Use C++:

Download Lab09.cpp (the given code) and the two input files music.txt and writer.txt. Read the given code. There is a base class called Person which stores a person's firstName and lastName. There is a Musician derived class and a Writer derived class (both derived from Person). A musician "is a" person. A writer "is a" person. The Musician derived class holds an additional member variable for the musician's instrument. The writer derived class holds an additional member variable for the writer's genre. These classes are implemented for you.

1) Please implement the Musician derived class and a Writer derived class.

2) Please implement the main() function to accomplish the following tasks:

- Scan the data from the input file and load that data in an array of Musician objects and an array of Writer objects.

- The two arrays should be allocated dynamically, so they are the exact length that is required according to their respective input file.

- Point the content of each array before releasing the memory and exiting the program.

- The variables numerOfMusicians and numberOfWriters (shown below) are intended to store the length of corresponding arrays. The string variables str1, str2, and str3 are intended to temporarily hold firstName, lastName, and third variable (instrument or genre) as each line is read from its input file and then set into its object.

int main() {

int numberOfMusicians = 0; int numberOfWriters = 0; string str1, str2, str3; ifstream fin;

// TODO: Open the file music.txt. Print an error message and exit // the program if the file cannot be opened. 5 pts.

// TODO: Read the number at the beginning of the text file. That number // indicates the number of musicians in the list (which is also the length // of the musicians' array). 5 pts. // // Dynamically allocate an array of musician objects. The array should be // the exact length needed to read the file. 10 pts. // // Use a for-loop to load the array with the content from the text file. 15 pts. // // Close the text file when you are done with it. 5 pts.

// TODO: Open the file writer.txt. Print an error message and exit // the program if the file cannot be opened. 5 pts.

// TODO: Read the number at the beginning of the text file. That number // indicates the number of writers in the list (which is also the length // of the writers' array). 5 pts. // // Dynamically allocate an array of writer objects. The array should be // the exact length needed to read the file. 10 pts. // // Use a for-loop to load the array with the content from the text file. 15 pts. // // Close the text file when you are done with it. 5 pts.

// TODO: Loop through the musicians' array and print all of its data. // Then loop through the writers' array and print all of its data. 15 pts. // Remember to release all dynamically allocated memory before exiting. 5 pts.

return 0; }
