15.5 (Create an investment-value calculator)
Write a program that calculates the future value of an investment at a given interest rate for a specified number of years. The formula for the calculation is: futureValue = investmentAmount * (1 + monthlyInterestRate)years*12
Use text fields for the investment amount, number of years, and annual interest rate. Display the future amount in a text field when the user clicks the Calculate button, as shown in Figure 15.27b
Here is the code for the questions below
pic = makeEmptyPicture(100,100)
pixy = getPixel(pic, 70, 30)
setColor(pixy, blue)
pixie = pixy
setColor(pixie, red)
1.What is the meaning of the instruction pixie = pixy in the code above? which one of this is the answer
a. Make the pixie variable refer to the same pixel object that pixy already refers to
b. Make a copy of the pixel object referred to by pixie, and store it in the variable pixy
c. Make the pixy variable refer to the same pixel object that pixie already refers to
d. Make a copy of the pixel object referred to by pixy, and store it in the variable pixie
2. What color is pixel pixy when this code finishes running?
a. cannot be determined from the information provided
b. magenta
c. blue
d. red
3. What color is pixel pixie when this code finishes running?
a. blue
b. red
c. magenta
d. cannot be determined from the information provided
(1) Prompt the user to enter two words and a number, storing each into separate variables. Then, output those three values on a single line separated by a space. Ex: If the input is: yellow, Daisy, 6
Output: You entered: yellow Daisy 6
(2) Output two passwords using a combination of the user input. Format the passwords as shown below. Ex: If the input is: yellow, Daisy, 6
Output: You entered: yellow Daisy 6
First password: yellow_Daisy
Second password: 6yellow6
(3) Output the length of each password (the number of characters in the strings). Ex: If the input is: yellow, Daisy, 6
Output: You entered: yellow Daisy 6
First password: yellow_Daisy
Second password: 6yellow6
Number of characters in yellow_Daisy: 12
Number of characters in 6yellow6: 8

I want it to generate three random numbers between 0 and 9 (including 0 and 9). Then, the user will input their three guesses of what the winning numbers will be. Next, 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 digits, and the amount of money the user has won. I need to make certain that this application accommodates repeating digits. For example, if a user guesses 1, 2, and 3, and the randomly generated digits are 1, 1, and 1, do not give the user credit for three correct guesses-just one. (From this, it stands to reason that if the randomly generated digits include 2 repeated digits, that they also should be counted as-just one.)
