Question

Write a C++ program that simulates a lottery game.

Your program should use functions and arrays.

Define two global constants:

- ARRAY_SIZE that stores the number of drawn numbers (for example 5)

-MAX_RANGE that stores the highest value of the numbers ( for example 9 )

The program will use an array of five integers named lottery, and should generate a random number in the range of 0 through 9 for each element of the array.

The user should enter five digits, which should be stored in an integer array named user.

The program is to compare the corresponding elements in the two arrays and keep a count of the digits that match.

For example:

Lottery array: 7    4    9    1    3

User array     : 4    2    9    7    3

There are two matching digits (elements 2 and 4).

The program should display the random numbers stored in lottery array and the numbers chosen by the user and then give the number of matching digits. If all digits match, display a message proclaiming the user a grand prize winner.

Answer 1

#include<iostream>
#define ARRAY_SIZE 5
#define MAX_RANGE 10
using namespace std;
int main(){
int arr[ARRAY_SIZE];
int lottery[ARRAY_SIZE];
for(int i=0;i<ARRAY_SIZE;i++)
lottery[i]=rand()%MAX_RANGE;
cout<<"Enter "<<ARRAY_SIZE<<" elements: ";
for(int i=0;i<ARRAY_SIZE;i++)
cin>>arr[i];
int count=0;
for(int i=0;i<ARRAY_SIZE;i++)
if(arr[i]==lottery[i])
count++;
cout<<"Lottery :";
for(int i=0;i<ARRAY_SIZE;i++)
cout<<lottery[i]<<" ";
cout<<endl;

cout<<"User :";
for(int i=0;i<ARRAY_SIZE;i++)
cout<<arr[i]<<" ";
cout<<endl;

if(count==ARRAY_SIZE){
cout<<"Congratulations... grand prize winner";
}
else{
cout<<"There are "<<count<<" matching digits" ;   
}
}

Enter 5 elements: 1 Lottery :3 6 75 3 User 1 2 3 45 There are 0 matching digits ..Program finished with exit code 0 ress ENTER to exit console
