## Requirements and Specifications

Source Code

```#include using namespace std; bool check(int v) { return (-20 <= v) && (v <= 50); } void read15Ints(int* arr, int n) { int counter = 0; int val; while(counter < n) { cin >> val; if (check(val)) { arr[counter] = val; counter++; } else { cout << "Input value is out of bounds" << endl; } } } void showAllBySign(int* arr, int n, bool negative) { cout << (negative ? "Negatives:" : "Non-negatives:"); for (int i = 0; i if (arr[i] < 0 && negative || arr[i] >= 0 && !negative) { cout << " " << arr[i]; } } cout << endl; } void showPositiveSum(int* arr, int n) { cout << "Positive sum:"; int sum = 0; for (int i = 0; i if (arr[i] > 0) { sum += arr[i]; } } cout << sum << endl; } void showArray(int* arr, int n) { cout << "Array:"; for (int i = 0; i cout << " " << arr[i]; } cout << endl; } int main() { int arr[15], n = 15; bool isOver = false; read15Ints(arr, n); while (!isOver) { int choice = 0; cout << "Menu:" << endl; cout << "1. Show all negatives" << endl; cout << "2. Show all non-negatives" << endl; cout << "3. Show positive sum" << endl; cout << "4. Show original array" << endl; cout << "5. Exit" << endl; cout << "Your choice: "; cin >> choice; switch(choice) { case 1: showAllBySign(arr, n, true); break; case 2: showAllBySign(arr, n, false); break; case 3: showPositiveSum(arr, n); break; case 4: showArray(arr, n); break; case 5: isOver = true; break; default: cout << "Invalid input" << endl; break; } cout << endl; } cout << "Good Bye" << endl; } ```
