Question
Chapter 10, Problem 17RQE
Program Plan Intro
Pointer:
Pointer will allow the user to indirectly access and manipulate the variable data contents. A pointer variable will hold the address of the data contents. If an asterisk “*” operator is present before the variable then that variable is referred as pointer variable. An asterisk “*” is also referred as indirection operator is used to dereferences the pointer.
Representing array using pointer notation:
- In general array will have a continuous allocation of memory bytes, to represent the values present in the array it can be represented using its subscript value.
- So to represent the values using pointer notation with an indirection operator the name of the array plus the subscript representing the value needs to be specified.
- When we represent only the array name, it will indicate the first element of the array.
- To represent the next element we need to increment the values by one to find the proceeding elements of the array.

1) Write a program that simulates a lottery. The program should have an array of five integers named winningDigits, with a randomly generated number in the range of 0 through 9 for each element in the array.
The program should ask the user to enter five digits and should store them in a second integer array named player. The program must compare the corresponding elements in the two arrays and count how many digits match.
For example, the following shows the winningDigits array and the Player array with sample numbers stored in each. There are two matching digits, elements 2 and 4.
WinningDigits

4
9
1

player
4

Once the user has entered a set of numbers, the program should display the winning digits and the player’s digits and tell how many digits matched.
