- Print Person Information from file In this lab you are asked to complete the function : print_person_from_file(person_name, filename). This function should read in data from the file filename and print the information for person_name if it is found in the file. The file filename contains lines, in comma separated format (with a 'csv' extension) For each line, the items in each field are as follows: Field 1 3 4 Name Place of Birth Date of Birth Children For Children: • a person can have 0, 1 or multiple Children Multiple children are semi-colon separated If a person has no children the field contains 'NA' For example, consider the following lines froma .csv file, where Fletcher_Margaret has 3 children, and Baker_Jill has 0 children (field 4 contains the string 'NA') Fletcher Margaret,Sydney,30-09-1921,Green Bob;Green Nancy;William Tom Baker_Jill, Melbourne,08-09-1973, NA Format for Printing If the person_name is found in the file, the format for printing the person information is as…1 2 var a = 6; 3 var b = 5; 4 var c = 0; 6 function mystery (numl, num2) { 7 var a; 8. c = numl + num2; 6. a = numl + num2 + C; 10 num2 - numl; document.write(c + "" ); document.write(a + "" ); 11 12 13 } 14 15 mystery ( 4, 3); 16 document.write(a + + b + ""); 17 document.write(c + "" ); 18 19 What value for 'c' does line 11 display? What value for 'a' does line 12 display: What value for 'a' does line 16 display: What value for 'b' does line 16 display: What value for 'c' does line 17 display:String data type is not allowed you can make use of CString instead (char arrays with null termination). Q1. Create an Input File with the following information regarding to inventory: Item_Id Price Quantity Availability Add atleast 10 records in input file. Where item_id will be of type int , price will be of type double , quantity will be of type int and Availability will be of type char representing the status y for yes the product is available and n for not available. Write a menu driven C++ program to perform the following four tasks in a single file, if user press option 1 the task 1 get solved and so on: 1. Display the Item_Id of the products which are not available in stock on screen. 2. Copy all the available products data in a separate file. 3. Read the original input file and update the price of each item by 10 percent increase in the original price and save the complete information in separate file. 4. Try to save the information processed in part 3 in the original…
- PHONE DIRECTORYDescription: Create a phonebook directory that will store the contact numbers of N persons. Your program should allow the user to add, view, delete, and update the contacts in the phonebook. Note that one person can have multiple contact numbers. The program will stop when the user command is ‘X’. Program command and entry should not be case-sensitive. That means commands ‘I’ or ‘i’ and the name “Jacky” or “JACKY” are the same. Each contact number can be 7 digits or 11 digits only. The user should input a string containing the command, name, and contact number(s) (Limit the contact number of each person to three). This string should be broken down into fields in order to separate the different values and store them in their appropriate variables. Use linked list in the implementation. Your node must declare at least four instance variables. Program flow: Command> I Jacky 09211234567 Remarks: New contact has been added. Command> V Jacky Contact…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. Code:from Contact import Contactimport pickledef load_contacts():""" Unpickle the data on mydata.dat and save it to a dictionaryReturn an empty dictionary if the file doesn't exist """try:with open("mydata.dat", 'rb') as file:return…Data File: Example #1AAAAABBBBBCCCCCDDDDDAAEBCBAFBBCDCECDADDEFEEFFFExample #2AAATAABTBBBBCCCCTCDDTDDDAASAABBSBBCCSCCDSDDDEEEAEEFBFFFDDF Write a program that will give the user a brief introduction, then allow the user to type in the name of the file to be analyzed, the name of the data file to generate, and then process the data to match the output that is shown below. This DNA test measures the various parts of the sequence and assigns them a letter. While the letters could be anything from A to Z, the only letters that matter for this test are the letters {A,B,C,D} all other letters can be ignored completely. A sample will be tested, given a length of time and then tested again. Each time the scientist will generate a line of data. Here is one Example: Example #1 AAAAABBBBBCCCCCDDDDD AAEBCBAFBBCDCECDADDEFEEFFF At first glance the sample looks significantly different after the second test. But if you look at the data, you will note that since we only care about A,B,C,D’s that the…
