Question 1 Write a program that asks a user to enter the size of a dynamic
array that stores exam marks obtained by students. Create the dynamic
array and a loop that allows the user to enter an exam mark into each array
element. Loop through the array, find the average mark for the exam and
output it. Delete the memory allocated to your dynamic array before exiting
your program.
#include <iostream>
#include <new> // Required for std::bad_alloc
#include <iomanip> // Required for formatting the output

int main() {
// --- Step 1: Ask the user for the size of the dynamic array ---
int arraySize;
std::cout << "Enter the number of students (size of the array): ";
std::cin >> arraySize;

// Validate that the size is a positive number
if (arraySize <= 0) {
std::cerr << "Error: The array size must be a positive number."
<< std::endl;
return 1; // Exit with an error code
}

// --- Step 2: Create the dynamic array and handle memory allocation
errors ---
// We use a try-catch block to handle the case where memory cannot be
allocated.
