Body 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:

Write 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.
Write a program that computes and displays the charges for a patient’s hospital stay. First, the program should ask if the patient was admitted as an in-patient or an out-patient. If the patient was an in-patient the following data should be entered:
• The number of days spent in the hospital• The daily rate• Charges for hospital services (lab tests, etc.)• Hospital medication charges.If the patient was an out-patient the following data should be entered:• Charges for hospital services (lab tests, etc.)• Hospital medication charges.Use a single, separate function to validate that no input is less than zero. If it is, it should be re-entered before being returned.Once the required data has been input and validated, the program should use two overloaded functions to calculate the total charges. One of the functions should accept arguments for the in-patient data, while the other function accepts arguments for out- patient data. Both functions should return the total charges.

- Please write a program which estimates a user's typical food expenditure. The program asks the user how many times a week they eat at the student cafeteria. Then it asks for the price of a typical student lunch, and for money spent on groceries during the week. Based on this information the program calculates the user's typical food expenditure both weekly and daily. The program should function as follows: How many times a week do you eat at the student cafeteria? 4 The price of a typical student lunch? 2.5 How much money do you spend on groceries in a week? 28.5 Average food expenditure: Daily: 5.5 euros Weekly: 38.5 euros Sample outputarrow_forwarddo it fastarrow_forwardWrite a program that reads in an investment amount, the annual interest rate, and the number of years, and displays the future investment value using the following formula: futureInvestmentValue = investmentAmount x (1 + monthlyInterestRate)numberOfMonths For example, if you enter the amount 1000, an annual interest rate of 4.25%,and the number of years as 1, the future investment value is 1043.33.arrow_forward
- Write a program that calculates how much a person earns in a month if the salary is one penny the first day, two pennies the second day, four pennies the third day, and so on with the daily pay doubling each day the employee works. The program should ask the user for the number of days the employee worked during the month, validate that it is between 1 and 31, and then display a table showing how much the salary was for each day worked, as well as the total pay earned for the month. The output should be displayed in dollars with two decimal points, not in pennies.arrow_forwardYou 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_forward. The progressive income tax rate is mandated as follows: Taxable Income Rate (%) First $20,000 0 Next $20,000 10 Next $20,000 20 The remaining 30 For example, suppose that the taxable income is $85000, the income tax payable is $20000*0% + $20000*10% + $20000*20% + $25000*30%. Write a program called IncomeTaxCalculator that reads the taxable income (in int). The program shall calculate the income tax payable (in double); and print the result rounded to 2 decimal places. For examples, Enter the taxable income: $41234 The income tax payable is: $2246.80 Enter the taxable income: $67891 The income tax payable is: $8367.30 Enter the taxable income: $85432 The income tax payable is: $13629.60 Enter the taxable income: $12345 The income tax payable is: $0.00arrow_forward
