answer:Here is a sample implementation of a console-based C++ program that meets the specifications provided: ```cpp #include <iostream> #include <vector> #include <algorithm> #include <limits> // Function to read an array of integers from user input std::vector<int> readArray() { std::vector<int> array; int x; std::cout << "Enter integers separated by spaces (or ENTER to finish):n"; while (std::cin >> x) { array.push_back(x); } // Clear any error flags if non-numeric input was entered if (std::cin.fail()) { std::cin.clear(); std::cin.ignore(std::numeric_limits<std::streamsize>::max(), 'n'); std::cout << "Error: Non-numeric input detected.n"; } std::cin.ignore(std::numeric_limits<std::streamsize>::max(), 'n'); return array; } // Function to sort an array of integers in ascending order using selection sort void selectionSort(std::vector<int>& array) { for (size_t I = 0; I < array.size() - 1; ++i) { size_t minIndex = i; for (size_t j = I + 1; j < array.size(); ++j) { if (array[j] < array[minIndex]) { minIndex = j; } } std::swap(array[i], array[minIndex]); } } int main() { while (true) { std::vector<int> array = readArray(); // Check if input was empty if (array.empty()) { std::cout << "No input detected.n"; continue; } selectionSort(array); std::cout << "Sorted array:n"; for (auto x : array) { std::cout << x << ' '; } std::cout << std::endl; // Prompt user to repeat the sorting process with a new input array char choice; std::cout << "Would you like to sort a new array? (y/n)n"; std::cin >> choice; if (choice == 'n') { break; } } return 0; } ``` In this program, the `readArray` function prompts the user to enter integers separated by spaces and returns a vector of integers. If the user enters non-numeric input, an error message is displayed and the input stream is cleared. The `selectionSort` function takes a reference to an array of integers and sorts it in ascending order using the selection sort algorithm. The main function reads an input array using `readArray`, sorts it using `selectionSort`, and outputs the sorted array to the console. It then prompts the user to repeat the sorting process with a new input array or exit the program. The program uses comments to explain each section of the code and uses meaningful variable and function names to improve code readability.

answer:Certainly, here is the `selectionSort` function with comments added to explain how the algorithm works step by step: ```cpp // Function to sort an array of integers in ascending order using selection sort void selectionSort(std::vector<int>& array) { // Traverse the array from the beginning to the second to last element for (size_t I = 0; I < array.size() - 1; ++i) { // Assume the current element is the smallest size_t minIndex = i; // Traverse the remaining unsorted elements to find the smallest element for (size_t j = I + 1; j < array.size(); ++j) { // If an element smaller than the current minimum is found, update the minimum index if (array[j] < array[minIndex]) { minIndex = j; } } // Swap the current element with the smallest element found in the remaining unsorted elements std::swap(array[i], array[minIndex]); } } ``` I hope that helps make the `selectionSort` function easier to understand!

answer:Sure! Here is the `main` function with comments added to explain each section: ```cpp int main() { // Loop to allow the user to repeat the sorting process with a new input array while (true) { // Read an array of integers from the user std::vector<int> array = readArray(); // Check if input was empty if (array.empty()) { std::cout << "No input detected.n"; continue; } // Sort the array in ascending order using selection sort selectionSort(array); // Output the sorted array to the console std::cout << "Sorted array:n"; for (auto x : array) { std::cout << x << ' '; } std::cout << std::endl; // Prompt the user to repeat the sorting process with a new input array or exit the program char choice; std::cout << "Would you like to sort a new array? (y/n)n"; std::cin >> choice; if (choice == 'n') { break; } } return 0; } ``` I hope this makes the `main` function clearer and easier to understand!

answer:Yes, we can add some error handling to handle the case when the user enters an invalid character for the "yes/no" prompt to repeat the sorting process. Here's an updated `main` function with the added error handling: ```cpp int main() { // Loop to allow the user to repeat the sorting process with a new input array while (true) { // Read an array of integers from the user std::vector<int> array = readArray(); // Check if input was empty if (array.empty()) { std::cout << "No input detected.n"; continue; } // Sort the array in ascending order using selection sort selectionSort(array); // Output the sorted array to the console std::cout << "Sorted array:n"; for (auto x : array) { std::cout << x << ' '; } std::cout << std::endl; // Prompt the user to repeat the sorting process with a new input array or exit the program char choice; bool validChoice = false; while (!validChoice) { std::cout << "Would you like to sort a new array? (y/n)n"; std::cin >> choice; if (choice == 'y' || choice == 'n') { validChoice = true; } else { std::cout << "Invalid choice. Please enter 'y' or 'n'.n"; std::cin.clear(); std::cin.ignore(std::numeric_limits<std::streamsize>::max(), 'n'); } } if (choice == 'n') { break; } } return 0; } ``` In this updated version of the `main` function, we added a `validChoice` flag and a `while` loop that will keep prompting the user to enter a valid choice (either 'y' or 'n') until a valid choice is entered. If an invalid character is entered, an error message is displayed, and the input stream is cleared. Once a valid choice is entered, the `while` loop exits, and the program either exits or repeats the sorting process with a new input array based on the user's choice.
