Lab 10 - Dynamic Arrays

Your main() program will have a do-while loop that does the following:

• Prompt the user for the number of integers, then verify that the given size is positive.
• Attempt to allocate the array with the new command and check if the allocation failed by putting the following code on the line immediate after the new line (replace ptr with the name of the pointer for your dynamic array):

  if(ptr == NULL) {
    cout << "Error allocating the array.\n";
    exit(1);
  }
  

• Prompt the user to enter in each element and read that data into the array.
• Calculate the average of all the entered elements and print the average to the screen.
• Deallocate the array.
