Chapter 8.6, Problem 8.12CP
Program Plan Intro
Partial initialization of an array:
The C++ program allows the user to initialize the elements of an array while creating the array; the initialization list stores the value in an array in the specific order as they are initialized.
- Additionally, while initializing the array it is no need to initialize all the elements of an array; the uninitialized elements of the array will be set to “0” by default.
- For the “string” array, it stores the empty strings for uninitialized elements.
- If a local array is completely uninitialized, then the elements are stored with the garbage values.
For example:
Consider the following snippet,
// Constant for the array size
const int num_of_days = 6;
// Initialization list
int days[num_of_days] = {1, 2, 3};
In the above example, the sequence of values stored inside the braces and separated with commas is referred as the initialization list.
- The values are stored in the array in below format:
days[0] = 1;
days[1] = 2;
days[2] = 3;
days[3] = 0;
days[4] = 0;
days[5] = 0;
Thus, if an array is partially initialized, then the uninitialized elements will be assigned as “0”.

In Powerball, a ticket is comprised of 5 numbers between 1 and 69 that must be unique, and a Powerball number between 1 and 26. The Powerball does not have to be unique. Hint: You can use an array to represent the 5 unique numbers between 1 and 69, and an integer variable to represent the powerball. The program asks the player if they'd like to select numbers or do a 'quickpick', where the numbers are randomly generated for them. If they opt to select numbers, prompt them to type the numbers in and validate that they are unique (except the powerball), and in the correct range. The program then generates a 'drawing' of 5 unique numbers and a Powerball, and checks it against the user's lotto ticket. It assigns winnings accordingly. Because it is so rare to win the lottery, I suggest hard coding or printing values to when testing the part of the program that assigns winnings.arrow_forward

In the game of battleship, a `~' character entry in the array represents ocean (i.e., not a ship), a `#' character represents a place in the ocean where part of a ship is present, and a `H' character represents a place in the ocean where part of a ship is present and has been hit by a torpedo. Thus, a ship with all `H' characters means the ship has been sunk. Declare a two-dimensional array that is 25 x 25 that represents the entire ocean and an If statement that prints "HIT" if a torpedo hits a ship given the coordinates X and Y. Create a text file of 25 line. Each line has 25 characters. ~ represents water and # represents part of…arrow_forward
