Hello,

Well my advice for Sara when using the web would be 3 things.

1: Never tell anyone where you live,Your name, Or any other personal information.

This is important as it will keep you safe and others that are in your family.

2: Get anti virus hardware on your devise.

This will help to stop bad people, and bugs/glitches,this will also protect you from information thieves.

3: Make sure to keep your passwords saved on paper.

I know a lot of people use, google(ect.) to save there passwords to make everything easy, but a good way to never loss them is to wright them down.

Have a great day!

Create a lottery game application. Generate three random numbers (see Appendix D for help in doing so), each between 0 and 9. Al
Pachacha [2.7K]

The question is not complete! Here is the complete question and its answer!

Create a lottery game application. Generate three random numbers (see Appendix D for help in doing so), each between 0 and 9. Allow the user to guess three numbers. Compare each of the user’s guesses to the three random numbers and display a message that includes the user’s guess, the randomly determined three-digit number, and the amount of money the user has won as follows:

no matches: 0

any one matching: 10$  

two matching: 1000$  

three matching: 100000$  

Code with Explanation:

#include <iostream>

using namespace std;

int main()

{

int matches=0;

int guess_1, guess_2, guess_3;

int num_1, num_2, num_3;

// get 3 digits from the user

cout<<"Enter first guess digit 0 to 9"<<endl;

cin>>guess_1;

cout<<"Enter second guess digit 0 to 9"<<endl;

cin>>guess_2;

cout<<"Enter third guess digit 0 to 9"<<endl;

cin>>guess_3;

// every time program runs srand() generates new random numbers and rand()%10 makes sure that number is single digit 0 to 9

srand(time(NULL));

num_1=rand()%10;

cout<<"First lottery digit: "<<num_1<<endl;

num_2=rand()%10;

cout<<"Second lottery digit: "<<num_2<<endl;

num_3=rand()%10;

cout<<"Third lottery digit: "<<num_3<<endl;

// store random generated numbers and guess numbers in arrays to compare them

int num[3]= {num_1,num_2,num_3};

int guess[3]={guess_1,guess_2,guess_3};

// compare the arrays to find out how many are matching

   for(int i=0; i<3; i++)

   {

 for(int j=0; j<3; j++)

 {

  if(num[i]==guess[j])

  {    

   matches = matches + 1;

  }

 }

}

cout << "Total Matches are: " <<matches << endl;

// display reward according to the number of matches

if (matches==0)

cout<<"you won: $0"<<endl;

if (matches==1)

cout<<"you won: $10"<<endl;

if (matches==2)

cout<<"you won: $1000"<<endl;

if (matches==3)

cout<<"you won: $100000"<<endl;

return 0;

}

Output:

Enter first guess digit 0 to 9

7

Enter second guess digit 0 to 9

1

Enter third guess digit 0 to 9

5

First lottery digit: 3

Second lottery digit: 7

Third lottery digit: 2

Total Matches are: 1

You won: $10

Enter first guess digit 0 to 9

7

Enter second guess digit 0 to 9

3

Enter third guess digit 0 to 9

4

First lottery digit: 5

Second lottery digit: 4

Third lottery digit: 7

Total Matches are: 2
