Yeah, but at least I spotted why he couldn't access the function.... Seriously, you're right, of course. *blush* Christian The tragedy of cyberspace - that so much can travel so far, and yet mean so little. And you don't spend much time with the opposite sex working day and night, unless the pizza delivery person happens to be young, cute, single and female.

ok... a functoin is declaring somthng like voide SetName(char Name) { } correct? then if you want to use that in your program you could do somthing like int main() { SetName("Judy") return 0; } now... even though this wont do anything... "because there isnt anything int eh SetName function... this would work right? i declared my void SetName(char Name); in a header class named Student so: void Student::SetName(char Name); { } int main() { char SName[32]; cin >> SName; SetName(SName); return 0; } wouldnt this work... what am i forgetting... i keep getting a undeclared identities thing. Thanks all! ~SilverShalkin :rose:

If you made the function static, you could call it on Student itself, otherwise you need to create a student and call the method.

The funny thing is that it might have worked for the guy if he casted it and he'd have used it without realizing it was a typo error Nish

Blast. My bad!!! He'd have been casting the pointer address to char :( Nish

Student s i will always keep adding students.. could i make s an array? that always changes? like: Student s[nextname]; ? Thanks All ~SilverShalkin :rose:

No, you cannot do that - you can make an array of students ( or better yet, a std::vector ). That would be the point - each student knows what it's name is. To make s an array you would put Student [12] s; ( from memory ) Christian The tragedy of cyberspace - that so much can travel so far, and yet mean so little.

And so i wouldnt beable to make the [12] into somthing that increases everytime you call it? oh,... this project is a learning project... its not ment to go the easy path or anything, its ment for me to understand the class and using header. there is a couple other ways i probably could do this "me" you know, the guy that know the least on this forum... :) thanks again! c-ya ~SilverShalkin :rose:

That's what you need to have a dynamic array.

Use the correct decl. void Student::SetName(char* Name); { }
Rama Krishna wrote: void Student::SetName(char* Name); { } You would actually need to remove the semicolon: void Student::SetName(char* Name) { }
