using namespace std;
// 1). Medicine ID
// 2). Medicine Name
// 3). Price
// 4). Manufacture company
// 5). Manufacture date
// 6). Expiry date
// 7). Quantity



// 1. Header file mein jo <sstream> use kiya hai for string tokenizing. Wo kahan pe use ho rahi hai
// 2. System("CLS") kis liye use kiya haii?
// 3.  using namespace std  ko Agar header mein hi globally declare kar den, to baar baar std::cout nahi likhna parta? Just cout likhen gy? Same for the (std:: string details) ko sirf (string details) likhen ge?
// 4. Medicine list ko file handling k through hi change krenge ? Apne according.
// 5. Username or password mein apne names likhny hain. 
// 6. Ab hum ne customer ka banana hai khud. Tw usy merge kesy kren ge like abhi to press 1 for administrator tha na. Press 2 for customer. Administrator k baad kya code likhen ge. Bas guide kar den


// 1). sstream is used for tokenizing the string for example you have one string (hello,world) and you want to put hello in one string and world in another string then for this purpose sstream is used;

//2).System("CLS") is used for clearing the console screen .If something is written on the screen and you want to empty it then it is used.

//3).I have removed the std and wrote usingnamespace std at the top instead of it and same goes for std::string

//4.There are two methods for changing the medicine list 

// a)Through code .Go in the menu  and select the update or insert new medicine and the list is changed.

// b).Explicitly go in the file and add a new row for the medicine but keep in mind the format , first write new medicine id then name write comma after each property name  the format is medicineID,name,price,manufacturingcompany,date,expirydate,quantity and write comma after every property;

//5.Just go in admin file and i have commented where you should write your name and password so write there.
