Answer:

Cloud database eliminates the need for establishing and maintaining data centres.

Explanation:

Cloud computing provides an organisation with the infrastructure they need but can not afford. A large online storage with access control policies is available based to subscription.

For a company to establish a data centre, they would need a team of skilled network engineers, fleet of high speed server systems and large storage devices.

The daily power supply and management, coupled with the needed skills and items, can be overwhelming for a company whose main objective is not to deliver database services. So cloud computing is adopted to reduce the cost.

Taya2010 [7]

Answer:

// program in C++ to check leap year.

// include header

#include<iostream>

using namespace std;

// main function

int main() {

// variable

int inp_year ;

// ask user to enter year

cout<<"Enter year:";

// read year

cin>>inp_year;

// check year is leap or not

if (((inp_year % 4 == 0) && (inp_year % 100 != 0)) || (inp_year % 400 == 0))

// if leap year , print leap year

cout<<inp_year<<" is a leap year.";

else

// print not leap year

cout<<inp_year<<" is not a leap year.";

return 0;

}

Explanation:

Read year from user.Then check if year is divisible by 4 and not divisible by 100 or year is divisible by 400 then year is leap year.otherwise year is not leap year.

Output:

Enter year:1712

1712 is a leap year.

You would like the user of a program to enter a customer’s last name. Write a statement thaUse the variables k, d, and s so that

mojhsa [17]

Answer:

1st question:

Use the variables k, d, and s so that they can read three different values from standard input an integer, a float, and a string respectively. On one line, print these variables in reverse order with exactly one space in between each. On a second line, print them in the original order with one space in between them.

Solution:

In Python:

k = input() #prompts user to input value of k i.e. integer value

d = input() #prompts user to input value of d i.e. float value

s = input() #prompts user to input value of s i.e. a string

print (s, d, k) #displays these variable values in reverse order

print (k, d, s)#displays these variable values in original order

In C++:

#include <iostream> // to use input output functions

using namespace std; //to identify objects like cin cout

int main() { //start of main function

int k; //declare int type variable to store an integer value

float d; // declare float type variable to store a float value

string s; // declare string type variable to store an integer value

cin >> k >> d >> s; //reads the value of k, d and s

cout << s << " " << d << " " << k << endl; //displays these variables values in reverse order

cout << k << " " << d << " " << s << endl; } // displays these variable values in original order

Explanation:

2nd question:

You would like the user of a program to enter a customer’s last name. Write a statement that asks user "Last Name:" and assigns input to a string variable called last_name.

Solution:

In Python:

last_name = input("Last Name:")

# input function is used to accept input from user and assign the input value to last_name variable

In C++:

string last_name; //declares a string type variable named last_name

cout<<"Last Name: "; // prompts user to enter last name by displaying this message Last Name:

cin>>last_name; // reads and assigns the input value to string variable last_name

The programs alongwith their outputs are attached.

lapo4ka [179]

Answer:

The answer to this question is given below in the explanation section. It is noted that this program is written in C++ using online C++ compiler.

Explanation:

#include <iostream>

using namespace std;

int squared(int num)// this is the function to compute square

{

return num*num;

}

int cube(int num)// this is the function to compute cube

{

return num*num*num;

}

int main()

{

int user_num, user_num2; // variable declaration

cout<<"Enter the first number: ";//prompt user to enter the number

cin>>user_num;//store the user entered number into variable

cout<<"\nEnter the second number: ";//prompt the user to enter the second number

cin>>user_num2;//store the user entered number into variable

cout<<"\nSquared of first number is: "<<squared(user_num);//compute square of user_num and display

cout<<"\nCube of first number is: "<<cube(user_num);//compute the cube of the user_num and display

cout<<"\nSquare of second number is: "<<squared(user_num2);//compute the square of user_num2 and display

cout<<"\nCube of second number is: "<<cube(user_num2);//compute the cube of user_num2 and display

cout<<"\nSum of number 1 and number 2 is: "<<user_num2 + user_num2;//display the sum of user_num2 and user_num

cout<<"\nProduct of number 1 and number 2 is: "<<user_num2 * user_num;//display the product of user_num and user_num2

return 0;//terminate the program
