This Program should be done using C language Implement the Customer component following the requirements below using C Language... Requirements- Represent the Customers in your code using a 3D character array The maximum number of customers that can be saved is 128. Create a function list_customer which lists all customer data resembling the example run below. Create a function add_customer which prompts the user to input new customer information. Your code should check to make sure the customer does not already exist before adding it to the 3D array. Also check that the customer can be added based on the maximum number of customers in the system. Create a function get_customer which searches the customer data given an customer ID. If the customer exists, return the index within the data that the customer was found. Create a function find_customer which accepts a string containing the name of an customer to search for. It should return the index of the customer in the database. Each…
Write a function which will take 2 arguments. They are: • Sentence • position Your first task is to take these arguments as user input and pass these values to the function parameters. Your second task is to implement the function and remove the characters at the index number which is divisible by the position (Avoid the index number 0 as it will always be divisible by the position, so no need to remove the index 0 character). Finally, add the removed characters at the end of the new string. Return the value and then finally, print the new string at the function call. Input: "I love programming." 3 Function call: function_name("I love programming.", 3) Output: I lveprgrmmngo oai. Input: "Python is easy to learn. I love python." 6 Function call: function_name("Python is easy to learn. I love python.", 6) Output: Pythonis eay to earn.l lov pythn. sl eo
Part B - reading CSV files You will need a Python repl to solve part B. Define a Python function named cheapest_rent_per_state that has one parameter. The parameter is a string representing the name of a CSV file. The CSV file will be portion of a dataset published by the US government showing the median (middle) rent in every county in the US. Each row in the CSV file has the same format Area Name, Efficiency, 1-Bedroom, 2-Bedroom, 3-Bedroom, 4-Bedroom, State Code The data in the Area Name and State Code columns are text. The data in all of the other columns are decimal numbers. Your function will need to use the accumulator pattern to return a dictionary. The keys of that dictionary will be the state codes read in from the file (state codes are at index 6). For each key in the dictionary, it's value should be the smallest median rent for an efficiency in that state (median rents for an efficiency are at index 1). Important Hints: * You will really, really want to use the built-in csv…
Task 01 Write a function that takes a dictionary as a parameter. The dictionary holds student names as keys and their mid-term marks in the python course as values. Your function should get the student name corresponding to the minimum and maximum mark achieved by the student and return it to the function call. Then, finally prints the returned statement after the function call. Sample Input: {'Samin': 25, 'Lily': 28,'Akib': 17,'Salma': 22, 'Imon': 20 } Function Call: function_name({'Samin': 25, 'Lily': 28,'Akib': 17,'Salma': 22, 'Imon': 20 }) Sample Output: Highest scorer: Lily Lowest scorer: Akib Sample Input: {"A":60,"B":30,"P":2, "R":8, "S":33, "T":88} Function Call: function_name({"A":60,"B":30,"P":2, "R":8, "S":33, "T":88}) Sample Output: Highest scorer: T Lowest scorer: P
▾ Part 2: Course Registration The time has come to register for courses at Stony Brook University. Complete the function register, which takes three arguments: a dictionary that maps a course's name to its number of credits (course_credits); a list of courses a student wants to take (courses); and a maximum number of credits the student is willing to take (max_credits). The function iterates over the courses list and attempts to register the student for each course, in sequence (use a for-loop, not a while-loop). "Registering" for a course means to add the number of credits of a course to a running total. If registering for a course would bring the total number of credits over max_credits, skip that course and continue on to the next one in the courses list. The function returns the total number of credits the students successfully registered for. Example #1: register ({'MAT 131': 4, 'PHY 131': 3, 'AST 200': 1, 'WRT 102': 3, 'PHY 133': 1}, ['MAT 131', 'WRT 102'], 12)) Return value: 7…
IN C PROGRAMMING LANGUAGE PLEASE DO THE FOLLOWING USING STRUCTURES IN C , 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.

Language: C Write the function convolve that will calculate the confolution of two functions f, g on [0, t] interval. The convolution is defined as (f ∗ g)(t) = Z t 0 f(τ )g(t − τ ) dτ for f, g : [0, ∞) → R. The argument function f and g should be passed by pointers. The integral should be approximated by the Riemman sum, i.e., Z b a f(x) dx = Xn i=1 f(xi) ∆x, where ∆x = b−a n and xi = a + i ∆x. Define the functions func1, func2 and func3, that return sin(x), cos(x) and x 3 respectively. Use these functions to calculate the convolution of f = sin(x), g = sin(x) f = sin(x), g = cos(x) f = sin(x), g = x 3 for t = 2π and n = 1000.

Write a function that determines the number of missing entries for a specified column in the dataset. The function should return a string detailing the number of missing values.Function Specifications: Should take a pandas DataFrame and a column_name as input and return a string as output. The string should detial the number of missing entries in the column. Should be generalised to be able to work on ANY dataframe. ### START FUNCTION def total_missing(df,column_name): #code total_missing(df,'Age') Expected Outputs: total_missing(df,'Age') == "Age has 177 missing values" total_missing" (df,'Survived') == "Survived has 0 missing values"
Part C - advanced file reading You will need a Python repl to solve part C. Define a Python function named expensive_counties that has two parameters. The first parameter is a string representing the name of a text file. Each line of this text file will be a state code. The second parameter is a string representing the name of a CSV file. The CSV file will be portion of the US government's dataset documenting median rents in each US county. Each row in the CSV file has the format: Area Name, Efficiency, 1-Bedroom, 2-Bedroom, 3-Bedroom, 4-Bedroom, State Code Your function will need to use the accumulator pattern to return a new list. You will need to add to this list the Area Name from every row that meets 2 criteria: (1) The state code (the column at index 6) was a line in the text file named in the first parameter; AND (2) The median rent on a 1-bedroom apartment (the column at index 2) is over 1000.

Jupyter Notebook Fixed Income - Certicificate of Deposit (CD) - Compound Interest Schedule An interest-at-maturity CD earns interest at a compounding frequency, and pays principal plus all earned interest at maturity. Write a function, called CompoundInterestSchedule, that creates and returns a pandas DataFrame, where each row has: time (in years, an integer starting at 1), starting balance, interest earned, and ending balance, for an investment earning compoundedinterest. Use a for(or while) loop to create this table. The equation for theith year's ending balance is given by: Ei =Bi (1+r/f)f where: Ei is year i's ending balance Bi is year i's beginning balance (note: B1 is the amount of the initial investment (principal) r is the annual rate of interest (in decimal, e.g., 5% is .05) f is the number of times the interest rate compounds (times per year) The interest earned for a given year is Ei - Bi Note the term of the investment (in years) is not in the above equation; it is used…
