(Use Python) Use the Design Recipe to write a function called which_day that consumes an int representing the number of days that have passed since Friday and returns name of the current day of the week. For example, if 2 days have passed, then ‘Sunday’ should be returned. Include a docstring!
For example:
Test
Result
2
Sunday
4
Tuesday
6
Thursday
8
Saturday
10
Monday
Write 3 assert_equal statements to test your function.
Call main and run all of the functions.
Not: Write some print functions to see the outputs inside each function. (Python programming language)
(Rounding Numbers) Function floor may be
used to round a number to a specific decimal
place. The statement y = floor(x * 10 + .5) / 10;
rounds x to the tenths position (the first
position to the right of the decimal point). The
statement y = floor(x * 100 + .5) / 100; rounds x
to the hundredths position (the second position
to the right of the decimal point). Write a
program that defines four functions to round a
number x in various ways a)
roundTolnteger(number) b)
roundToTenths(number) c)
roundToHundreths(number) d)
roundToThousandths(number) For each value
%3D
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 hun-
dredth, and the number rounded to the nearest
thousandth. IN C PROGRAMMING LANGUAGE

- (Perfect Numbers) An integer number is said to be a perfect number if its factors, including1 (but not the number itself), sum to the number. For example, 6 is a perfect number because 6 =1 + 2 + 3. Write a function isPerfect that determines whether parameter number is a perfect number. Use this function in a program that determines and prints all the perfect numbers between 1and 1000. Print the factors of each perfect number to confirm that the number is indeed perfect.Challenge the power of your computer by testing numbers much larger than 1000.arrow_forward(Quality Points for Student’s Grades) Write a function toQualityPoints that inputs a student’s average and returns 4 it’s 90–100, 3 if it’s 80–89, 2 if it’s 70–79, 1 if it’s 60–69, and 0 if theaverage is lower than 60arrow_forward(Perfect Numbers) An integer is said to be a perfect number if the sum of its divisors, including 1 (but not the number itself), is equal to the number. For example, 6 is a perfect number, because 6=1+2+3. Write a functionisPerfect that determines whether parameter number is a perfect number. Use this function in a program that determines and prints all the perfect numbers between 1 and 1000. Print the divisors of each perfect number to confirm that the number is indeed perfect. Challenge the power of your computer by testing numbers much larger than 1000.arrow_forward
- (FreshFood food[], Write a function named void findFreshFoodDetails int noFood) that prompt the user to input the fresh food details that he/she wants to view the price. Display the fresh food, production place and the total price of the selected fresh food according to kilogram as shown in Figure 4.3. Please enter the type of fresh food you wish to purchase: RED ONION Please enter the production place of RED ONION: INDIA Please enter the weight in kg that you want to view the price of the fresh food :3.5 Fresh Food: RED ONION Production Place: INDIA Total price of 3.5kg is RM 14.00 Figure 4.3. foodDetails.txtarrow_forward(Format an integer) Write a function with the following header to format the inte- ger with the specified width. def format(number, width): The function returns a string for the number with prefix 0s. The size of the string is the width. For example, format(34, 4) returns "0034" and format(34, 5) returns "00034". If the number is longer than the width, the function returns the string representation for the number. For example, format(34, 1) returns "34". Write a test program that prompts the user to enter a number and its width and dis- plays a string returned from invoking format(number, width). Here is a sample run:arrow_forward4. (Prime Numbers) An integer is said to be prime if it is divisible by only 1 and itself. For example, 2, 3, 5 and 7 are prime, but 4, 6, 8 and 9 are not. Write a function called isPrime that receives an integer and determines whether the integer is prime or not. Write a test program that uses isPrime to determine and prints all the prime numbers between 1 and 1000. Display 10 numbers per line.arrow_forward
- (Square of Asterisks) Write a function that displays a solid square of asterisks whose side isspecified in integer parameter side. For example, if side is 4, the function displays: **** **** **** ****arrow_forward(Algebra: solve quadratic equations) The two roots of a quadratic equation ax? + bx + x = 0 can be obtained using the following formula: -b + VB - 4ac -b - Vb - 4ac and r2 2a 2a Write a function with the following header void solveQuadraticEquation(double a, double b, double c, double& discriminant, double& rl, double& r2) b² - 4ac is called the discriminant of the quadratic equation. If the discriminant is less than 0, the equation has no roots. In this case, ignore the value in rl and r2. Write a test program that prompts the user to enter values for a, b, and c and dis- plays the result based on the discriminant. If the discriminant is greater than or equal to 0, display the two roots. If the discriminant is equal to 0, display the one root. Otherwise, display "the equation has no roots". See Programming Exercise 3.1 for sample runs.arrow_forward(Replace strings) Write the following function that replaces the occurrence of a substring old_substring with a new substring new_substring in the string s. The function returns true if string s is changed, and otherwise, it returns false. bool replace_strings (string& s, const string& old_string, const string& new_string) Write a test program that prompts the user to enter three strings, i.e., s, old string, and new_string, and display the replaced string.arrow_forward
