You are required to propose FOUR functions to develop a complete student record management system. The function are insert, delete, search, update. In addition, you need to use sorted array to complete the system development. Write a program by extending the code from the lab. Think and implement 4 more functions in the program (compulsory function is sorting and searching) Your must build on top of the following code. //FileName: Student.cpp //This program illustrates attributes of class Student using simple data structure #include <iostream.h> class Student { private: struct Data { char Name[25]; char Course[30]; int Result; } stdata; public: void SetData(); void GetData(); };//class Student void Student::SetData() { cout <<”Enter student name:”; cin>> stdata.Name; cout<< “Enter student course: “; cin>> stdata.Course; cout<< “Enter student result:”; cin>> stdata.Result; };//method SetData void Student::GetData() { cout<< “\n…

Question 4: Complete the below function that takes a file name and a list as arguments and reads the text within the corresponding file, then creates a dictionary whose keys are the characters of the provided list, and the values are the counts of these characters within the text. If a character in the list is not included in the text, "0" should be written in the dictionary as the value of this character. The function returns the created dictionary as a result. If the file does not exist, then the function returns an empty dictionary. Here is an example case, assuming a file named "sample.txt" exists with the following content: sample.txt This is an example sentence. This is yet another sentence. ----. >> text2dict("sample.txt", ['a', 'b', 'c', 't']) {'a':3, 'b':0, 'c':2, 't':4} def text2dict(filename, characters):

Question 3. We want to implement a flex like system to carry information about students and the courses they are currently enrolled in. The input data will be present in two text files called student.txt and courses.txt. The structure of the student.txt file will be (rollnumber, name, date of birth , batch, major) as shown below: 18L-1112, Ali Maqsood, 02-feb-2000, 20, CV 19L-2113, Haider Saqib, 31-Mar-1999, 19, CS 20L-1111, Fatima Ahmed, 01-Jan-2000, 20, EE The structure of the courses.txt file will be (rollnumber, course code, coursename, credit hours) 18L-1112, CV314, Soil Mechanics, 3 19L-2113, CS210, Data Structures, 3 19L-2113, CS213, Databases, 3 19L-2113, CS217, Analysis of Algorithms, 3 20L-1111, EE111, Circuit Analysis, 3 201-1111.

Assignment 2 will require Array of records (structs) with file I/O is needed. the program will read its data from a text file named coins.txt. There can be 0 and up to 10 input lines, each line is formatted like the example below; Jane 30 cents in AU$ Joe 85 cents in EUR Jane 15 cents in US$ Names are one-word strings. The same name can be repeated in the data file but the coin values/currencies can be different. If the name is the same, your program must assume it relates to the same individual. You are asked to write a program that reads the data from this file. For each individual, the program must add up the coin amounts that belong to the same currency to obtain a total amount for that individual in that currency. It needs to compute the change to be given for that individual for each currency that individual owns. e.g, the example above shows Jane has 30 + 25 = 55 cents in AU$ and 15 cents in US$. The program needs to calculate how many coins (hereinafter referred to as change)…
