The break statement can be used to eliminate the use of certain (flag) variables.

<h3>What is break statement?</h3>

A break statement is used to terminate the execution of the nearest enclosing for, do, switch, or while statement in which it appears.

The main purpose of break statement is to destroy the loop as soon as possible. For example if the given code asks a use input a integer number x. If x is divisible by 5, the break statement is executed and this causes the exit from the loop.

The advantage of break statement is it stops the case testing inside the block and break may be used within loops to alter control flow.

Therefore, the break statement can be used to eliminate the use of certain (flag) variables.

s2008m [1.1K]

Answer:

Network.

Explanation:

The Transmission Control Protocol/Internet Protocol (TCP/IP) model is a standard networking protocol which allows network devices such as routers, switches, and host computers to interconnect and communicate with one another over a network. The Transmission Control Protocol/Internet Protocol (TCP/IP) model comprises of four (4) layers and these includes;

I. Application layer.

II. Transport layer.

III. Internet layer.

IV. Network layer.

The network layer in the Transmission Control Protocol/Internet Protocol (TCP/IP) model is responsible for delivering data between two nodes.

Basically, this layer known as network layer is the fourth layer of the Transmission Control Protocol/Internet Protocol (TCP/IP) model and it is typically responsible for the transmission of packets from one network device to another.

erma4kov [3.2K]

To write a program that keeps names and email addresses in a dictionary as key-value pairs check the code given below.

<h3>What is key-value pairs?</h3>

In a key-value pair, two related data elements are combined: a value, which is a variable that belongs to the set (for example, male/female, green, 100), and a key, which is a constant that defines the data set (for example, gender, color, price).

A key-value pair could look something like this when fully formed:

gender = male

color = green

price > 100

↓↓↓//<u>Python code</u>//↓↓↓

import pickle

import sys

try:

f=open('email.dat','rb')

d=pickle.load(f)

f.close()

except:

d={}

while True:

print('\n1. Find a email address')

print('2. Add name and email address')

print('3. Change an email address')

print('4. Delete an email address')

print('5. Exit\n')

choice=input('\nEnter a choice: ')

if choice:

choice=int(choice)

else:

print('\nEnter a number')

continue

if choice == 1:

while True:

name=input('\nEnter the name ')

if name:

if name in d:

print('\n%s is the email id of %s \n' % (d[name],name))

break

else:

print('\n Email not found \n')

break

else:

print('\nName cannot be empty\n')

continue

elif choice==2:

while True:

if name:

break;

print('\nName cannot be empty \n')

continue

while True:

email=input('\nEnter the email address ')

if email:

break

else:
