answer:Here's a simple C++ program that does what you've described: ```cpp #include <iostream> int main() { int numbers5; double sum = 0; // Read five integers from user input for (int i = 0; i < 5; i++) { std::cout << "Enter integer " << i + 1 << ": "; std::cin >> numbersi; sum += numbersi; // Add the current number to the sum } // Calculate and output the average double average = sum / 5; std::cout << "The average of the five integers is: " << average << std::endl; return 0; } ``` To run this program, copy-paste the code into a file named `main.cpp` and compile it using a C++ compiler like `g++`. You can then run the compiled program to input the five integers and see the output. Please note that this program doesn't check for invalid user input (e.g., non-integer values). If you need help adding error checking, please let me know in the comments.,#include <iostream> using namespace std; int main() { int numbers5; float sum = 0; int index = 0; // Read five integers from the user and store them in the array for (int i = 0; i < 5; i++) { cout << "Enter an integer: "; cin >> numbersi; sum += numbersi; } // Calculate the average of the array float average = sum / 5.0; // Output the average cout << "The average of the array values is: " << average << endl; return 0; } To use the program, simply copy and paste the code into a C++ compiler, and then run the program. You'll be prompted to enter five integers one by one. Once you've entered all five numbers, the program will output the average of the numbers.,#include <iostream> #include <vector> using namespace std; int main() { vector<int> numbers(5); double sum = 0; for (int i = 0; i < 5; i++) { cout << "Enter number " << i + 1 << ": " ; cin >> numbersi; sum += numbersi; } double avg = sum / 5; cout << "Average of the numbers: " << avg << endl; return 0;}

answer:using System; class Program { static bool IsEven(int number) { return number % 2 == 0; } static void Main(string args) { int input = 42; bool result = IsEven(input); Console.WriteLine(result); }},Here's a C# code snippet that tests whether a given integer is even and returns true if it is: ```csharp public static bool IsEven(int number) { return (number % 2 == 0); } // Testing int number = 42; if(IsEven(number)) { Console.WriteLine("The given number is even."); } else { Console.WriteLine("The given number is not even."); } ``` In this example, the `IsEven` function calculates the remainder of `number % 2`, where 'number' is the given integer. If the remainder is 0, then the number is even and the function returns `true`; otherwise, it returns `false`. When testing with the number 42, since 42%2 = 0, the function `IsEven` returns true, and the output is "The given number is even.", Here is a simple C# function that tests whether a given integer is even: ```csharp public bool IsEven(int number) { return number % 2 == 0; } ``` This function takes an integer as an argument and returns a boolean value. It uses the modulus operator to find the remainder of the division of the number by 2. If the remainder is 0, then the number is even, and the function returns true. Otherwise, it returns false.

answer:You can use the following Python program to read the content of a text file, count the frequency of each word and display the results as a dictionary. Remember to replace `'test_file.txt'` with your actual file path. ```python import re def count_words(filename): with open(filename, 'r') as file: text = file.read().lower() words = re.findall(r'bw+b', text) word_freq = {word: words.count(word) for word in set(words)} return word_freq filename = 'test_file.txt' word_freq = count_words(filename) print(word_freq) ``` This code defines a function called `count_words` that takes a filename as an argument. It opens the file, reads its content, converts it to lowercase, extracts the words using regular expressions, calculates the frequency of each word, and returns the result as a dictionary. Finally, it calls this function with the provided filename and prints the resulting dictionary.,Here's a Python program that reads the content of the specified text file and counts the frequency of each word, displaying the results as a dictionary. Please ensure the file path and content are correct. ```python import os from collections import defaultdict # Define the file path and content filename = 'test_file.txt' content = 'hello worldnthis is a testnhello again' # Create a dictionary to store word frequencies word_freq = defaultdict(int) # Split the content into words, ignore capitalization, handle punctuation content = content.lower() words = word for word in content.split() if word.isalnum() # Count the frequency of each word for word in words: word_freqword += 1 # Print the results as a dictionary print(word_freq) ``` Note: The program uses a `defaultdict` from the `collections` module to handle cases where a word does not yet exist in the dictionary. Because defaultdict automatically returns 0 when a key is not in the dictionary, this handles cases where any words appear multiple times in the text file.,def count_words(filename): with open(filename, 'r') as file: content = file.read() words = content.split() word_count = {} for word in words: word_countword = word_count.get(word, 0) + 1 return word_count filename = 'test_file.txt' result = count_words(filename) print(result)

answer:def extract_domain(email): # Split the email into name and domain name, domain = email.split('@') return domain # Example usage email = "[email protected]" domain = extract_domain(email) print(domain), Here is a simple Python function that extracts and prints the domain name from an email address: ```python def extract_domain(email): # Split the email address by '@' symbol domain_and_username = email.split('@') # The second part of the split will be the domain name domain = domain_and_username1 print(domain) # Test the function extract_domain('[email protected]') ``` This function works by splitting the email address at the '@' symbol. The part after the '@' symbol is the domain name, so we print that.,def extract_domain(email): domain = email.split('@')-1 return domain email = '[email protected]' print(extract_domain(email))
