Assume the following C code is stored in a file named main.c. Please split it into two files where each file contains one function. Specify the content of each file and extra files (and contents) that might be needed. void swap(int *a, int *b){ int temp = *a; *a = *b; *b = temp; } void main(){ int a = 5; int b = 6; swap(&a, &b); }

(Data processing) Write a C++ program that reads the file created in Exercise 4, permits the user to change the hourly wage or years for any employee, and creates a new updated file.

Program language: C++ A publishing company markets both hardcopy and eBook versions of its work. Create a class publication that stores the title and price of a publication. From this class derive two classes: book, which adds a page count, and digital, which adds a storage capacity in MG bytes. Each of these classes should have a getdata() function to get its data from the user at the keyboard and put a putdata() function to display its data. Add a base class sales that hold an array of three floats so that it can record the dollar sales of a particular publication for the last three months. Include a getData() function to get three sales amounts from the user and a putdata() function to display the sales figures. Modify the book and digital classes so they are derived from both publication and sales. An object of the class book or digital should input and output sales data along with its other data. Write the main function to create a book object and a digital object and test their…
