You’re going to write a program that models the Littleton City Lotto (not a real Lotto game). The program is going to allow to user to first select their lotto numbers. The program will then randomly generate the winning lotto numbers for the week and then check the winning numbers against the random ticket the user played in the Lotto to see how many numbers the user guessed correctly.

Explanation:

// Include the required

// header files.

#include <iostream>

#include <cstdlib>

#include <iomanip>

#include <ctime>

#include <string>

// Use the

// standard namespace.

using namespace std;

// Define the function NoDuplicates(),

// to check whether a value is already

// present in an array or not.

int NoDuplicates(int arr[], int size, int val)

{

// Run the loop to

// traverse the array.

for(int i=0; i<size; i++)

{

// If the value is already present

// in the array, return 0.

if(arr[i] == val)

{

return 0;

}

}

// Otherwise, return 1.

return 1;

}

// Define the function getLottoPicks().

void getLottoPicks(int UserTicket[])

{

int currNum;

//

// Run the oop to get 7

// numbers from the user.

for(int i=0; i<7; i++)

{

// Prompt the user

// to enter the number.

cout << "Please enter number "<<i+1<<":";

// Read and store

// the number.

cin >> currNum;

// Run the loop till the

// entered number is valid.

// display an error message.

{

// Otherwise, if the number is

// already present in the array,

// display an error message.

else if(NoDuplicates(UserTicket, i, currNum) == 0)

{

}

// break out of the loop.

// Define the function displayResults().
