declaring functions

[Coxxej]

Im really confused with these....

whats does i mean and what does ! mean in c++

[geniusberry]

If you need help with functions, this website has a good tutorial that explains everything at http://www.cplusplus.com/doc/tutorial/functions/.

and ! means not in c++ like

if (n != 5) {
cout << "N is not 5;";
}

could you also elaborate on what i you are talking about?
