Answer:
#include <iostream>
using namespace std;
int main() {
int k;
double d;
string s;
cin >> k >> d >> s;
cout << s << " " << d << " " << k << "\n" << k << " " << d << " " << s; }
Explanation:
k is int type variable that stores integer values.
d is double type variable that stores real number.
s is string type variable that stores word.
cin statement is used to take input from user. cin takes an integer, a real number and a word from user. The user first enters an integer value, then a real number and then a small word as input.
cout statement is used to display the output on the screen. cout displays the value of k, d and s which entered by user.
First the values of k, d and s are displayed in reverse order. This means the word is displayed first, then the real number and then the integer separated again by EXACTLY one space from each other. " " used to represent a single space.
Then next line \n is used to produce a new line.
So in the next line values of k, d and s are displayed in original order (the integer , the real, and the word), separated again by EXACTLY one space from each other.
The program along with the output is attached.
Explanation: It's something like siri. It's a machine or technology inside a phone or computer that gives you information to a question that you asked.
Answer:
<em>The programming language is not stated;</em>
<em>However, the program written in Python is as follows</em>
def solveEquation(x,y,z):
result = z - y + 2 * x
print(result)
x = float(input("x = "))
y = float(input("y = "))
z = float(input("z = "))
print(solveEquation(x,y,z))
Explanation:
This line defines the function solveEquation
def solveEquation(x,y,z):
This line calculates the expression in the question
result = z - y + 2 * x
This line returns the result of the above expression
print(result)
The next three lines prompts user for x, y and z
x = float(input("x = "))
y = float(input("y = "))
z = float(input("z = "))
This line prints the result of the expression
print(solveEquation(x,y,z))
Answer:
The web browser sends an HTTP request to the IP address, the IP address then sends the content that are displayed by the browser
Explanation:
The process of converting the typed in URL to a displayed page is as follows;
1) The typed in URL is sent to a DNS recursor by the browser
2) The recursor gets the DNS record for the domain from the cache if the record is cached or when the DNS record for the domain is not cached, the recursor makes a requests to the DNS root from which the name of the TLD nameserver is received
3) The TLD nameserver is contacted by the resolver to obtain the authoritative nameserver's IP address
4) With the information, the resolver contacts the authoritative nameserver and obtains the domain's IP address for the domain the resolver contacts
5) The obtained IP address for the URL's domain is then sent to the browser by the resolver
6) An HTTP request is sent by the browser to the IP address and the data received by the browser from that IP address is rendered and seen as the page content.
