(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
PLEASE
(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.

Test your function with several calls, each with a different number of arguments.arrow_forward(Use Python) Use the Design Recipe to define a function called black_jack which consumes to 2 int values greater than 0. Return whichever value is nearest to 21 without going over. Return 0 if they both go over. Include a docstring! For example: Test Result print(black_jack(19, 21)) 21 print(blackjack(21, 19)) 21 print(black_jack(19, 22)) 19 Write three assert_equal statements to test your function.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(Rounding Numbers) An application of function floor is rounding a value to the nearestinteger. The statementy = floor(x + .5);will round the number x to the nearest integer and assign the result to y. Write a program that readsseveral numbers and uses the preceding statement to round each of these numbers to the nearestinteger. For each number processed, print both the original number and the rounded number.arrow_forward(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
- (Python)Write a function that receives an integer. The function must return a string containing thehexadecimal representation of the integer.arrow_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(C++ language)arrow_forward
- (Use python):The instructor of a lower division statistics class has assigned you a task: make a function that takes in a student’s score on a scale from 0 to 100 and assigns a letter grade based on the following grade boundaries.arrow_forward(Use Python) Use the Design Recipe to write a function bmi_risk which consumes two positive numeric arguments into parameters, bmi and age and returns a string 'Low', 'Medium', or 'High' according to the following table: Under 45 45 or over BMI less than 22 Low Medium BMI 22 or more Medium High For example: Test Result print(bmi_risk(21.5, 44)) Low print(bmi_risk(30, 27)) Medium Include a docstring! Write three assert_equal statements to test your function.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
