Hey:
My teacher is being such a hardass about this assignment, and he wants us to use arrays. I have NO idea what an array is or how it works other than it uses [] operators and it can handle alot of data. I have included a cpp that I wrote last week in about 40 min for a program scheme called "BASIC". Its a stupid program, but I have to replace the reference parameters "aka cp0,cp1" and "b_part, a_part" with arrays by tommorow at this time. I really really really could use some help with this, any help at all would be appreciated greatly. I apoligize for my lack of programming skill, and since im new to this language, please dont make fun of me 🙂
Sorry for the length...
