Write a program that simulates a lottery. The program should havean array of five integers named lottery, and shouldgenerate a random number in the range of 0 through 9 for eachelement in the array. The user should enter five digits whichshould be stored in an integer array named user. Theprogram is to compare the corresponding elements in the two arraysand keep a count of the digits that match. For example, thefollowing shows the lottery array and the user array with samplenumbers stored in each. There are two matching digits (elements 2and 4).
lottery array: 7,4,9,1,3
user array: 4,2,9,7,3
The program should display the random numbers stored in the lotteryarray and the number of matching digits. If all the digits match,display a message proclaiming the user as a grand prize winner.
Answers
Answer:
Here is the C++ program that simulates lottery:
#include<iostream> //to use input output functions
using namespace std; //to access objects cin cout
int main(){ //start of main function
int size= 5; // size of arrays
int range = 10; //range of random numbers from 0 to 9
int user[size]; // user array
int lottery[size]; // lottery array
for(int i=0;i<size;i++) //iterates through the array
lottery[i]=rand()%range; // generates random number in specified range
cout<<"Enter "<<size<<" digits: "; //prompts user to enter 5 digits
for(int i=0;i<size;i++) //loops through the user array
cin>>user[i]; //reads input digits from user
int match=0; //stores number of matching digits
for(int i=0;i<size;i++) //iterates through array to compare user and lottery arrays
if(user[i]==lottery[i]) //if digit at i-th index of user array matches to that of lottery array
match++; //increments count of matching digits by 1
cout<<"Lottery array: "; // display digits of lottery array
for(int i=0;i<size;i++) //iterates through elements of lottery array
cout<<lottery[i]<<" "; //prints elements of lottery array with a space between them
cout<<endl; //prints a new line
cout<<" User array: "; // prints digits of user array
for(int i=0;i<size;i++) //iterates through elements of user array
cout<<user[i]<<" "; //prints elements of user array
cout<<endl; // prints a new line
if(match==size){ //if all the digits match
cout<<"Congratulations. You are a grand prize winner! "; }//displays this message proclaiming the user as a grand prize winner
else{ // if all digits of user array do not match with lottery array digits
cout<<"Number of digits matched: "<<match<<endl; //displays the number of matched digits
cout<<"Sorry! Better luck next time!" ; //displays this message when all digits don't match
}
}
Explanation:
If you want to keep the size and range fixed then you can use #define before the main() function to give a constant value to size and range as:
#define size 5
#define range 10
The program uses rand() function in order to generate random numbers for lottery array in the range of 0 through 9.
Then the program declares a user array with size = 5 and prompts user to enter 5 digits to stores in user array.
Next the program matches each digit of user array to the corresponding digit of lottery array and if the two digits match then the program increments the match variable by 1 to count the matched digits. For example, lets say lottery has the following elements:
lottery: 7,4,9,1,3
Lets say user array has following elements input by user at console
user: 4,2,9,7,3
Now at first iteration the digit 7 at 0-th index of lottery array is matched to the digit 4 at 0-th index of user array. This index is specified using variable i. These means the first element of lottery array is matched with first element of user array. As these digits are not equal so they don't match and the variable i is incremented to point to the position of next digit.
Now at second iteration the digit 4 in lottery array is matched to the digit 2 of user array. As these digits are not equal so they don't match and the variable i is incremented.
at third iteration the digit 9 in lottery array is matched to the digit 9 of user array. As these digits equal so they match and the variable match is incremented to 1 in order to count the number of matches. So value of match = 1
Now at fourth iteration the digit 1 in lottery array is matched to the digit 7 of user array. As these digits are not equal so they don't match and the variable i is incremented. The value of match also remains the same i.e. 1
at fifth iteration the digit 3 in lottery array is matched to the digit 3 of user array. As these digits equal so they match and the variable match is incremented to 1 in order to count the number of matches. So value of match = 2
Next the loop ends because the value of exceeds 5 which is the size of the array.
Next if(match==size) statement has an if condition which checks if all digits match. This is checked by comparing the count of match variable to the size of the array. The value of match is 2 and value of size is 5 so this means that all the digits do not match. Hence this condition evaluates to false. So the statement in if part will not execute and program moves to the statement: cout<<"Number of digits matched: "<<match<<endl; which displays the value of match variable i.e. 2 as:
Number of digits matched: 2
followed by statement cout<<"Sorry! Better luck next time!" ; which displays the message:
Sorry! Better luck next time!

Lossy compression should be applied to text messages and music while lossless compression should be applied to images and videos
A lossy compression of a file implies that the quality of the file is reduced in order to get the file compressed.
This type of compression can be applied to text messages and music because a reduction in the size and quality will only reduce few details about the text messages and music file.
However, a lossless compression is such that even after the file size is reduced, the quality remains unchanged. This type of compression can be applied to video and pictures because even if the size is reduced, the quality of the files are not expected to change.

Discuss the main characteristics of the database approach and how it differs from traditional file systems.
Answers
The database system allows the creation of a single depository of information, which is updated periodically and which can be used simultaneously by many users, since this type of system allows the effective sharing of all data stored in its depository . In addition, this is a secure system and is very difficult to break into. This is because of the efficiency of the software used to maintain it. However, the use of these softwares can be a little complicated for users, in addition to requiring a high economic cost to obtain them.
The traditional file system, in turn, each user must obtain their own file related to the application they want to run. This may seem dull in comparison to the database, but it is advantageous as it does not require any spending on software, as it is simple and there are several cheap and efficient tools and editors on the market. However, this system is not so safe, it can cause isolation of data and even data inconsistency, which disrupts the entire system.
