Could you answer and explain the following question.

Given main() and the Instrument class, define a derived class, String Instrument, for string instruments. Ex. If the input is: Drums Zildjian 2015 2500 Guitar Gibson 2002 1200 6 19 the output is: Instrument Information: Name : Drums Manufacturer: Zildjian Year built: 2015 Cost : 2500 Instrument Information: Name: Guitar Manufacturer: Gibson Year built: 2002 Cost: 1200 Number of strings: 6 Number of frets: 19File is marked as read only Current file: main.cpp 1 #include "StringInstrument.h" int main( ) { Instrument my Instrument; StringInstrument myStringInstrument; string instrumentName, manufacturerName, stringInstrumentName, stringManufacturer, yearBuilt, 8 cost, stringYearBuilt, stringCost, numStrings, numFrets; 9 10 getline(cin, instrumentName); 11 getline (cin, manufacturerName) ; 12 getline(cin, yearBuilt); 13 getline(cin, cost); 14 15 getline(cin, stringInstrumentName) ; 16 getline(cin, stringManufacturer); 17 getline(cin, stringYearBuilt); 18 getline(cin, stringCost); 19 getline(cin, numStrings); 20 getline(cin, numFrets); 21 22 my Instrument .
