I am learning C for a class I am taking and a homework assignment asks us to makes a list of integers, divides the list into a number of segments, and displays each segment in reverse order. We need to use the function malloc to dynamically allocate locations for variables a and b. The full assignment is below. I am not too familiar with C and I don't know how to split the list into two arrays.
Add a function to get the CPI values from the user and validate that they are greater than 0. 1. Declare and implement a void function called getCPIValues that takes two float reference parameters for the old_cpi and new_cpi. 2. Move the code that reads in the old_cpi and new_cpi into this function. 3. Add a do-while loop that validates the input, making sure that the old_cpi and new_cpi are valid values. + if there is an input error, print "Error: CPI values must be greater than 0." and try to get data again. 4. Replace the code that was moved with a call to this new function. - Add an array to accumulate the computed inflation rates 1. Declare a constant called MAX_RATES and set it to 20. 2. Declare an array of double values having size MAX_RATES that will be used to accumulate the computed inflation rates. 3. Add code to main that inserts the computed inflation rate into the next position in the array. 4. Be careful to make sure the program does not overflow the array. - Add a…

Zybooks C++ 1.7 LAB: Introduction to data structures labs Step 1: Producing correct output Three commented-out lines of code exist in main(). Uncomment the lines and click the "Run program" button. Verify that the program's output is: 2 + 2 = 4 Unknown function: PrintPlus2 Secret string: "abc" Submit your code for grading. Your submission will pass the "Compare output" test only, achieving 1 of the possible 10 points. Step 2: Inspecting the LabPrinter class Inspect the LabPrinter class implemented in the LabPrinter.h file. Access LabPrinter.h by clicking on the orange arrow next to main.cpp at the top of the coding window. Member functions Print2Plus2() and PrintSecret() print strings using std::cout. Step 3: Implementing CallFunctionNamed() Remove the three uncommented lines from main(). Then implement the CallFunctionNamed() function in main.cpp to handle three cases: If functionName is "Print2Plus2", call printer's Print2Plus2() member function. If functionName is "PrintSecret",…

Hello, I have an assignment in the python program. Professor gives me a text like this: January.txt 217283921200.5619.18,29.15,78.75,212.10100,20,410.29 The first line is an account number, the second line is the beginning balance, the third line is withdrawn and the last line is deposits. How can I separate every single line to read them. Can I use the loop function? Below is the assignment direction. Thank you very much ___________________________________________________________ Complete the following program: a) Read in and store the data from the file called “January.txt”. This file includes the customer’s account number, beginning balance, withdrawals, and deposits. (In that order) Note: Make sure you look at the file before you begin the project! b) Prompt the user for his/her name and age. c) Convert the customer’s name to a username that consists of the first letter of the first name, the first 5 digits of last name, and the customer’s age.(All letters should be lowercase)…
