Q.2)Create
a class for inventory of Mobile containing Model_Number, Company_Name, Price, Stock as data members. Mobile can be
sold, if stock is available, otherwise purchase will be made. Write a C++
program to perform following functions :
i.To accept and display mobile details
ii.To sale a Mobile (Sale contains
Model_Number & Quantity of mobile)
iii.To Purchase a Mobile (Purchase contains
Model_Numbet & Quantity of mobile)
