4.21 LAB: Leap year - functions A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: 1) The year must be divisible by 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. Your program must define and call the following function. The function should return True if the input year is a leap year or False otherwise.def is_leap_year(user_year) Here is code so far. I am stuck on this one.

19.16 LAB: Area of a triangle Using Heron's formula, you can calculate the area of a triangle if you know the lengths of all three sides. Given the length of each side of a triangle as input, calculate the area of the triangle using Heron's formula as follows: s = half of the triangle's perimeter area = the square root of s*(s-a)*(s-b)*(s-c), where a, b, and c are each sides of the triangle. Hint: Use the math function sqrt() for calculating the square root. Output the floating-point value of the area with two digits after the decimal point using the following statement once before all other cout statements:cout << fixed << setprecision(2); Ex: If the input for a, b, and c is: 3.0 4.0 5.0 the output is: Triangle area = 6.00 #include <iostream>#include <iomanip>#include <cmath>using namespace std; int main() { /* Type your code here. */ return 0;

Alphabetic Telephone Number TranslatorMany companies use telephone numbers like 555-GET-FOOD so the number is easier for theircustomers to remember. On a standard telephone, the alphabetic letters are mapped to numbers519in the following fashion:A, B, and C = 2D, E, and F = 3G, H, and I = 4J, K, and L = 5M, N, and O = 6P, Q, R, and S = 7T, U, and V = 8W, X, Y, and Z = 9Write a program that asks the user to enter a 10-character telephone number in the format XXXXXX-XXXX. The application should display the telephone number with any alphabeticcharacters that appeared in the original translated to their numeric equivalent. For example, ifthe user enters 555-GET-FOOD, the application should display 555-438-3663 For the attached assignment, write a python program, you also need to write: Comments for all the values, constants, and functions IPO Variables Pseudcode

After calculating the percentage of each student store the recordof all 5 students in to a text file by using the concept of filing. Finally display the records of all students in a tabular format
20.15 LAB: Interstate highway numbers Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, I-405 services I-5, and I-290 services I-90. Note: 200 is not a valid auxiliary highway because 00 is not a valid primary highway number. Given a highway number, indicate whether it is primary, auxillary, and what direction(s) it travels.

1. The main function creates 5 pixels with random red, green, and blue values. Complete the id_color function to return “red” if the red value is greater than the green and blue, “green” if the green value is greater than the red and blue, and “blue” if the blue value is greater than the red and green. If there is no clear maximum value (for example, if the red and green values are the same) return None. Do not change the main function.
