COP2221 - Intermediate C++ Programming Module #6 Assignment One 20 points This assignment refers to Learning Outcome #2: Create and utilize arrays to store lists of related data Programming Problem You have been hired to create a C++ program to simulate the lottery. Your program allows users to see how often their lottery number choices match a randomly generated set of numbers used to pick lottery winners. The company, "How Lucky Are You?, Inc." wants a modular, professional and user-friendly program designed and developed so you need to spend some time on your program's layout (especially the input and output screens). Program Details 1. Your program will use an array of five (5) integer values named, lottery. 2. Generate a random number in the range of 0-9 for each element in the array. If you've not dealt with random numbers - read Section 3.9 (specifically Program 3-25) to cover the material dealing with them. Random numbers are lots of fun - a random number generator is a piece of software that uses a mathematical algorithm to determine a number. Each number is just as likely as being "generated" as any other number. Watch this video: https://www.youtube.com/watch?v=naXUIEAlt4U. Notice that this video uses a slightly different approach to obtaining a value from 1-6 than does the text. Both are fine! 3. The user should then be prompted to enter 5 digits in the range 0-9. Store the user's input in an array named, user. Your program will compare corresponding elements and keep a count of how many digits match. NOTE: you are looking for the same number to be in the same position of each array. 4. Validate the user's input-only the digits 0-9 are acceptable lottery picks. 5. The program will display the lottery array and a message telling the user the number of matching digits he/she entered. If all of the digits in the user's array match the lottery array - display a message stating that the user is a grand prize winner. 6. Function main() should be the overall program driver. You must pass the empty lottery array to a function that will fill the array with random numbers and return to function main(). NOTE: this requirement is for instructional purposes - you need to know how to pass and return an array where the values change in this case, the array changes from no values to randomly generated values). Overall, your

CODE IN C++:

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;
void fillLottery(int *arr){
int i;
for(i=0;i<5;i++){
*(arr+i) = rand()%10;
}
}
int main()
{
srand(time(0));
int lottery[5];
fillLottery(lottery);
int user[5];
cout<<"Enter 5 digits(0-9):"<<endl;
int i ,temp ;
for(i=0;i<5;i++){
cout<<"Enter a digit(0-9):";
cin>>temp;
if(temp<0 || temp > 9){
cout<<"Invalid digit... Enter agian..."<<endl;
i--;
}
else{
user[i] = temp ;
}
}
bool flag = true;
int count = 0 ;
for(i=0;i<5;i++){
if(lottery[i]!=user[i]){
flag = false;
}
else
count+=1;
}
cout<<"Lottery digits are: ";
for(i=0;i<5;i++)
cout << lottery[i]<<" ";
cout<<""<<endl;
cout<<"Number of digits matched:"<<count<<endl;
if(flag)
cout << "User is a grand prize winner"<<endl;
else
cout << "User is not a grand prize winner"<<endl;
return 0;
}

OUTPUT:

input Enter 5 digits (0-9): Enter a digit(0-9):0 Enter a digit(0-9):1 Enter a digit(0-9):2 Enter a digit(0-9):3 Enter a digit(0-9):4 Lottery digits are: 0 8 7 2 1 Number of digits matched:1 User is not a grand prize winner ... Program finished with exit code o Press ENTER to exit console.
