Step $5$: Define a struct called Medicine with components name$($of type string$),$ quantity$($of type int$),$ and price $($of type double$).$

Step $6$: Define a class Pharmacy with private members numberOMediciens, $*p$ a pointer $($of type Medicine$),$ cost $($of type double$),$ and the void function findCost$().$ The class has the public void member functions set$(),$ void print$(),$ a default parametrized constructor, and a copy constructor. The function set$()$ reads unknown medicine names, quantities, and prices from the text file "Pharmacy.txt$"$ using the while statement while$($inFile $dots).$

Use the following driver and "Pharmacytu"

Implement all member functions

Enforce the principle of least privileged.
