Color Mixer
The colors red, blue, and yellow are known as the primary colors because they cannot be made by mixing other colors. When you mix two primary colors, you get a secondary color, as shown here:
- When you mix red and blue, you get purple.
- When you mix red and yellow, you get orange.
- When you mix blue and yellow, you get green.

- circles) Write a program that prompts the user to enter the center coordinates and radii of two circles and determines whether the second circle is inside the first or overlaps with the first, as shown in Figure 4.11. (Hint: circle2 is inside circle1 if the distance between the two centers <= | r1 - r2| and circle2 overlaps circle1 if the distance between the two centers <= r1 + r2.arrow_forwardWidgets and Gizmos An online retailer sells two products: widgets and gizmos. Each widget weighs 75 grams. Each gizmo weighs 112 grams. Write a program that reads the number of widgets and the number of gizmos in an order from the user. Then your program should compute and display the total weight of the order.arrow_forwardDice game Rules of the game: The players roll three dice, and the program adds the sides that turn up. After the first roll of the three dice, a player may choose to roll the dice as many times as they wish until the player gets at least one side 2 from a dice. When a player gets at least one side 2 from the dice, that player's score drops to zero, and the turn switches to the other player. Both players play the game for an equal number of turns, and the player who gets a score higher than 18 wins. If both players get a score higher than 18 within an equal number of turns, the player with the higher score wins. If both of the players got the same scores, print the scores of the players. These are the minimum required functions for this program. Design and implement these functions. You can create more functions if you choose to. Here is the provided starter code: # A program to play a Dice game. import random def roll_die(): ''' Simulate a die roll ''' def…arrow_forward
- C# (Temperature Conversions) Write a temperature conversion program that converts from Fahrenheit to Celsius. The Fahrenheit temperature should be entered from the keyboard (via a TextBox). A Label should be used to display the converted temperature. Use the following formula for the conversion: Celsius=(5/9)×(Fahrenheit−32)arrow_forward(Fraction calculator) | Write a program that lets the user perform arithmetic operations on fractions. Fractions are of the form a/b, in which _a_ and _b_ are integers and b ≠ 0. Your program must be menu driven, allowing the user to select the operation (+, –, *, or /) and input the numerator and denominator of each fraction. Furthermore, your program must consist of at least the following functions: Function menu: This function informs the user about the program’s purpose, explains how to enter data, and allows the user to select the operation. Function addFractions: This function takes as input four integers representing the numerators and denominators of two fractions, adds the fractions, and returns the numerator and denominator of the result. (Notice that this function has a total of six parameters.) Function subtractFractions: This function takes as input four integers representing the numerators and denominators of two fractions, subtracts the fractions, and returns the…arrow_forwardPopulation Tracker Learning Objective: Using Python Repetition and Loop Statements Problem Description Write a Python program (Console and GUI) that predicts the approximate size of a population of organisms. The application should use text boxes to allow the user to enter the following information: starting number of organisms, the average daily population increase (as a percentage), and the number of days the organisms will be left to multiply. For example, assume the user enters the following values: Starting number of organisms: 2 Average daily increase: 30% Number of days to multiply: 10 The program should display the following table of dataarrow_forward
- Java VENDING MACHINE Write a program that simulates a vending machine. The program should display a menu of items, along with the price and quantity of each item. The user can select an item and insert money to purchase the item. The program should display the item purchased, the cost of the item, and the amount of change returned to the user. REQUIREMENTS DECISION STRUCTURES Include at least (1) EACH of the following: ·If-Else-Else If Statements ·Switch Statement LOOPS Include at least (2) DIFFERENT TYPES of loops from the following: ·FOR loop ·WHILE loop ·DO-WHILE loop FILE MANAGEMENT Your project should perform at least (1) of the following tasks: ·READ FROM an input file ·WRITE TO an output file ·READ FROM and WRITE TO the same file METHODS Include at least (10) Methods throughout your Project. Include at least (1) Overloaded Programmer-Defined Method in your Project. JAVA CLASSES Include at least (3) Classes in your Project Include at least (1) Class that inherits…arrow_forward(Game: scissor, rock, paper) Write a program that plays the popular scissor–rock–paper game. Rules: A scissor can cut a paper, a rock can knock a scissor, a paper can wrap a rock. The program should randomly generates a number 0, 1, or 2 representing scissor, rock, and paper. The program should prompt the user to enter a number 0, 1, or 2 and displays a message indicating whether the user or the computer WINs, LOSEs, or DRAWs.arrow_forward20. Random Number Guessing GameWrite a program that generates a random number in the range of 1 through 100, and asks the user to guess what the number is. If the user’s guess is higher than the random number, the program should display “Too high, try again.” If the user’s guess is lower than the random number, the program should display “Too low, try again.” If the user guesses the number, the application should congratulate the user and generate a new random number so the game can start over.Optional Enhancement: Enhance the game so it keeps count of the number of guesses that the user makes. When the user correctly guesses the random number, the program should display the number of guesses. USE RAPTOR PROGRAMarrow_forward
- Coin Converter Lab Description Write a program that asks the user to enter an amount of money in the format of dollars and remaining cents. The program should calculate and print the minimum number of coins (quarters, dimes, nickels and pennies) that are equivalent to the given amount.Hint: In order to find the minimum number of coins, first find the maximum number of quarters that fit in the given amount of money, then find the maximum number of dimes that fit in the remaining amount, and so on. File Name coins.py Score There are five tests each worth 2 points For example, an execution should look like this:Please enter the amount of money to convert:# of dollars: 2# of cents: 37The coins are 9 quarters, 1 dimes, 0 nickels and 2 pennies python labsarrow_forwardProgramming Language: PHP 1. Create a program using if, ifelse, else statement that will ask the user to input two integers. If the first Integer is less than the second integer, get the product of the two input If both integers are equal get the sum of two inputs. Otherwise, divide the integer and get the remainder as output. 2. Create a program using switch statements that will ask the user to input an integer. If the first Integer is less than 10, get the product of the two input If the first integer is equal to 10, get the sum of two inputs. Otherwise, divide the integer to 10 and get the remainder as output.arrow_forward___&Mp99. create a JAVA PROGRAM as a Currency Converter program. The program performs Currency Exchange operation between Saudi Riyals R, Dollars $, Euro € and British Pounds £. The program firstly shows a menu to the user which allows the user to choose one of the possible currency exchange operations and the last option in the menu should allow the user to end the program (see figure1). The menu should be like as figure 1. If the user enters a wrong choice, an error message should appear and the program asks the user to re-enter a correct number. When the user selects an operation, the program do the following: Prompt user to enter the amount to be changed Input amount Calculate and print the result. Once the user presses any key, the menu appears again and the user can choose a new operation. .arrow_forward
