- make a program in c++ which has a class named Student. The class should have appropriate data members to store the enrollment number, name and email of a student. make an appropriate function for taking the basic information like enrollment number, name and email from user. In addition, make another function to append the data to a text file on hard disk. Furthermore, there should be a function which displays the content of the file on console. In the main function create objects of the above class and call the appropriate functions to add information of a student, store it in a file and display on the consoleDiscussion: Files with .h extension are called header files in C. These header files generally contain function declarations which we can be used in main C program, like for e.g. to include stdio.h in C program to use function printf() Exercise 2. Creating myhead.h : Write the below code and then save the file as myhead.h or you can give any name but the extension should be .h indicating it’s a header file. // It is not recommended to put function definitions // in a header file. Ideally there should be only // function declarations. Purpose of this code is // to only demonstrate working of header files. void add(int a, int b) { printf("Added value=%d\n", a + b); } void multiply(int a, int b) { printf("Multiplied value=%d\n", a * b); } Including the .h file in other program : Now as we need to include stdio.h as #include in order to use printf() function. We will also need to include the above header file myhead.h as #include”myhead.h”. The ” ” here are used to instruct…In C++. The New York Times newspaper has published “best seller” lists since 1942. Book sales are tracked nationwide, leading to a list of those books which have recently sold the most copies. You will design, implement and test a C++ program which allows the user to search a subset of the books which have appeared in the New York Times best seller lists. For simplicity, the data set will only contain those books which have reached #1 on either of two lists (fiction and nonfiction) since 1942. The file included named bestsellers.txt contains the complete data set. Each line of the file contains the information for a separate book, which includes: title, author, publisher, date it first reached #1 on one of the best seller lists, and category (fiction or nonfiction). There is a tab character ('\t') between fields.Add a BestSellers class that contains a single attribute of a vector of Book objects, an addBook method that receives a Book object and adds it to the vector, and a display…
- C++ Programming I: Free Fall Calc In C++ use Functions with Pointers and References Your free fall calculator program will calculate the time it takes an object to fall until it hits the ground. This program requires functions. Place the function prototypes in a file named FallFunctions.h. Create a global constant for ACCELERATION in the .h file, too. Use a comment to define the units for acceleration. Place the associated function implementations in FallFunctions.cpp. Call all functions from main, which is located in your Driver.cpp. In main, you will call the Header function first. Then, start a do another loop. Inside the loop, call the AskHeight function using a reference to height to ask the user for the height of the fall in feet. Next, call the TimeToFall function using a pointer to time to calculate the time it takes the object to fall. Pass time and height to the WriteResults function to write the information in a neatly formatted string. The string is then returned to…Use the prototype function shown in question, Write comments and attach screenshots. Try to do asap The language used here is C++ Develop a C program that processes a file called “grades.txt” containing a list of student grades and outputs the minimum, maximum, and average grade contained within that file. Your program should make use of the following function prototype: void grades(FILE *inp, int *p_min, int *p_max, float *p_ave); Sample Output: Input File: 2 3 9 10 15 17 25 30 40 45 78 81 90 Output: Min: 2, Max: 90, Ave: 34.23Please send me answer within 10 min!! I will rate you good for sure!! Please provide screenshot of code and output with explaination!! Write a C program that implements and tests a function that simulates strcmp function. You should not use functions from <string.h> library. You may use array and/or pointer notation to define the functions. More precisely, you should implement this function: Hint: int myStrcmp (const char *s1, const char *s2) This function compares the string pointed to by s1 to the string pointed to by s2. If the string pointed to by s1 comes before the string pointed to by s2 in dictionary ordering, then -1 is returned. If the string pointed to by s1 is the same as the string pointed to by s2, then 0 is returned (the compare function is case sensitive). Otherwise, 1 is returned. C program
- Programming Assignment - Employee Data Processing Submission: 1. Submit as one file of type *.cpp 2. Submit it on the Blackboard within the due date and time (Submission via email will NOT be considered!) 3. Assignment ID: PA Employee Data Processing The Program Details: Implement a program in C++ that does the following: 1. Requests the user and Reads the input of at least 10 Employee full names (first names, middle initial, and last names), pay rate per hour, and the number of hours worked per week (for at least SIX weeks) for each of the employees. 2. Saves those inputs (use arrays to store them). 3. Calculates the amount of salary earned per week, average salary o6 weeks. 4. Displays the output, i.e., employee name (with first name, middle initial, last name in separate columns), each Week salary, average of 6 weeks salary. Make sure the output format is neat and follows a column format with proper column headings. (Your program must work for any similar input data entered as…Use C++ Modify the code to have operator overloading functions with the following operators.==, <, <=, >, >=, +, -, *, /Use the Rational interface and main code in the next page.

In this lab, you will replace the existing functions with more flexible ones, and you will add additional functions to perform modular tasks. The "old" functions for displaying "hello", "goodbye", "invalid selection" and "invalid input" all do basically the same thing. They simply display a message to the user. Replace the old functions with a new function called displayMessage. The function should take a string argument, and display it. void displayMessage(string); //prototype The old function for displaying the menu would be more useful if it also returned the menu selection. Replace the old function with a new one called getMenuSelection that will return the menu selection as a char variable. Make sure to use the function result when you call it (assignment, display, use in expression, another function call, etc.). char getMenuSelection(); //prototype Wouldn't it be nice to check the menu selection for an invalid input? How about checking to see if the exit…
- For C++, How would I call or use a function that is passed by pointer or a reference? How would I use these in this example below? I understand how passing by value works, but when it comes to passing by references and pointers, that is when I get confused. #include <iostream> using namespace std; // passing by reference in this function void pass_ref(int &ref); // passing by pointer in this function void pass_ptr(int* ptr);Write the following program: Write a C++ program to print unique words in a file. Write a C++ program to print how many words in a sentence from a file. By using student class with member’s variables and member functions, write a C++ program that read student information from text file. The following program shows the Operators Overloading for addition(+) operator function, now for the same operators overloading program do the operation for subtraction(-), multiplication(*) and division(/) functions.This exercise assesses the skills required to develop user defined functions, and pointers.Exercise 1Write a C++ program with two user defined functions. The first function named “functionWithArray” takes two user input arguments of character types and return True if first argument is smaller than the second argument (alphabetically) and returns False otherwise. Write the second function named “functionWithPointers” which behaves like the first functions but uses pointers to receive the arguments.You may assume that both character arrays contain only lower-case letters, and no blanks or other nonalphabetic characters. Write a suitable Main function to test these two functions. Sample Output:Enter First String: C++ProgrammingEnter Second String: JavaProgrammingAccording to functionWithArrays: 'c++programming' is smaller than 'javaprogramming'.According to functionWithPointers: 'c++programming' is smaller than 'javaprogramming'.
