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

You won: $1000

Write a program that print "Censored" if userInput contains the word "darn", else print userInput. End with newline.
Ainat [17]

Answer:

userInput = input("Please enter a string of words ")

userInput.split ()

for item in userInput.split ():

   if item =="darn":

       print("Censored")

       break

else:

   print(userInput)

Explanation:

Using Python programming language, the input function is used to receive the users input and save in a variable userInput

Then the .split method is used to convert the words into a list of words.

Using a for loop, the code checks for the word darn and prints censored if it exists else it prints the userInput

The light you shoot in will dictate what shutter speeds to use.
Nesterboy [21]

Answer:

The three things that will determine your exposure are film speed, aperture and shutter speed. The speed of the film dictates how much light the film needs. The aperture controls how much light comes through the lens. And the shutter speed then controls how much of that light hits the film. These three things always work together to produce your image.

The shutter speed, sometimes known as exposure time, determines the amount of time your film is exposed to light when taking a photograph. So, you always need to balance your aperture and shutter speed to get a correct exposure.

The general rule is you need to shoot with at least 1/60 to get sharp images when shooting handheld. It is best to use a tripod if you want to shoot with a slower exposure time as this will help reduce any camera shake.

Fast Shutter

Fast speeds are really good for freezing fast-moving subjects. You need to make sure you are using a fast exposure time if you are trying to take a sharp image of a fast subject. Different cameras have different options but commonly you can choose something like 1/500.

Higher ISO film will also allow you to utilise the faster shutter speeds as they are more sensitive to light.

Slow Shutter

Slow shutter speeds will visibly record motion. They are often used to create the effect of motion in an image. A moving subject captured with a slow exposure time will be captured as a blur across the image. Slow exposure times are also necessary when taking photos at night. They allow you to get enough light to expose your image correctly.

Be careful when using slow exposures without a tripod. The slower the shutter the more likely that you will have visible camera shake in the image.

Reading Shutter Speeds

Shutter speed is measured in fractions of a second. So, for example, 1/60 is read as one-sixtieth of a second. The bigger the second number in the faster the speed.

Typical shutter speeds you will see are; 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250 and 1/500.
