In cell F15, insert a function that will automatically display the word Discontinue if the value in cell D15 is less than 1500,

int currentNumber,previousNumber = -1, countDuplicates = 0;

do {

cin >> currentNumber;

if ( previousNumber == -1) {

previousNumber = currentNumber;

}else {

if ( previousNumber == currentNumber )

countDuplicates++;

else

previousNumber = currentNumber;

}

} while(currentNumber > 0 );

cout << countDuplicates;

Answer:

The code for the solution is implemented using Python 3.

1. import random
2. import string
4. def simulate_several_key_strikes(l):
5.    char_set = string.ascii_lowercase
6.    return ''.join(random.choice(char_set) for i in range(l))
8. print (simulate_several_key_strikes(10))

Explanation:

This program is designed to create random characters, and the quantity of characters produced is determined by the user's input. Therefore, it is necessary to import the random library (Line 1). Additionally, we incorporate the string module to access its associated method for generating English letters (Line 2).

Then, we define the function simulate_several_key_strikes that accepts one parameter, l. Inside this function, the ascii_lowercase method is utilized to establish the character set of lowercase letters, which is stored in the variable char_set (Line 5). The random.choice method randomly selects a character from char_set, concatenating it with an empty string (Line 6). A for-loop is utilized to produce a total of l characters, generating the final output.

To test the function, we input 10 as an argument, producing a sample output such as:

Answer:

C) Flight Simulation software offers pilots a more authentic training experience compared to actual flight sessions.

Explanation:

Flight simulation programs are utilized to instruct future pilots in aviation schools. They replicate the circumstances that pilots will likely encounter during real flights and how to manage them.

This software enables pilots to rehearse landings across various types of landscapes and weather conditions without geographical limitations.

Additionally, it is cost-effective by reducing expenses on fuel and maintenance related to actual training flights.

Nevertheless, it does not engage pilots in a more authentic experience than actual training flights.

Answer:

Below is the complete code for this question:

import os #importing package

def parent_directory():#defining method parent_directory

   dir = os.getcwd()#storing current working directory in dir

   relative_parent = os.path.join(dir) #from dir, define relative_parent variable using join method

   return os.path.dirname(relative_parent)#return the directory name using return keyword

print(parent_directory())#use print to invoke parent_directory method

Output:

/

Note:

This program executes in an online compiler, hence it returns "/"

Explanation:

The provided Python code imports the "os" package, after which it defines a method called "parent_directory" that uses the variable dir to store the current working directory through the "getcwd" method.

• Next, the variable "relative_parent" is defined, using the join method to store the directory value and returning its value.
• Lastly, the print function is called to output the method's result.
