter "<<n<<" Numbers:";

// read n Numbers

for(int a=0;a<n;a++)

{

   cin>>x;

   // calculate total sum of all numbers

   sum=sum+x;

}

// calculate average

average=sum/n;

// print average

cout<<"average of "<<n<<" Numbers is: "<<average<<endl;

return 0;

}

Explanation:

Read the total number from user i.e "n".Then read "n" numbers from user with for loop and sum them all.Find there average by dividing the sum with n.And print the average.

Output:

enter the Value of N:5

enter 5 Numbers:20.5 19.7 21.3 18.6 22.1

average of 5 Numbers is: 20.44

Network a0 is a process by which several protocols evolve to form a single product.
mafiozo [28]

Answer:

Convergent network

Explanation:

In networking, computers devices are connected together to communicate and share resources. Devices like routers and switches are examples of intermediate network devices and computers, smartphones, tablets and IP phones are all examples of end devices in a network.

In the past, dedicated networks are installed for separate voice, text and video packets. But as information technology evolves, one network is used for all three packets. This network is called convergent network.

9.10: Reverse ArrayWrite a function that accepts an int array and the array ’s size as arguments . The function should create a
AleksandrR [38]

Answer:

#include <iostream>

using namespace std;

int * reverse(int a[],int n)//function to reverse the array.

{

   int i;

   for(i=0;i<n/2;i++)

   {

       int temp=a[i];

       a[i]=a[n-i-1];

       a[n-i-1]=temp;

   }

   return a;//return pointer to the array.

}

int main() {

   int array[50],* arr,N;//declaring three variables.

   cin>>N;//taking input of size..

   if(N>50||N<0)//if size greater than 50 or less than 0 then terminating the program..

   return 0;

   for(int i=0;i<N;i++)

   {

       cin>>array[i];//prompting array elements..

   }

   arr=reverse(array,N);//function call.

   for(int i=0;i<N;i++)

   cout<<arr[i]<<endl;//printing reversed array..

   cout<<endl;

return 0;

}

Output:-

5

4 5 6 7 8

8

7

6

5

4

Explanation:

I have created a function reverse which reverses the array and returns pointer to an array.I have also considered edge cases where the function terminates if the value of the N(size) is greater than 50 or less than 0.

Suppose for the worst case, given input size n: Algorithm 1 performs f(n) = n2 + n/2 steps Algorithm 2 performs f(n) = 12n + 500
melomori [17]

Answer:

29

Explanation:

for n=28:

--------------

Algorithm 1 performs f(n) = n2 + n/2 = 28*28 + 28/2 = 798

Algorithm 2 performs f(n) = 12*28 + 500 = 836

for n=29

--------------

Algorithm 1 performs f(n) = n2 + n/2 = 29*29 + 29/2 = 855.5

Algorithm 2 performs f(n) = 12*29 + 500 = 848

so, for n=29, algorithm 2 will be faster than algorithm 1
