Dealing with strings

Ok I'm mainly from a Java background, so at the moment I converting some of my Java programs into C++. I was unaware that C++ dealt with Strings in a different way, i.e. using character arrays. I have the following header which converted directly from java. Due to my unfamiliarity in dealing with strings in c++ there appear to be quite a few errors(27) which I can't iron out. Also I think I should have some pointers in there somewhere, but since Java hides pointers I don't yet understand them and quite frankly they scare me. #include < iostream.h > #include < string.h > class Bank { public: Bank(); ~Bank() {} int addCred(int addCred) { currCred += addCred; totalCred += addCred; return currCred; } int giveChange(int deductCred){ currCred -= deductCred; totalCred -= deductCred; return currCred; } void updateCred(int cred) { currCred = cred; } int getCred() { return currCred; } private: int currCred; int totalCred; }; Bank::Bank() { currCred = 0; totalCred = 2000; } //Bank::~Bank() {} class Display { public: Display(); ~Display() {} void showDisplay(char displayText[50]) { text = displayText; cout << "DISPLAY:: " << text; } void clear() { text = "READY"; showDisplay(text); } private: char text[50]; }; Display::Display() {} ~Display::~Display() {} class Keypad { public: Keypad(); ~Keypad() {} char[] getCode() { cin.getline(code, 10, '\n'); strupr(code); return code; } private: char code[10]; }; Keypad::Keypad() {} Keypad::~Keypad() {} class Product { public: Product(char itsName[50], int itsPrice); ~Product() {} char[] getName() { return name; } int getPrice() { return price; } private: char name[50]; int price; }; Product :: Product(char itsName[50], int itsPrice) { name = itsName; price = itsPrice; } Product::~Product() {} class Tray { public: Tray(char itsCode[10],Product trayItem); ~Tray(); char[] getCode() { return code; } Product getProduct(){ return prod; } void dispense() { quantity--; } int getQuant() { return quantity; } private: int const limit = 20; int quantity; char code[10]; Product prod; }; Tray::Tray(char itsCode[10],Product trayItem) { code = itsCode; prod = trayItem; quantity = 20; } Tray::~Tray() {} Edited by - pdstatha on January 1, 2002 8:48:09 AM BTW the classes are for a vending machine Edited by - pdstatha on January 1, 2002 8:51:55 AM

just always use namespace std and it will work. When using string don''t use any of those C functions like strcpy, strlen, etc... use the methods of the class. Anything that you don''t find as part of the class will be in algorithm. Oh and due to a mistake fstreams do take char* instead of strings in their constructors. Fortunately the string class has a method c_str() which will return one.
