No buddy, ya don have to.
Lisn up, for extremely huge datas like the 200 variable array, u're talking 'bout, the latest industry standard is to use database management programs like oracle etc. Later on, you can integrate this data with your C++ program. Some programmers even use MS Access. Alternately the problem can be solved by Object Oriented Programming or OOP approach. But since you are new to C++, I'll leave it for your book to explain.
