# Mo_7.
![Description
# Write a class called Song in a file called Song.h with three fields:
Title (string)
Singer (string)
Chart Position (int)
# Place these method headers in the Song.h file
1. Getter and setter for each field
2. Other methods
1. Song();
// default constructor
2. Song(std::string title,std:: string singer, int chartPosition);
// custom constructor
3. std::string toString();
// returns object as a string
4. bool operator<(Song other)
// overloads the < operator -returns true if the chart position of this song is less
other's
5. friend std::ostream& operator<<(std::ostream&, Song* s);
// overloads the << operator
#Write the implementation of these methods in a file called Song.cpp
# Write a driver called SongMain.cpp that does the following
a. Creates a dynamic array that reads in data from SongData.txt and
b. Populates the array by constructing song objects from this data
c. Uses the non-recursive selection sort method to sort the array
according to chart position (uses the overloaded < operator on Song
objects)
d. Prints the top ten songs in the chart (uses the overloaded <<
operator)
e. Searches for any song by title and returns chart position
asks user for song title, does linear search returns position or -1
