Help a noob in C++

[Frenchb0ygenius]

After many delays...i'm finally learning C++...the book i'm reading is great, and it's been a smooth ride so far, but there is one thing I haven't been able to understand: How to call a function!

I just don't understand it the way the show it in the book. Like in one example they write a program that finds triangle numbers, and a certain function does this...here is how they call it:

cout << "Function returned" << triangle(4);

(here 4 is the integer used)

In another example they write a program that determines if a number is prime or not...here is how they call the function used:

if (prime(i))

I understand how to declare a function, and how to define one, but not how to call it.

btw im using Visuall C++ 2005 if that is needed.

FunctionName( any variables you're sending to the function );

I'm trying to figure out what you don't understand. You know how to declare a function, and you've seen their examples of calling functions... what is left?

Well, i guess since when they showed how to name a function they gave a certain format: type name_of_function(argument s), and they did for a lot of stuff like casting, loops, etc...i was just a little lost. Thanks Mister.
