The first program should input the name of the drink and the number of milligrams of caffeine in the drink. It should then output the drink name and the number of drinks it takes to kill a person. For example, if the user enters "coffee" and "160", then the program should output "It will take approximately 62.5 drinks of coffee to kill a person from caffeine."
The second program should perform the same calculation as the first program, but read the name of the drink and the number of milligrams of caffeine in the drink from a file named drink. txt and output the answer to the console.

- A parking garage charges a $20.00 minimum fee to park for up to three hours. The garage charges an additional $5.00 per hour for each hour or part thereof in excess of three hours. The maximum charge for any given 24- hour period is $50.00. Assume that no car parks for longer than 24 hours at a time. Write a program that calculates and printsthe parking charges for each of three customers who parked their cars in this garage yesterday. You should enter the hours parked for each customer. Your program should print the results in a neat tabular format and should calculate and print the total of yesterday’s receipts. The program should use the function calculateCharges to determine the charge for each customer. Your outputs should appear in the following format: Car Hours Charge1 1.5 20.002 4.0…arrow_forwardAirline companies apply baggage restrictions for their passengers. An airline company has decided to apply a 10kg limitation for passengers' hand luggage and 20kg for their normal baggage. When passengers arrive, they enter their hand and normal luggage weight from the keyboard. If passengers exceed their normal baggage allowance of 10 dollars per gram, they pay 12 dollars per kg. Accordingly, write the program that calculates the baggage price of the airline they will go to according to the baggage values entered by the arriving passenger and keeps this from closing the program for each passenger. Note: If hand and normal baggage allowances are stretched below the maximum value, the payment amount will be considered not negative. An example printout is given on the right.

To help a local charity, the theater owner has decided to donate a portion of the gross amount generated from the movie to the charity. This example designs and implements a program that prompts the user to input the movie name, adult ticket price, child ticket price, number of adult tickets sold, number of child tickets sold, and percentage of the gross amount to be donated to the charity. The output of the program is as follows: ** The input to the program consists of the movie name, adult ticket price, child ticket price, number of adult tickets sold, number of child tickets sold and percentage of the gross amount to be donated to the charity. Sample Input: Enter the movie name : Darna Enter the price of an adult ticket: 4.50 Enter the price of a child ticket : 3.00 Enter the number of adult tickets sold : 800 Enter the number of child tickets sold : 1850 Enter the percentage of donation : 10 Sample Output: Movie Name : Darna Number…arrow_forward
- f. A laborant in a laboratory does a number of antigen tests in one day. Write a program that simulates the number of antigen tests done in a day in a laboratory, displays the number of positives and negatives, and calculates the % of positives in one day. Your program needs to first generate a random number that will show the number of tests done in a day. One laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one). Then for each of the tests, your program needs to generate a random number to show whether they are positive or negative. In order to write this program, you need to have the following three functions used by the main function: test result (void): This function generates a test result. It should randomly return either one or zero. 1 means positive test result and 0 means negative test result. float positive percentage (int,int) : This function takes the total number of positives and the total number of tests and returns the % of positives.…arrow_forwardBody Mass Index (BMI) is a measure of health on weight. It can be calculated by taking your weight in kilograms and dividing by the square of your height in meters. Write a program which prompts the user to enter the weight in kgs (integer value) and height in feet and inches (both integers) and then calculates the BMI of the person. Your program first need to convert inches to meters (i.e. inches * 0.0254) and then use the following formula to calculate BMI: weight kilogram / (height_meter)^2 Your program displays the BMI value in two decimal places and the corresponding status as shown in the examples below. Note that one inch is 0.0254 meters and 1 foot is 12 inches. For example: Input Result 62 5 10 89 6 0 45 BMI BMI < 18.5 18.5 s BMI < 25.0 25.0 ≤ BMI < 30.0 30.0 ≤ BMI 7 82 5 Interpretation Underweight Normal Overweight Obese 2 Enter weight (kg): Enter height (feet): Enter height (inches): BMI is 19.61, Normal Enter weight (kg): Enter height (feet): Enter height (inches): BMI is…arrow_forwardGiven the sample code above in generating a random number. Create a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is 2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Don't display the computer's choice yet.) 2. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. (You can use a menu if you prefer.) 13. The computer's choice is displayed. 4. A winner is selected according to the following rules: a. If one player chooses rock and the other player chooses scissors, then rock wins. (The rock smashes the scissors.) b. If one player chooses scissors and the other player chooses paper, then scissor wins. (Scissors cuts paper.) c. If one player chooses paper and the other player…arrow_forward
- You arrive in front of a bridge that you must cross to reach a village before dark. Crossing the bridge is not free - the bridgekeeper asks you to roll two dice to determine the cost. You decide to write a program to verify that he is charging the right price. Your program should read two integers, between 1 and 6, representing the values of each die. If the sum is greater than or equal to 10, then you must pay a special fee (36 coins). Otherwise, you pay twice the sum of the values of the two dice. Your program must then display the text "Special tax" or "Regular tax" followed by the amount you have to pay on the next line.arrow_forwardIn Python Write a program that computes the fuel efficiency for a multi-leg journey. The program will first prompt for the starting odometer reading and then get information about a series of legs. For each leg, the user enters the current odometer reading and the amount of gas used (separated by a space). The user signals the end of the trip with a blank line. The program should print the miles per gallon achieved on each leg and the total MPG for the triparrow_forwardWrite a program that computes the molecular weight of a carbohydrate (ingrams per mole) based on the number of hydrogen, carbon, and oxygenatoms in the molecule. The program should prompt the user to enter thenumber of hydrogen atoms, the number of carbon atoms, and the numberof oxygen atoms. The program then prints the total combined molecularweight of all the atoms based on these individual atom weights:Atom Weight(grams I mole)H 1.00794c 12.01070 15.9994For example, the molecular weight of water (H20) is: 2(1.00794) +15.9994 = 18.01528.arrow_forward
- A parking garage charges a $2.00 minimum fee to park for up to three hours andan additional $0.50 per hour for each hour or part thereof over three hours.

Write a program that will calculate and print theparking charges for each of three customers who parked their cars in this garageyesterday. You should enter the hours parked for each customer. Your programshould print the results in the below format, and should calculate and print thetotal of yesterday's receipts. The program should use the functioncalculateCharges to determine the charge for each customer.arrow_forwardWrite a program that helps a company manage salaries of its employees. Your program should ask for the number of hours worked and the hourly rate of an employee than, display the salary. This program should allow the user to enter the information of many employees until enters -1.
