In C++
Create a function called SuperRandomNumber. It should accept a number called top as the argument. It should output to a file 100 random numbers below top.
Code should be in Python, please
Complete the check_character() function which has 2 parameters: A string, and a specified index. The function checks the character at the specified index of the string parameter, and returns a string based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character.
Ex: The function calls below with the given arguments will return the following strings:
check_character('happy birthday', 2) returns "Character 'p' is a letter"check_character('happy birthday', 5) returns "Character ' ' is a white space"check_character('happy birthday 2 you', 15) returns "Character '2' is a digit"check_character('happy birthday!', 14) returns "Character '!' is unknown"
Common Time Zones
Function Name: commonTimeZones()
Parameters: code1( str ), code2( str)
Returns: list of common time zones ( list )
Description: You and your friend live in different countries, but you figure there's a chance that
both of you might be in the same time zone. Thus, you want to find out the list of possible time
zones that you and your friend could both be in. Given two country codes, write a function that
returns a list of the time zones the two countries have in common. Be sure not to include any
duplicate time zones. If the two country codes do not have any common time zones, return the
string 'No Common Time Zones' instead.
Note: You can assume that the codes will always be valid.
example test cases:
>>> commonTimeZones('can', 'usa')
[UTC-08:00', 'UTC-07:00', 'UTC-06:00', 'UTC-05:00', 'UTC-04:00]
>>> commonTimeZones('rus', 'chn')
[UTC+08:00]

Use the information to calculate and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula: BMI = weight × 703 / height2 where weight is measured in pounds and height is measured in inches. The file is in the format name weightInKG heightInCM You will read the name, weight and height for 4 people from the file, and you will need to convert the weights in the file to pounds (note that 1 kilogram = 2.2 pounds) and the heights to inches (2.54 cm = 1 inch). The program should display the person's name along with the calculated BMI and a message indicating whether the person has optimal weight, is underweight, or is overweight.
