Chapter 7.1, Problem 7.4CP
Explanation of Solution
Array:
An array is defined as a group that consists of similar data types.
- The array size must be specified by an “int” value and not long or short.
- In Java, all arrays are allocated dynamically.
- An array is always indexed, starting from 0.
Example:
//Create an array variable with size 3
int i[] = new int[3];
In the above statement,
- The “int” refers the data type of the array.
- The “i” refers the name of the array.
- The keyword “new” refers the new memory allocation.
- The “int[3]” refers the size of the array.
Difference between array size declarator and subscript:
In the above example, “3” is the array size declarator and the index specified for each element in the array is called as subscript...

- Lotto Program C++Write a program that simulates the Powerball lottery. 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_forwardInput 5 integer values for an Array with size of 5.
