Change main() to int main()

[Duthomhas]

Better than that, why don't you just do your own homework and get yourself an 'A'?

[kbw]

It's already a C++ program. Why do you think you need to change anything?

[ralgrado]

this is not my homework...... this is my miniproject in c ...so i want to convert it to c++.....im beginner,i want someone to teach me hot to convert it to c++..that why i post this

[Moschops]

C is (very nearly) a strict subset of C++. Fix your main() and it becomes C++

[AbstractionAnon]

Here a few links to get you started:
http://www.cplusplus.com/articles/1ywTURfi/
http://www.cplusplus.com/articles/S3wTURfi/
C++ is an object oriented language. Decide what the objects are in your program and make classes to deal with them.

p.s. Learn to use code tags

Do you want to convert it into seperete class and then implement it in the main() function .

[Aramil of Elixia]

You also need iosteam instead of stdlib dont you

[Moschops]

You also need iosteam instead of stdlib dont you

That would be better C++ style, but stdlib is still C++ (as indeed is cstdlib).

[Aramil of Elixia]

Im sorry i meant to write stdio. I use stdlib.h for abort() but can i use cstdlib as the proper c++ substitute?

[Moschops]

Yes you can :)
