1. You are working for the census bureau and you need to write a program to count the number ofpeople in each of the following age groups: 0 - 16 (16 included) infant, 16 - 29 young, 29 - 55 middleaged, 55 - 75 old, 75 - and older, really old (intervals closed to the left, open to the right). Report thenumber of people in each age group.2. You are again working for the census bureau and they need some statistics regarding the distributionof ages. Write a program to read in a number of ages. (You do not know upfront how many entriesyou have, so you need to keep track of it.) Compute the average age and the age that occurs mostfrequently (some of the ages might be the same). Ages should be read in as integers, the averageshould be a real number. Calculate the population standard deviation using the formula:2Standard deviation =Σ/n-(Στ/n)

(Statistical) In many statistical analysis programs, data values considerably outside the range of the majority of values are simply dropped from consideration. Using this information, write a C++ program that accepts up to 10 floating-point values from a user and determines and displays the average and standard deviation of the input values. All values more than four standard deviations away from the computed average are to be displayed and dropped from any further calculation, and a new average and standard deviation should be computed and displayed.
C++ A company hired 10 temporary workers who are paid hourly and you are given a data file that contains the last name of the employees, the number of hours each employee worked in a week, and the hourly pay rate of each employee. You are asked to write a program that computes each employee's weekly pay and the average salary of all the workers. The program then outputs the weekly pay of each employee, the average weekly pay, and the names of all the employees whose pay is greater than or equal to the average pay. If the number of hours worked in a week is more than 40 hours, then the pay rate for the hours over 40 is 1.5 times the regular hourly rate. Use two parallel arrays: a one-dimensional array to store the names of all the employees, and a two-dimensional array of 10 rows and 3 columns to store the number of hours an employee worked in a week, the hourly pay rate, and the weekly pay. Your program must contain at least the following functions—a function to read the data from the…

1. An iron manufacturing company maintains data about all of its employees, including every employee’s name, unique ID, age, native city, contact number, the department to which she or he belongs, and gross salary. The company wants a program that can sort the employees based on their native city in order to easily trace how many employees belong to the same region. Write a program module by using ‘strcmp’ to sort all the available names of cities in an ascending order.

Write VBA CODE FOR THE FOLLOWING PROBLEM Problem: The Worksheet named Grades contains a place for students to record the grades they have received in their classes. Students put the number of each letter grade received in the B column. (For example, the worksheet currently shows that the student has taken 9 classes and made five As, one B, one C, one D, and one F as grades. You need to write a program that reads the grades from the worksheet and uses a function to calculate the student’s GPA. For this problem you can assume that all classes are worth the same number of credit hours. The function should send back the GPA to the calling procedure. The procedure will then put up a message box that gives the student their GPA and a message about their GPA, all in one message box. The message should be “You qualify for an internship” if the student has a GPA of at least 3.0. It should be “You’re in the danger zone” if the GPA is between 2.0 and 3.0. And it should be “You are on…
The setting: A book publisher needs your help... A book publisher has decided that they need to increase the variety of their children's book titles, both to increase reading comprehension of nonstandard title and because kids find these varied titles more exciting. Write a function to automate their book title validation process. Write a program (called validate_booktitle.py) to check the validity of a book title. To be considered valid, a title must 1. contain at least 1 capital letter, 2. contain at least 2 lowercase letters, 3. contain at least 1 number, 4. contain at least 1 special character from [&], (exclamation point, period, colon, semi- colon, ampersand) 5. have a minimum length of 12 characters, and 6. have a maximum length of 25 characters. We've included a small set of sample tests in test validate booktitle.py. You may want to write more to test your code. Do not turn in test_validate_booktitle.py. As with all the programs this week, we will be testing your code using…
Decryption Key A|B|C| D|E|F|G|H|I|J|K|L|M N|O|P|Q|R|S|T|U|V|W|X|Y|Z (letter above equals below, and vice versa) As you can see, A becomes N, B becomes O and so on. Your job is to write a program, with at least four functions, including main, which must do the following: 1. Ask user whether they want to encode or decode a message - if no, then terminate 2. Take the input string from the user, store it in dynamic memory (use new) 3. As appropriate, encode or decode the message using Rot13. 4. Output the encoded/decoded message 5. Delete the input string from dynamic memory (use delete)
USE PYTHON Source: en.wikipedia.org/wiki/Camel_case In some languages, it’s common to use camel caseLinks to an external site. (otherwise known as “mixed case”) for variables’ names when those names comprise multiple words, whereby the first letter of the first word is lowercase but the first letter of each subsequent word is uppercase. For instance, whereas a variable for a user’s name might be called name, a variable for a user’s first name might be called firstName, and a variable for a user’s preferred first name (e.g., nickname) might be called preferredFirstName. Python, by contrast, recommendsLinks to an external site. snake caseLinks to an external site., whereby words are instead separated by underscores (_), with all letters in lowercase. For instance, those same variables would be called name, first_name, and preferred_first_name, respectively, in Python. In a file called camel.py, implement a program that prompts the user for the name of a variable in camel case and outputs…
C++ - When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by subtracting the smallest value from all the values. The input begins with an integer indicating the number of integers that follow. Ex: If the input is: 5 30 50 10 70 65 the output is: 20 40 0 60 55 The 5 indicates that there are five values in the list, namely 30, 50, 10, 70, and 65. 10 is the smallest value in the list, so is subtracted from each value in the list. For coding simplicity, follow every output value by a space, including the last one.
1) This function returns the number of crashes that occurred between the two dates as aninteger. The start_date and end_date are given as string, in format "09/23/2021".You can use the Python’s datetime module if you want. WE call the function asT.total_number_of_crashes(start_date, end_date)
