Answer:

Jason = 20yrs.old

Mandy = 15yrs.old

Explanation:

Let

J = Jason's age

M = Mandy's age

J+M=35 ..... eq. 1

J−10=2(M−10) ..... eq. 2

From eq. 1

J=35−M

Substitute this in eq. 2.

(35−M)−10=2(M−10)

35−10−M=2M−20

35−10+20=2M+M

45=3M

453=3M3

15=M

J=35−M

J=35−15

J=20

An identifier that is prefixed with an @ and allows you to use code written in other languages that do not have the same set of

Nina [5.8K]

Answer:

Verbatim Identifier

Explanation:

Verbatim Identifier contains @ symbol as a prefix by which enables you to use reserved words of a programming language as identifier. For example the keywords like int, double, goto, char, else, while, for, float etc can be used as strings or variable names if @ symbol is added before these words e.g. @char, @while, @void, @int etc.
The compiler of a language will recognize such identifiers as verbatim identifiers and compiles them without giving an error that these are reserved words.
Verbatim identifier is used for program that is written in other languages and those languages don't have same reserved words.
For example: cout<<"use of verbatim identifier";<<@for; In this statement, for keyword which is used in for loop can be used as an identifier with @ in the prefix.
The escape sequences if used with @ symbol in prefix then they are interpreted in a different way. For example in C#

string a = "\\C:\torrent\new\file";

Console.WriteLine(a);

This statement will give the following output:

\C: orrent

ewfile

This means that the \t in the start of torrent and \n in the start of new word is taken as an escape sequence and output displayed is giving tab space because of \t and prints the rest of the words in new line because of \n escape sequence.

Now lets use this with the @ symbol

string a = @"\\C:\torrent\new\file";

Console.WriteLine(a);

The output will now be:

\\C:\torrent\new\file

\t and \n are not taken as escape sequences by the compiler because of @ symbol.

Write a program that creates a dictionary containing the U.S. states as keys and their abbreviations as values. The program shou

AleksandrR [38]

Answer:

Explanation:

The following program is written in Python. It creates a loop that keeps creating a random number to randomly choose a State abbreviation from the dictionary. Then it asks the user what the state is. If the user gets the answer correct it prints out "Correct" and adds 1 point to the correct variables. Otherwise it prints "Incorrect" and adds 1 point to the incorrect variable. Finally, printing out the final amount of correct and incorrect responses. The program was tested and the output can be seen below.

import random

states = {"AL":"Alabama","AK":"Alaska","AZ":"Arizona","AR":"Arkansas","CA":"California","CO":"Colorado","CT":"Connecticut","DE":"Delaware","FL":"Florida","GA":"Georgia","HI":"Hawaii","ID":"Idaho","IL":"Illinois","IN":"Indiana","IA":"Iowa","KS":"Kansas","KY":"Kentucky","LA":"Louisiana","ME":"Maine","MD":"Maryland","MA":"Massachusetts","MI":"Michigan","MN":"Minnesota","MS":"Mississippi","MO":"Missouri","MT":"Montana","NE":"Nebraska","NV":"Nevada","NH":"New Hampshire","NJ":"New Jersey","NM":"New Mexico","NY":"New York","NC":"North Carolina","ND":"North Dakota","OH":"Ohio","OK":"Oklahoma","OR":"Oregon","PA":"Pennsylvania","RI":"Rhode Island","SC":"South Carolina","SD":"South Dakota","TN":"Tennessee","TX":"Texas","UT":"Utah","VT":"Vermont","VA":"Virginia","WA":"Washington","WV":"West Virginia","WI":"Wisconsin","WY":"Wyoming"}

keys_list = list(states)

correct = 0

incorrect = 0

while True:

randNum = random.randint(0, 49)

abbr = keys_list[randNum]

answer = input("Enter The State name of " + abbr + ": ")

if answer.lower() == states[abbr].lower():

print("Correct")

correct += 1

else:

print("Incorrect")

incorrect += 1

again = input("Play again? y/n ")

if again.lower() == 'n':

break

print("Correct: " + str(correct))

print("Incorrect: " + str(incorrect))
