(General math) a. A balance has the following weights: 100 lb, 50 lb, 10 lb, 5 lb, and 1 lb. The number of 100 lb and 50 lb weights required to weigh an object weighing WEIGHT pounds can be calculated by using the following C++ statements:
Using these statements as a starting point, write a C++
b. Without compiling or running your program, manually check the effect of each statement in the program and determine what’s stored in each variable as each statement is encountered.

- ( C PROGRAMMING ONLY) 2. Solving a Person's Lonelinessby CodeChum Admin It's been 1,245 years and our sole Person is getting lonelier each day. This Person definitely needs a partner! Thus, we need to update our Person's design to have a gender as well and there shall be male and female! Instructions: In the code editor, you are provided with the definition of a struct Person. This struct needs an integer value for its age. Furthermore, you are provided with a displayPerson() function which accepts a struct Person as its parameter.Your task is to first update the struct Person so that it can have a gender as well. For this program, we shall represent a gender with a single character: 'M' for male and 'F' for female.Then, create a Person, take in an integer user input and a character user input, and then set them as the Person's age and gender respectively.Finally, call the displayPerson() function and pass that Person you created.Input 1. The age of the Person 2. The gender of…arrow_forward(Use Python) The function course_average should calculate and return the average of the three values pass to it. The function main should ask the user to enter three grades and then pass these values to the course_average function. This function should also display a message to the user in the format below. For example, if the user entered 100, 90 and 95 the message would be:The average of 100 , 90 and 95 is 95arrow_forward(Using Visual Basic language) Marketing Terms? The markup of an item is the difference between its selling price and its purchase price. Two other marketing terms are percentage markup=makeup/(purchase price) and profit margin= makeup/(selling price) where the quotients are expressed as percentages. Write a program that computes the markup, percentage markup, and profit margin of an item. Note: The output format of your program should be exactly the same as given below One possible outcome: Enter purchase price: 215 Enter selling price: 645 Markup: $430.0 Percentage markup: 200.0% Profit margin: 66.67%arrow_forward
- (Java) The greatest common divisor of two positive whole numbers and n1 and n2 is the largest number g such that g evenly divided into both n1 and n2. Write a complete program that takes two positive whole numbers from the user and displays the common divisor.arrow_forward(Geometry: great circle distance) The great circle distance is the distance between two points on the surface of a sphere. Let (x1, y1) and (x2, y2) be the geographi- cal latitude and longitude of two points. The great circle distance between the two points can be computed using the following formula: d = radius * arccos(sin(x1) * sin(x2) + cos(x1) * cos(x2) * cos(y1 - y2)) Write a program that prompts the user to enter the latitude and longitude of two points on the earth in degrees and displays its great circle distance. The average earth radius is 6,378.1 km. The latitude and longitude degrees in the formula are for north and west. Use negative to indicate south and east degrees.arrow_forwardCreate a C++ program that uses a function to calculate and display monthly electricity bill based on the customer's electricity consumption units. [Use Global variables] a) Up to 2000 units of electricity, a charge of 30 Fils per unit is applied (1 AED 100 Fils) b) For consumption of more than 2000 units but less than 4000, a charge is calculated using the following scale: the first 2000 units are charged at 30 fils, and the remaining units are charged at 40 Fils. Note: 5% VAT to be added to the total bill amount. The user must enter the number of units consumed, and the program should calculate the total bill in UAE Dirhams. A screenshot is provided below, which you may find useful (data used here just for illustration purpose) Electricity Bill Calculator. Please input Your Monthly Electricity ConsumptioninUnits:2500 Your Electricitybill: 840AED If any data is missing, make an appropriate assumption. ED F9 F3 F4 F5 F6 F7 F8 23 3 & 4 1 5V 8.

- ( (A + B ) * (C – D) + E / F ) – G Using manual and algorithmic methods, write the following expression to postfix form:arrow_forward(Rounding Numbers) Function floor can be used to round a number to a specific decimal place. The statementy = floor(x * 10 + 0.5) / 10;rounds x to the tenths position (the first position to the right of the decimal point). The statementy = floor(x * 100 + 0.5) / 100;rounds x to the hundredths position (the second position to the right of the decimal point). Write a program that defines fourfunctions to round a number x in various ways:A. roundToInteger(number)B. roundToTenths(number)C. roundToHundredths(number)D. roundToThousandths(number)For each value read, your program should print the original value, the number rounded to the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hundredth and the number rounded to the nearest thousandth.arrow_forward(PYTHON) A nutritionist who works for a fitness club helps members by evaluating their diets. As part of her evaluation, she asks members for the number of fat grams and carbohydrate grams that they consumed in a day. Then, she calculates the number of calories that result from the fat, using the following formula: calories from fat = fat grams x 3.9 Next, she calculates the number of calories that result from the carbohydrates, using the following formula: calories from carbs = carb grams x 4 The nutritionist asks you to write a program on *PYTHON* that will make these calculations.arrow_forward
- (c++) int x = 0, y = 10, z = -5; while ( z < x || y > x ) { y + = z; x -- ; z ++; } x = y = z =arrow_forward(Java) Write a program that reads two numbers from the keyboard representing, respectively, an investment and an interest rate (you will expect the user to enter a number such as .065 for the interest rate, representing a 6.5% interest rate). Your program should calculate and output (in $ notation) the future value of the investment in 5, 10, and 20 years using the following formula: future value = investment * ( 1 + interest rate )year We will assume that the interest rate is an annual rate and is compounded annually.arrow_forward(in Python) Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('{:.2f}'.format(your_value)) Ex: If the input is: 20.0 3.1599 the output is: 1.58 7.90 63.20 Your program must define and call the following driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles. Ex: If the function is called with: 50 20.0 3.1599 the function returns: 7.89975 def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon) Your program should call the function three times to determine the gas cost for 10 miles, 50 miles, and 400 miles.arrow_forward
