Your program has basic mistakes. How to call a function, for example. Please pick a book from [The Definitive C++ Books List](http://stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list) and start reading. — Mahesh, Jul 24 '13 at 17:59

Your code does not make any sense. There are many problems with what you have written

I'm not going to go through them all, but the most glaring is

if (option == 1) {
    void addcontact(info contactlist[]);
}

This is not how a function is called. Instead, it should look like

if (option == 1) 
{
    addcontact(x);
}

where X is an "info" type of object, which you don't have defined.

I'd strongly suggest finding some basic programming tutorials to get a better familiarity with what you are doing.

`X` needs to be an `info[20]` type of object – Mooing Duck Jul 24 '13 at 18:17 — Mooing Duck, Jul 24 '13 at 18:17
