Functions

A function has three things:

1. A body of code to execute
2. Optional input parameters
3. An optional return type and respective return value

Void functions

A function of type void does not return anything. An example would be:

void sayHello()
{
    print("Hello there\n");
}

Trying to use a return in a void function such as the following would result in an error:

void sayHello()
{
    return 1;
}

Typed functions

A typed function has a return type and can return a value of said type, here we have such an example of a function defined to return a value of type int:

int myFunction()
{
    return 2;
}

Parameters

Functions can take in parameters of the form <type> arg1, <type> arg2, ..., below is an example of such a function which takes to integral parameters and returns the sum:

int sum(int a, int b)
{
    return a+b;
}

Calling such a function is accomplished as such:

sum(2,1)

!!! warning Calling a function like this is not yet supported. It must be in an expression, hence one can do discard sum(2,1) for now till we have direct function calls implemented. See issue #71.
