Here is the main function in a program int main () { int x = 30; //more code goes here someFunction (x) ; cout « x; return 0; } Assume the heading for someFunction is written correctly with an integer parameter named x, and that this is the body of that function: { x = x * 20; //more code goes here } What will be the output? Just enter a number. If there would be an error, enter -999
Raha is a wholesale company for selling furniture. This company would like to change the system to add tax for accepted orders. Write a python program using void function with parameters concept. • Function accepts the number of items as a parameter. • Use loop to do the following, Accept the quantity of the item from the user. Accept the price of each quantity from the user. Calculate the order price, Order price = Price of each quantity * Number of quantities • Calculate the order price after tax, Order price after adding tax = Order price + (Order price * 0.03) • Display the sum of order price after adding taxes for all the orders. Call the function with two types of items. Sample output: Enter the quantity of item 1: 100 Enter the unit price of item 1: 10 Enter the quantity of item 2: 200 Enter the unit price of item 2: 5 Total price for all orders after adding taxes is: 2060.0 Your are required to copy and paste the code in the given white area below the question.

Create a Python function “PolarToCartesian” that allows the user to convert from polar form to Cartesian form and vice versa. The function should print the result of conversion.Write a main code in which the user should choose the conversion he/she wants, then he/she should enter the number (real part and imaginary part if the input number is Cartesian, magnitude and phase if the input number is Polar)You can import ‘numpy’ for trigonometric functions and square root calculations, and you can import ‘math’ for math.pi number.
One lap around a standard high-school running track is exactly 0.25 miles. Define a function named laps_to_miles that takes a number of laps as a parameter, and returns the number of miles. Then, write a main program that takes a number of laps as an input, calls function laps_to_miles() to calculate the number of miles, and outputs the number of miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print (f'{your_value:.2f}') Ex: If the input is: 7.6 the output is: 1.90 Ex: If the input is: 2.2 the output is: 0.55 The program must define and call the following function: def laps_to_miles (user_laps) 461710.3116374.qx3zqy7 LAB ACTIVITY 7.8.1: LAB: Track laps to miles 1 # Define your function here 2 3 if __name__ 4 main.py == '__main__': #Type your code here.

Write in Python Write a function named max that accepts two float values as arguments and returns the value that is the greater of the two. For example, if 7.2 and 12.1 are passed as arguments to the function, the function should return 12.1. Use the function in a program that prompts the user to enter two float values. The program should display the value that is the greater of the two.
Write a wholly creative quiz program that consists of three original questions that you make up according to these specifications: One question should require user input of type int • One question should require user input of type float • One should require a string input The quiz should be scored by using a counter variable that has an initial value of zero and is incremented by one for every correct answer. Provide feedback to the user for each question, and report the total score when the quiz has finished. Example runs not shown. It's a creative exercise. def main(): points = 0 states = int(input('How many states in the USA? ')) if states == 50: points +=1 print('Correct. Good job!') else: print('Sorry, the answer is 50') points = 0 capital = input('What is the capital of England? ") if capital == "London": points+=1 print('Correct. Well done.") else: print('Sorry, the answer is London .) points = 0 points = float(input('How many points does a pentagram have? ")) if points == 10:…

How can I write a python program with a main function that imports a custom module file. The custom module file defines a function that takes the radius of a circle as its only parameter. In the module's custom function: calculate the area and circumference of the circle and use an f-string to print one precisely formatted line as follows: the radius should display centered with one decimal place in a column 8-characters wide. the area should be centered with four decimals in a column 12-characters wide. the circumference should also be centered with four decimals in a column 12-characters wide. outputs in the thousands should display commas. In the main function: print headings for the columns with the same alignments and widths. run a loop that will go through seven iterations. inside the loop generate a random integer from 40-80, inclusive. execute the function in the custom module with the random integer as its argument.
Use Python to write a function display(num). The value of num is the parameter. If num is even, the function will display the even numbers in the range of 1 to num (both inclusive). If num is odd, the function will display the odd numbers in the range of 1 to num (both inclusive).
Create a custom Python module named functions.py. This module must contain two functions: one that converts from Dollars to Pounds and one that converts from Pounds to Dollars. These functions must be named convertdp ( used when P is selected ) and convertpd ( used when D is selected ). These 2 functions are to return a single full precision float value, all print statements are to be in program53. Use 1.26634 for the conversion factor, example 1 Pound currency would be equivalent to 1.27 Dollars Write a program named program53.py , which imports the functions from module functions.py. The program's main() should prompt the user to specify D or P as choices then call the appropriate function which was imported. Conversion accuracy should use full precision ( 5 decimal places as provided above ) for the calculations , and display then print the result to two decimal places. Use the import keyword: import functions from * . The call the functions, would be functionname() Output…
