- 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_forward(Science: calculating energy) Write a program that calculates the energy needed to heat water from an initial temperature to a final temperature. Your program should prompt the user to enter the amount of water in kilograms and the initial and final temperatures of the water. The formula to compute the energy is Q = M * (finalTemperature – initialTemperature) * 4184 where M is the weight of water in kilograms, temperatures are in degrees Celsius, and energy Q is measured in joules.arrow_forwardA retail store grants its customers a maximum amount of credit. Each customer’s available credit is his or her maximum amount of credit minus the amount of credit used. Write a program that asks for a customer’s maximum amount of credit and then asks for the amount of credit used. The program should then properly display the customer’s available credit. Be sure that you check that the user is entering positive values and that the display is formatted correctly.arrow_forward
- Create a change-counting game that gets the user to enter the number of coins required to make exactly one dollar. The program should let the user enter the num- ber of pennies, nickels, dimes, and quarters. If the total value of the coins entered is equal to one dollar, the program should congratulate the user for winning the game. Otherwise, the program should display a message indicating whether the amount entered was more than or less than one dollar.arrow_forwardGuess The Number Game: write a program that will ask the user to guess a secret numberrandomly generated by your program between 1-10. Player have 3 trials to guess the number.After each trial, you have to inform the user, either he/she has guessed it correctly or not, andthe remaining trials to guess the number. In each trial your program should generate a newrandom number. If user guess at least twice correctly, then shows the message, “you won by 2-1” and vice versa for losing.When game is over, ask the user to play again: If the user types "yes", the game start again.else stop the game.arrow_forwardCoin 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_forward
- // MovieGuide.cpp - This program allows each theater patron to enter a value from 0 to 4 // indicating the number of stars that the patron awards to the Guide's featured movie of the // week. The program executes continuously until the theater manager enters a negative number to // quit. At the end of the program, the average star rating for the movie is displayed. #include <iostream> #include <string> using namespace std; int main() { // Declare and initialize variables. double numStars; // star rating. double averageStars; // average star rating. double totalStars = 0; // total of star ratings. int numPatrons = 0; // keep track of number of patrons // This is the work done in the housekeeping() function // Get input. cout << "Enter rating for featured movie: "; cin >> numStars; // This is the work done in the detailLoop() function // Write while loop here //…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_forwardProblem: Feed Nibble Monster Till Full Write a program that generates a number in [0, 500] at the beginning -- this corresponds to how hungry the monster is -- and keeps asking the user to feed the monster until that number falls to zero. Each time the user feeds the monster a nibble, hunger decreases by the decimal value of the character (i.e. if the user feeds 'A' hunger decreases by 65). But when the user feeds the monster some character that isn't a nibble, the hunger increases by the decimal value of the character (since puking depletes energy). Use while loop. Sample runs: Notice the loop exits after one iteration, because hunger was very low and one nibble made the monster full: Notice hunger increasing after non-nibble (pink highlight): Notice that the program just keeps going when the user feeds the monster only non-nibbles. Do you think the program will keep running forever if the user never gives the monster nibbles?arrow_forward

After every guess, the program tells the user whether their number was too large or too small. In the end, the number of tries needed should be printed. It counts only as one try if they input the same number multiple times consecutively. Based on this, create: a) IPO chart(s) b) Flowchart(s)c) Pseudocode for the following problem set.arrow_forwardSports exercise advisor algorithm. In this algorithm you will start out with a temperature value in Celsius, so you do not need to ask the user for it. First, convert the temperature to Fahrenheit. Then display a recommended sports exercise based on the Fahrenheit temperature as follows: for temperatures between 65 and 80° display tennis, for colder temperatures display ping pong, and for warmer temperatures display canoeing. thanks in advancearrow_forward
