Body Mass Index
Write a program that reads names, weights, and heights from bmi.dat (provided with starter code; do not change the file name). 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.
Your output should look like
A person’s weight…

Programming Project Assignment
Program Description:
This assignment focuses on while loops and random numbers. Turn in a file named
Lab4_yourFirstName.cpp.
Your program allows the user to play a game in which the program thinks of a random integer and
accepts guesses from the user until the user guesses the number correctly. After each incorrect guess,
you will tell the user whether the correct answer is higher or lower.
The below shows one sample execution of your program. Your output will differ depending on the
random numbers chosen and user input typed, but the overall output structure should match that
shown below:
I am thinking of a number between 1 and 100
Your guess? 50 [Enter]
It's lower
Your guess? 25 [Enter]
It's higher
Your guess? 35 [Enter]
It's lower
Your guess? 30 [Enter]
It's higher
Your guess? 32 (Enter]
It's lower
Your guess? 31 [Enter]
You got it right in 6 guesses!
Do you want to play again? Y[Enter]

1. Random numbers
File: random_numbers.py
(Quick note: NEVER name your files the same as a Python module. If you call this file random.py it won't let you import the real random.)
(Another quick note: Don't let yourself get stuck on something for too long. If one part of one question starts taking you too long, just leave it, move on and come back to it later.)
Write a complete Python program that ask the user for quantity of random numbers and a maximum, then generates and store that many numbers between 0 and the maximum. When you've got this part working, add the following interesting additions:
minimum
maximum
random choice from existing list (Hint: if there are 7 numbers it will be a number at a random index 0-6)
the list reversed*
the list sorted*
Note*: Python's .reverse() and .sort() list methods do NOT return the reversed or sorted list... they modify the list in place.So, if you write something like:
print(numbers.sort())
You will not get what you expect. You'll sort the…

- C programming language Criteria graded: Declare file pointers Open file Read from file Write to file Close file Instructions: Write a segment of code that opens a file called “numbers.txt” for reading. This file is known to have 10 numbers in it. Read in each number and print a ‘*’ to the screen if the number is even. If the number is odd, do nothing. Conclude by closing this file.arrow_forwardCharacter Analysis Create a source code text file and save it as named text.txt. Write a program that reads the file's contents and determines the following: - The number of uppercase letters in the file. - The number of lowercase letters in the file. - The number of digits in the file. - The number of whitespace characters in the file. * Note: Please be sure to use the Python program when creating the program. Thanks!arrow_forwardHere are the two programs which you may choose from to do this program: 1. Using Files - Student Line Up Modify the Student Line Up program described in Programming Challenge 14 which states: "A teacher has asked all of her students to line up according to their first name. For example, in one class Amy will at the front of the line, and Yolanda will be at the end. Write a program that prompts the user to enter the number of students in the class, then loops to read that many names. Once all of the names have been read, it reports which student would be at the front of the line and which one would be at the end of the line. You may assume that no two students have the same name. You are now to do this program reading names from a file. Names should be read in until there is no more data to be read. I am providing for you a file named LineUp.txt for you to use in writing this program. I suggest that you write it first without the file and then modify to add the file.arrow_forward
- Program Description: The project is a student management system which maintains student records in a simple text file. Your task is to write a program to save a list of students records in a FILE and then perform several operations on this FILE. Your program will ask user to choose the option from a menu. The 3 major function in menu are: ADD STUDENT FIND STUDENT PRINT LIST Exit How it Works The menu is handled by do while and switch statement. Sample output The Methods to be implemented are as follows: 1. ADDSTUDENT This method will add a new student to the file. It takes 3 parameters ( student name, id, and GPA). Your program must ask the user to enter the details of new students: Name, ID and GPA 2. FINDSTUDENT This method will search for a student with his/her id in the file. If the student is found it will print her/his record to the output. If the student is not found it will print “There is no record of this student in this system” 3.

The program should display the contents of the file on the screen. Each line of screen output should be preceded with a line number, followed by a colon. The line numbering should start at 1. Here is an example: George Rolland 127 Academy Street Brasstown, NC 28706 If the file's contents won't fit on a single screen, the program should display 24 lines of output at a time, and then pause. Each time the program pauses, it should wait for the user to strike a key before the next 24 lines are displayed.

(You can make up your data, or get it online ) Write a program that declares a struct to store the data for a player. Declare an array of 10 components to store the data for 10 baseball players. The program prints out a menu (in a loop, so this can be done again and again) giving the user a choice to: print out all users and statistics print out the statistics for a specific player print out all data for a specific team update the data for a particular player (change one of the statistics) DO ALL WORK IN FUNCTIONS.

- Finish this program from the code posted below! Note: There should be two files Main.py and Contact.py You will implement the edit_contact function. In the function, do the following: Ask the user to enter the name of the contact they want to edit. If the contact exists, in a loop, give them the following choices Remove one of the phone numbers from that Contact. Add a phone number to that Contact. Change that Contact's email address. Change that Contact's name (if they do this, you will have to remove the key/value pair from the dictionary and re-add it, since the key is the contact’s name. Use the dictionary's pop method for this!) Stop editing the Contact Once the user is finished making changes to the Contact, the function should return.
