Write a program that simulates a lottery. The program should havean array of five integers named lottery, and shouldgenerate a r
Fiesta28 [93]

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!

Which of the following are agricultural industry clusters? Human population systems, computer technoloy biotechnology or food pr
GalinKa [24]

Biotechnology

Food Products and Processing Systems.

Further explanation

Career clusters help prepare learners with knowledge that they need to use towards achieving their career goals. One such career cluster is the Agriculture, Food, and Natural Resources career cluster which is divided into seven pathways. They include:

  • Food Products and Processing Systems.
  • Biotechnology Systems
  • Agribusiness Systems
  • Plant Systems
  • Animal Science
  • Environmental Service Systems
  • Natural Resource Systems

This brings us to our answers above. Those working in the Food Products and Processing Systems pathway are responsible in discovering new food sources and coming up with ways to process and store food set out by industry regulation. On the other hand, biotechnology systems deal with techniques that use science to solve problems concerning living organisms and anyone thinking about pursuing this pathway ought to demonstrate competence in the application of biotech in the context of Agriculture, Food, and Natural Resources.

#include
Artist 52 [7]

Answer:

#include <iostream>

#include <vector>

using namespace std;

int main() {

const int NUM_VALS = 4;

vector<int> testGrades(NUM_VALS);

int i = 0;

int sumExtra = -9999; // Assign sumExtra with 0 before your for loop

testGrades.at(0) = 101;

testGrades.at(1) = 83;

testGrades.at(2) = 107;

testGrades.at(3) = 90;

/* Your solution goes here */

sumExtra = 0;

for(i = 0; i <= testGrades.size() -1; i++){

   if(testGrades.at(i) > 100){

       sumExtra = sumExtra + (testGrades.at(i) - 100);

   }

}

cout << "sumExtra: " << sumExtra << endl;

return 0;

}

Explanation:

Looks like you almost solved the question. I highlighted the parts you have been missing above.

In order to use vectors in C++, you need to add the vector library at the beginning of the program, #include <vector>

In order to initialize the vector, you need to specify its type inside <int>, since we work with the integers in the question the type must be <em>int</em>
